I've always ridden BMX or mountain bikes and currently have a hardtail that I use for my 'do it all'... i mainly ride trails, canal paths, woods and general bumbling about, but of late I find myself being drawn to and looking at gravel bikes. My questions are, am I going to use it, will I benefit from a 'gravel' bike? What can it do that my hardtail can't? I guess I'm trying to understand the real purpose of them. Please, no jumping down my throat, im not slandering them at all.

Well for me they're all about exploring tracks and bridleways - mainly from home - kinda exploring really - and being able to link bits together via road / lanes. I'm certainly back to where I started late 80's with mtb'ing - "wild but mild" in now my kinda thing - and I love it.

There's about three squillion threads on this, with all viewpoints represented. Scroll back a bit until you find a couple.

What can it do that my hardtail can’t?

Nothing, really. But it'll be much quicker on road/flat gravel, in a headwind and more comfortable for long days/lots of miles (multiple hand positions on the drop bars).

They're nearly as fast as a road bike on tarmac or towpath or any smooth gravel, and will make tame bridleways/forest tracks more 'interesting'.

I use my gravel / all road bike for all you suggest and as others mention it is great on road sections as well as off-road and the extra hand positions aid comfort.

That said, I do find that I spot things I’d like to come back to on a MTB. I didn’t have one till recently after mine was stolen. But I recently went for a LLS HT for a contrast and to get playful on the steep stuff but as it is a HT it is still fairly good (albeit slower) to get there.

What ta11pau1 said. Anything from “road rides using off-road to bypass the nasty bits” to “foraging for tucked-away singletrack linked by bits of road” to “out for a big, long day taking in whatever looks nice along the way”. See also tourers, audax bikes, anything that’s got curly bars and takes at least 37mm tyres. But it depends where you live: if all your off-road is babyheads and boulders then I’d stick with a hardtail.

OP, do you have any friends that would let you borrow one to try out?
Failing that, buy some skinny tyres for your hardtail, lock off the fork and rattle it round a few of your local places.

did 100k on the north downs recently and rode all the popular trails in the surrey hills this weekend on mine.
there is definitely a gravel bike scale from road to almost mtb so you have to pick carefully.

A gravel bike will get you to the bits where a gravel bike is shit much quicker.

my gravel bike is a mtb in disguise. Curly bars, but 2.2" tyres. So, not great at anything as its slow on the road, and slow off road, but it goes anywhere and everywhere.

Honestly for what you do a gravel bike will be perfect. im in zone 3 london very flat and a few small woods dotted around so its perfect to link them together using my gravel bike. if I want a longer day I can do like a 60+ mile loop to the edge of the m25 and back or even head out to surrey from my door. All these things would not be possible even on a HT, i mean it would but it would just be hard going.

People that moan about gravel bikes likely don't own one or realise there are other types of bike riding to do than their normal blue trail at a trail centre. Also the other joy if you commute the bigger tyres make them way more comfortable on our awful roads.

I like mine, but not as a replacement for an MTB (or a road bike, for that matter), not by a long stretch. But then again I live where:

all [my] off-road is babyheads and boulders

I use mine as a bike for everything. Family rides, pulling a trailer, commuting etc. But especially taking the longer route home from work taking in some singletrack, which was the main reason for buying.

If I could have only one bike, it'd probably be a gravel bike but fortunately I don't have that constraint.

They'll do that too 😀

Still need to take mine around bedgebury, they're really sanitising the place now, new section that has been redone just opened up and it's gone from a semi techy, rooty climb, to smooth as a snooker table gravel trail, with a strange set of 3 or 4 rollers, at the top of a climb...

Also the other joy if you commute the bigger tyres make them way more comfortable on our awful roads

This so much. 47mm WTB Byways roll quick as you like but with 30psi they're comfy too.

I originally bought my gravel bike for commuting and so I could take in some light trails/singletrack on the way home. I still prefer riding my MTB when I can but it's much easier to hop on the gravel bike and go for a ride places where a full suss is too much effort, which means I get out more. I think another plus is that it has made my MTB skills sharper and it keeps me fitter as I tend to do more miles on it. I did destroy the stock wheelset on the gravel bike though, so have to remember to reign it in a little on the rough stuff!

My questions are, am I going to use it, will I benefit from a ‘gravel’ bike? What can it do that my hardtail can’t?

It can go a bit faster on road and gravel with same effort
It can be more comfortable on long rides on road and gravel due to body position along with change of hand positions

If you don't do long rides or have a desire to go very slightly faster for same effort then can't see how you would benefit from one over a hardtail

It'll not just be quicker on road - a bike built will feel overall more positive and rewarding for your effort on road. But of course worse off it, so.you choose..it won't revolutionise anything but you might enjoy it.

Another weekend, another long shift on the gravel bike.

The last few big rides I've done have incorporated roughly 45% tarmac, 45% gravel track, 10% easy MTB.

The tarmac is relatively fast and easy, certainly not a chore, useful place to chill out, enjoy scenery, rest legs for gravel sections. I've also taken to exploring a lot of 'dead end' tarmac climbs to reservoirs etc. that I might not have bothered with on the road bike, especially if the tarmac ends and continues as landrover track.

The gravel tracks are awesome, the bike flies along so it needen't be 'easy pootling' it can be balls out puddle dodging, loose corner sliding, undulation pumping flat out fun. I guess if you don't enjoy pedalling as much then that mighten't appeal, think of it as a fun downhill section but you have to propel the bike, not gravity.

The MTB stuff we do is the old 'classic MTB' territory (a point I've been labouring in some write ups) so it can be muddy singletrack, old cart tracks, rocky quad tracks etc. None of it is truly 'gnar' so by the time the gravel bike gets out of its depth (on my rides this is typically the steeper looser climbs where 40mm slicks get overwhelmed) I'm not really losing out much to an MTB, an extra 5 minutes hike-a-bike perhaps. Descents are a bit more careful but as others point out, it just means that a descent that might be tame on a modern MTB becomes exciting again...

Overall, it's brilliant, a new way of exploring the highlands and those routes that would maybe just have been a chore on the MTB but impassable on the road bike.

My questions are, am I going to use it

Ask where would you use it? You may find that there is nowhere you wish to ride that would be improved by having a gravel bike. You may find that you love the speed and efficiency that a gravel bike gives you to get from your door to explore. You may instead find that your hardtail does everything that you want it to do.

will I benefit from a ‘gravel’ bike? What can it do that my hardtail can’t? I guess I’m trying to understand the real purpose of them

Gravel bikes (IMO) at their best are just versatile bikes. I can see how they would be confusing to younger generations especially from an BMX/MTB background. Actually I was confused when I first saw a Genesis Vagabond in my LBS. For about 10 minutes. 10 mins after that I had it in the back of the car on a long weekend demo up and down the Tarka Trail, local commutes on farm tracks and lanes, cheeky SWCP and 🤣. For me it felt so much better for all that than on my hardtail. I couldn’t give it back.

I sold the hardtail as it was now evident that it wasn’t being used properly since moving/needs changed. I just still had a hardtail because I’d had hardtails for decades and was a serial swapper/upgrader. Even though my current riding didn’t at the time really benefit from a hardtail as 90% of my riding was paved and tracks commuting, bimbling and exploring. Long hours in the saddle. Lots of little lanes, steep road climbs, etc.

To an old duffer like me who started his cycling life on road bikes/road bikes hacked into cross bikes (and then ‘ATB’ before MTB took off) then a gravel bike seems to sit between road and ATB/MTB. Hence ‘versatile’

I tended to call the Vagabond my ‘ATB’ (it wasn’t a ‘gravel bike’, it was a monstercross) but very much a 1990s feel of ‘ride most anywhere any distance from your front door on a rigid bike’.

IMO a gravel bike (ironically) makes sense in the way that everyday bikes used to make sense before everything became a niche within a niche. It’s just an allround bike without an emphasis on either roadie racing or mountain-biking/performance. The cynic in me would say it was a way to get dyed-in-the-wool mountain bikers to buy a second bike, or to confuse them into revisiting the 1980s and 1990s now with disc brakes. Or worse still - a gateway to roadie fundamentalism 🤨

The rationalist in me would say that either a dedicated road bike or mountain bike is not necessarily a ‘versatile bike’ so the ‘gravel’ gap in the market was there for people who want a bike for exploring, bimbling, commuting, light touring, keep fit on local multi-surface routes etc without paying too hard a penalty if caught on a long stretch of perfect tarmac or imperfect gnarmac.

You can do it all on a hardtail. Or a BMX. Whether you’d want to is a different matter! Same goes for a gravel bike. Depends what ‘all’ is to you, I suppose?

Also easier to hoick over gates/styles, that 3-4 kg makes a difference. It's a one handed shoulder press, unless I've got 2 full water bottles. Versus almost giving myself a hernia lifting the FS bike with fox 36's/coil etc...

I'm looking to replace an old Dawes touring bike with a more modern gravel equivalent. I think the trick for me is remembering no matter what the marketing says they are ROAD bikes. Capable, more interesting, different handling whatever but ultimately road bikes. So if your someone who doesn't like or get road bikes....
For me living near the south downs and with loads of bridleways and poorly surfaced country lanes with lots of places to stop and look at, they make sense.

Dunno if I quite agree with you. For starters "Gravel bikes" appears to cover a broad range of definitions from 2.3" tyre clearing, 'would be an MTB if not for the drop bars' to 'pretty much a road bike but it clears 32mm tyres'

I'm always a bit sad to see "altura-man" specials, where he's clearly gone to the Local Evans, C2W voucher in hand, been wowed by the disc brakes. Then had them fit every possible pannier available for pedaling to work with a months worth of food, clothing and a massive laptop. After a week having found it a bit much effort he's gone back and made them fit 28c road tyres, almost always marathons.

Those bikes are only ever going to do "work packing" on a 10 mile tarmac commute, 3 days a week, and never really get used for what they're capable of...

Surely if fitting 2.3 tyre is the appeal of a certain bike your very close to being in denial it's a mountain bike?

With the caveat iv not ridden Amy gravel bikes with that setup and j may be totally wrong.

Schwalbe marathons do have a place.... But dear god it's impressive how utterly joyless they can make any bike.

They are great for canal towpath and bridleway riding. Comfier and more robust than a road bike with a slightly less arse up riding position (depending on model) and less drag than a MTB. Plus they are fun. Fun is always good. I’m about to buy another one.

I use a Cannondale Topstone (G-One Allround Tyres) as a one bike solution for mostly road and light trails and gravel and it's great at both. It isn't slow, it is more than capable of keeping up with road bikes and should I turn off down a forest track or gravel path, I can. The folk that think they're a marketing gimmick, simply haven't ridden one.

I think the biggest drawback to my hardtail that is making me consider a gravel bike is that local to me is a lot of tarmac to link up the off road parts I enjoy tearing through, and on the 2.8 tyres I run it gets a bit of a chore after a while. I think I need to borrow or demo one rather soon. Thanks for all the views and opinions guys!

Mine flies on tarmac. There's a pleasure in hustling a gravel bike on 47mm 650b slicks along at 20+mph on a flat with a touch of tailwind/slight downhill.

Don't tell anyone, but I even go out for rides mostly on the road... SHHH!!
I avoid main roads though and end up exploring the single lane roads that criss cross the kent countryside.

It's all a spectrum. I don't have gravel bike but I have a rigid 29er with narrow (660mm) high sweep bars and 2.3" fast tyres; and it has old school angles which are a lot like gravel bike angles, meaning a 73 SA and 70.5 HA. The geometry makes a massive difference as it's really positive feeling when bashing along roads and winching up fire roads. And it's surprisingly capable on rough stuff too. It's a hybrid sitting squarely between gravel bikes and XC 🙂 The fat tyres are essential for me in South Wales, and the flat bars really add lots of control over drops. But on the other hand, it's still pretty good on road - much better than a trail bike, because of the geo really, and much better than my XC FS which has the same geo, because of the narrow bars and so on, and because the shocks are never really locked out on my FS.

Quite possibly, but then like I said "Gravel bike" is a pretty broad term.

But yeah the cynical part of me can't help thinking that the bike industry is now very keen to differentiate "Gravel" from road bikes (which now have discs and a bit of tyre clearance too) so they're pulling a mini swizz by stuffing 650b rims and 50mm(+) rims on gravel bikes where apparently rather than "bringing the trail alive" they kill the lumpy bits... Who knew eh?
See also gravel specific droppers, gravel specific suspension forks/stems/seatpost/frames...

To my mind a gravel bike is really just a simple ruffty-tuffty on/offroad drop-barred (if you like) hacking about/touring/exploring thing. The width of the tyres isn't really all that important...

Not many people saying that on this thread are there? The question was what can it do that an MTB cannot do. Bearing in mind there are even more variations of an MTB than variations of a gravel bike.
Take an XC MTB with fast XC tyres versus a gravel bike with very similar tyres and there isn't really much the gravel can do over the MTB.
Take a more road focused gravel bike versus a 160mm full sus MTB with knobbly tyres and there are loads of things each bike can do over the other.

+1

Some of the best rides I've done are when I head in a vague direction with the idea that I'll follow any bridleway signs I pass and see where they come out. Sometimes this involves 50 miles on tarmac in between the off road "sectors" & while an MTB would be over kill for my local bridleways it would also be a chore on the road bits. The gravel bike makes the road bits more interesting & the tame off road bits more of an adrenaline rush.

It really depends on where you live, I reckon. In N.Wales I have a CX/gravel bike for "old normal" commuting, but do little else with it. I'm in Yorkshire/Peaks for a few days though and it makes total sense here, being able to blat around lanes, old cart horse trails, sand/stone singletrack (compared to slate/rock) and some mild descending. Great fun.

Ssssh, don't tell people that. I have ridden the gravel roads in my area for 20 years on a range of bikes with tyres from 2.4 down to 25c. For the majority of the ride 25c are fine and it is what I have been using for the last year however they do become a bit sketchy when hitting sandy gravel or looser gravel with larger stones but they still get through it.
I am not bothered by comfort as I never ride more than 2 hours so my bike of choice for gravel roads is pretty much a road bike (just with much tougher tyres)

I have a gravel bike that I more or less use a road bike. I don’t know what the roads are like where you live but my old bike had 25c tyres and frankly it made riding horrible on the battered potholed roads where I live.

Gravel bike is fine on the road and I don’t notice much difference.

I dunno... I'm still trying to figure out what it is that, frankly, makes my gravel bike feel so fast in almost every scenario. I'm beginning to wonder if fast rolling 40mm semi-slicks are just the 'sweetspot' of all-rounder tyre design.

...or maybe I've just gotten very good at finding the sort of terrain that 40mm tyres excel at, I'm certainly not going out looking for steep muddy roots any more and not trying to climb steep grassy stuff (no Capital Trail for me!)

And another faux french biking tag, bravo lad!

How are they at pulling trialsy moves?

Not the best, but they're just slightly different shaped bikes, so if you can do trialsy moves on other bikes, you can use the same techniques. See Road Bike Party, RBP2, Chris Akrigg's back catalogur for more.

I think it is. Last night I did a couple of farm track descents where the surface was just loose stones. Because I'm on 2.3 tyres I could carve them up and have a blast - there's no way I'd have cornered that fast on 37c on that surface.

Also the bike is perfectly balanced, so when I slip I just drift. Now I've not had the chance to pin a gravel bike but whenever I've ridden drops having a low front and a high back which makes me fast on road also makes me front-heavy which suggests that in the event of slippage I'm going to lose the front first.

I'm surprised at how long it's taking for gravel bikes to have 29x ~2.35" tyre clearance to become mainstream, besides the odd brand such as the Salsa Cuttroat, anything above 700x45 still seems to be quite rare.

Wider tyres are obviously not going to fastest on easier terrain, but they will open up harder terrain.

The drop bars will normally make you more aero than a flat bar, so you will get more speed for your power and you will cover more ground over the same time period, often resulting in you feeling far less fatigued for your time on the bike... So instead of say doing a 4-5 hour road ride, you might do 2-3 hours on a flat bar bike.

The boundaries are getting quite blurred, if you have "gravel lanes" right on your doorstep then a flat bar machine might make more sense, but if you have to ride 5-10 miles on tarmac to reach your "gravel lanes" then perhaps a gravel/adventure bike makes more sense.

Hmm, I guess it's very frame and rider dependant, but I've had more fun slipping, sliding and drifting corners on my gravel bike than I ever had on my MTBs. Might just be because I'm getting more practice as the 40mm tyres break out easier! It's always the back that goes first.

I certainly love always trying to pin the inside line of loose gravelly corners, in the knowledge that at least I've got a track's width to 'drift' if I misjudge it...

This is quite bike dependent. The drop bar bikes I've ridden tend to be quite short which probably exacerbates it.

often resulting in you feeling far less fatigued for your time on the bike

I've found the opposite - to get aero I end up bent over more which is less comfortable. So I tend to spend less time on my road bike but of course I cover more ground.

I think this is because the market is still driven by or inspired by the US where graded dirt roads are commonplace. On the other hand, we in upland Britain have a surplus of rocky mountain tracks that make brilliant mixed riding, but they're rough enough to make small tyres a chore IMO; even when we have lots of fire-road they are in out-of-the-way places and they can still be pretty rough. My local fire-road in the woods for example starts off nice but the descent has loads of rain erosion, loads of loose stones, some bedrock, and a big concealed rock half way down one of the fast bits.

The other thing that differentiates MTB and gravel bikes is gearing. I couldn't use gravel gearing round here, it's just too tall and the trails are too steep. A more sprightly climber might get away with it.

Allow me to clarify my statement, when I said tyre width doesn't really matter I meant it from the perspective of what 'counts' as being a gravel bike, you can run a 28mm slick or a 56mm wide knobbly thing, and all points in between, it's more the application, if you're using the bike for mixed on/offroad riding, I reckon it's a "gravel bike"...
Obviously you can pick the tyres/wheels that best suit your preferred terrain(s).

If we're sharing tyre anecdotes, I'm on 38mm trail tech G+ currently which appear to be sufficiently armoured for use on an APC, roll nicely on smooth surfaces, behave on loose surfaces with a hint of drift and will probably kill me when proper winter starts and all the dust turns to slick mud, They're great!

I think that's changing, the "no rules" ethos of gravel bikes seems to be pushing people towards adopting big cassettes and sub 1:1 ratios, especially now 1x is an accepted concept for many both of the big S's are now playing the game with gravel specific drivetrain options. You don't have to use bodged Road bike parts any more...

I’m surprised at how long it’s taking for gravel bikes to have 29x ~2.35″ tyre clearance to become mainstream, besides the odd brand such as the Salsa Cuttroat, anything above 700×45 still seems to be quite rare.

I’d agree with this. One of the main attractions of my Kona Sutra LTD was the ability to run proper 29 x 2.2” MTB tyres in it should I need to. At the moment the 50c ones are ideal for the kind of riding I’m doing but I do like to have the choice as none of my other bikes provide sufficient overlap to fill that gap (i.e. I don’t have a 29er hardtail)

The cables on my Salsa El Mar are all externally routed. So I could in theory snip the cable ties (or use clips) and remove the bars with the brakes and mechs attached, and swap it over for a drop setup. Not cheap though because I'd need STI brake levers, but I could have more gravel/road wheels with say 45c and a road freehub and use road gears to go with it.

Too much work though 🙂

I don’t know what the roads are like where you live but my old bike had 25c tyres and frankly it made riding horrible on the battered potholed roads where I live.

The roads are crap where I live and I actually find riding on gravel more pleasant than the harder tarmac. Like I said, I am not bothered about comfort and prefer the feel of narrower tyres.
I had a bike a few years ago that would take 45c tyres so I put some on. Ruined the bike for me as it just felt more like an MTB which is not what I want to ride.

For me narrow tyres on rough roads the concern is more about knackering the rims.

I think it's all driven by volume rather than rollover (radius).

Some quick fag packet maths seems to indicate that a 700x40c is basically double the volume of a 700x28c tyre which is a noticeable benefit (IMO/IME) for that on/off-road mix of riding.
On top of that though a 650bx2.3" tyre comes out double the volume of the 700x40c tyre again,
however there's not much more volume to be gained by going to a 29x2.3" (less than 10% increase)...

So yeah despite my cynicism it seems if you're still not happy with the ride a ~700x40c tyre offers the next obvious step (in the same frame) is actually to go to 650bx2"(+)ish tyres as it substantially increases tyre volume, improving the cushioning/grip a tyre offers , but will more than likely fit in an existing gravel bike frame where a 29er (622x2.0"+) tyre just won't and you don't gain much more volume with it anyway...

Never a problem for me as the narrow tyres require high pressure so rims are safe. Narrow tyres and high pressures, I really don't care about comfort.
If I did rides over 2 hours I would very probably say different

OK... so I think the plan is im going to try and build one up from spares and more than likely fleabay bargains. Im aiming at as cheap as it can get, and ultimately its just going to be a hacking about and winter type bike. Where to start frame wise though is my question? I'm on the border of M/L on the majority of hardtails but appreciate the geo is totally different. Any tips and pointers appreciated.

PS... it doesn't need to look pretty or even be recognisable as a gravel bike. So long as I can wheel it out the shed and have some fun i'l be happy

If you're planning to build a drop-bar bike using an MTB frame, size-down as you'll want a top-tube about 50-70mm shorter due to the longer reach to the levers of the drop bars. Fitting a shorter, rigid fork can also lighten the front end / balance the handling due to the longer bars / stem.

It doesn't have to be a MTB frame, and still unsure on wether i'l use drop bars or flats. Basically what im saying is that I don't have a clue where a good starting point would be hehe

is it as easy as buying a cheap roadie and converting it?

Probably not (although saying that I bought a 531 tourer for notalot and use it on gravel on 28c. It has rim brakes, I don’t mind. Without mudguards it will go 32c maybe a bit more it’s a great bike)

Depends - where do want to ride it (whatever it is you build)? Fireroads, country lanes, towpaths ie 28c-40c clearance? Or somewhere more challenging ie >1.95”?

Look out for a Marin gravel/touring frame or bike. Got my mint Four Corners Elite complete with Rival groupset for less than £500 the other week and there’s been plenty of frames on ebay recently. Cheap way to see if you like it.

Guessing you are lighter than me 🙂 I run 95psi in 23c because I have no choice, and whilst it doesn't damage the rims if I hit a pothole, it doesn't do much for my teeth and bones.

Looking to ride it straight out of the shed, mainly country lanes, roads and singletrack

I'd get something like this (obv in your size)

https://www.ebay.co.uk/itm/Raleigh-Royal-touring-bike/193633790813?hash=item2d15792b5d:g:jtYAAOSwGfZfCiM4

Jazz it up with a clean, remove rack and guards, new 3mm bar tape, set the brakes nice maybe some Kool Stop Salmon blocks, make sure wheels tensioned well. Rag it around the lanes and light trails see how you like it on the 32c ‘rough road‘ side of things?

Try different hand-positions, riding on the hoods covering the brakes, cruising on bar-shoulders on long stretches, descending and braking deep in the drops. Shifting your balance between the contact-points, getting used to the different ‘flow’ of roads and tracks at such speeds

If after a few weeks you dislike it just sell the bike and think about what next. Nothing (or little) lost. If you love it then keep or sell and put towards a gravel bike or tourer with discs etc

‘Singletrack’ is the outlier. Which means you may be better on flat bars or even sticking with hardtail and putting suitable larger volume hybrid gravel tyres on better for road-sections. Maybe add some Ergon GP3s for those rides. Is what I did for my 29er MTB.

Depends on your type of ‘singletrack’ ie

My old British tourer on 32c will at a stretch go:

But never:

Yet all day/week on:

I am 72kg so probably on the heavy side in this forum full of cyclists. It probably doesn't do much for my teeth or bones either but again, I don't care about comfort. I am also riding fixed as well so not always as easy to unweight or hop over potholes at speed.
Realise I am in the minority here but just offering a different view to those that insist on 2" tyres on their bike.
I have tried them and for gravel and road I simply prefer the feel of the bike with lighter and narrower tyres. Comfort is not an issue for me and grip is not required on gravel (I just go a bit more careful on any sharp gravel turns - which are few and far between)

@molgrips

whenever I’ve ridden drops having a low front and a high back which makes me fast on road also makes me front-heavy which suggests that in the event of slippage I’m going to lose the front first.

That’s an interesting one. I was under the impression that cornering in the drops reduces the chance of front washout, and too little weight on the front increases that chance?

Bridleways, canals, Woods, roads...Everyone has one right near their doorstep. Exploring Google and plotting routes that stay off the main roads. It's great fun and an enjoyable alternative to riding trail bikes.

I love mine and usually the bike I grab to ride. Older age creepin and it fits into my relaxed cycling of ale cake and slow.

You kids can keep your enduro! 😁

This^

I did it with paper (OS Landranger) maps as a kid/teenager, used a red felt tip to mark out ever-increasing local loops, paying close attention to old farm tracks, towpaths, old railway lines. Would normally choose a landmark or place of interest as a destination, and hopefully a different loop back home.

Sometimes would come home hanging after being caught out on a farm track or forest road knee deep in mud and water, other times grinning like a dusty champ after racking up a surprise century (either by following nose or not having a map that day 😂).

Have always explored wherever I‘ve live by bicycle more than by any other form of transport as it’s efficient, intimate and fun in ways that neither walking or motor-vehicles can manage in a given time.

I remember first ever ride to explore Malvern Hills and back with a schoolmate (who borrowed my Dad’s 40lb Raleigh Wayfarer, two sizes too small, with a bent R/S pedal 🤣🤣🤣). It should have been just a 75 mile round trip from home. We arrived at British Camp (rained all the way, got soaked) and he made the mistake of putting a coin in the payphone and calling his dad Bob to boast about it. So Bob on phone says ‘tell you what, you lads carry on from there instead of turning back, you’ll knock ten miles off the journey.’

Thanks to Bob we somehow wound up in a Herefordshire town named Bromyard and put at least another 30 miles on our route, also getting lost a good few times trying to get home from this new lo(st)cation 😎. Knocking on doors to beg locals refill our water bottles. At least it stopped raining and the sun came out.

Trial by fire and water, fit as ****. Jumpers for goalposts. Happy daze. Don’t trust Bob (but in hindsight it made the day)

It's more about being low, because my MTB experience makes me feel a lot more vulnerable. If I'm on the drops and the front goes I'm hitting the deck hard and I have no chance to mitigate it. With a more centered position I feel I can rescue it or at least bail out nicely. Same reason I always go o to the hoods in traffic. It feels more defensive.

Can understand the fear-factor but it’s counterproductive in a couple of ways.

While tight-cornering is it preferable to slip sideways from on high CofG, or from low CofG? I ask my head this question and it says ‘low and slow‘. I ask the teenager in my legs and they say ‘high and fast‘.

It is more about control if the front does wash out. I would rather be riding with my 620 wide risers in a more upright position than my 40cm wide drops if ultimate control of the bike is the goal.

My questions are, am I going to use it, will I benefit from a ‘gravel’ bike? What can it do that my hardtail can’t?

IMHO.. Think of it as a road bike that handles crappy road surfaces, broken up lanes and byway links much better in a way that opens up new routes or from-your-door rides and you won't be disappointed. They're modern versions of a classic tourer with bigger tyres.
Think of it as any replacement for an MTB and you will be disappointed (assuming you have a jot of handling ability). Drop bars and tyres well under 2" are fun off-road but it's an underbiking kind of fun. TBH I tire of it after a number of hours, you get beat up.
The other disappointment is thinking that because it's fast on road unloaded it'll make a good/efficient bikepacking bike off-road. They don't, a rigid XC 29er will be quicker on anything lumpy or fast downhill and you'll stay fresher for longer. The tyres, geometry and ride position differences are the deciders.
