[Closed] Lighter road wheels?

Second hand Giant slr0 30mm wheelset(rim brake) I got set £400 few years ago. Around 1350g and been fault free since.

Or farsports will do you wheelset for that money around 1400g

Hunt Aero Light Discs are ~1500g, cost ~£400.

If it's still available, that Prime 50mm carbon disc set with tyres for ~500.

Hindsight is a wonderful thing, but even though I usually like beasting myself up hills, I wish I'd thought more about aero over lightweight.

QR and rim brake? If so, get on eBay and look at some top end wheels from 10 years ago - some Dura Ace carbons or something. Could get them at a very reasonable price

I’m sure you know, but be prepared to be amazed for the first ride or two then realise there’s not much difference in reality.
On my winter bike I went from 1800 gram wheels down to 1500 grams, realistically no real difference. Hills are still really hard! I went from a heavy set of 40mm deep to 37mm deep, the 37mm deep are wider internally and are designed for 28mm tyres and above.
If I was looking at a 500 budget it’s the Hunts for me, but I’d be tempted to save a bit longer and go for deeper rims. Prob the Hunt 40/50 at 1458 grams.
I’ve just bought a new Trek Emonda, I’ve gone aero as well as lightweight. Comes stock with 1450g wheels, I’ve also bought a pair of 1600g 60mm wheels. Aero is king! I have no issues with lightbicycle wheels, but I personally prefer to have someone UK based to deal with.....I know the wheels are all made in Asia, just in the event of a warranty I’d prefer to be dealing with someone in the same time zone.

Prime aluminium jobs for less than £300 will get you @ or below 1.5kg. superstar components similar too. Keep using the others till bearings go or buy early and keep as a spare I suppose.

It's not for hill climbing purposes, it's because I miss that extra snap when stamping on the pedals. That's all. Silly way to spend money, but I haven't spent it yet!

Forgot about Hunt. Whilst looking for LB rims I had a look at their full wheels and they are pretty light and cheap. Ok so there's going to be import duty but still a good deal.

Oh and they would need to be disc and bolt through.

It is hilly where I live, but I suppose a certain amount of aero is goign to help me cover miles (a bit) which is another thing that I find a positive, probably more than anything else really. LB 30mm rims are only 20g heavier than their shallowest ones.

Light wheels feel nice, aero is faster.

I'm not exactly fast but ride solo mostly and dgas about times. Lightweight for me.

I wonder what the real benefit of aero is in group rides, and don't see it all for leisure riders.

"I just did my normal ride 1m faster!"

- "You just spaffed £500 on aero wheels"

I can think of plenty better ways to spend £500 than on incrementally faster bike rides.

Just riding along worth a look as well, lots of options.

“I just did my normal ride 1m faster!”

That's obviously pointless - but how much faster is it? Road riding is fairly dull, so changing the scenery quickly and the sensation of speed both make it interesting for me at least.

I mean - why bother spending any money at all on a bike? Why not just stay home, right?

1780 - 1400 = 380 grams.

All up weight?
85 kgs(you) + 8 kgs(bike) + 1kg(water) + 3kgs(clothes and shoes) + 1kg(phone, keys and shit) = 98kgs.

4% weight saving?

I've been there and done this and it doesn't translate into anything worthwhile other than less money to spend.
Get a skin suit.

I’ve been there and done this and it doesn’t translate into anything worthwhile other than less money to spend.

I too have been there and done this. I'm not new to cycling. I like riding light wheels, you may just have to deal with that fact.

Also, if you factor in the reduction in angular momentum required when accelerating out of a turn or from lights etc, the difference between light and heavy wheels is a lot more significant. And this is what you feel when riding a bike with light wheels.

When I wanted lighter road wheels I went to Superstar Components.

I got a pair of road wheels that weigh 1490 grams (I checked when they arrived) for £225 in one of their sales.

They're rim brakes and QR but they've been faultless and I would buy again :o)

Got 2 sets of Just Riding Along road wheels. They’ve been faultless and easily the tightest wheels I’ve owned.

£390 gets you a pair of 1440g ish Lark Lights.

Light wheels are ace and make a huge difference to the feel of a bike IME. There’s nothing like the way a pair of slinky wheels accelerates - makes the bike feel alive. I love getting on the summer roadie after a break, it just picks up so nicely.

if you factor in the reduction in angular momentum required when accelerating out of a turn or from lights etc, the difference between light and heavy wheels is a lot more significant.

I fully support your efforts, but just for amusement could you quantify this?

I was a road racer for a good few years and learned to be somewhat cynical when this kind of thing crops up.

Having just performed a similar exercise. I can wholeheartedly say it's worthwhile. I've just replaced some perfectly good Pacenti SL25 rims (450g) with some slightly wider and a little lighter Nextie carbon rims (350g). So that's a grand total saving of 200g on my already lightish 1670g wheelset. I bought these particular rims in art for the weight, but also as they had an almost identical ERD, so I could re-use my CX-rays.

Same tyres, same hubs, same spokes, same nipples on the same bike, literally only the rims have changed. The result is a night and day difference which is mostly positive. The bike feels so much more nimble than it did, faster to turn, faster to accelerate, just a lot livelier. Far closer in feeling to my UP. I'd never have guessed that 200g of rim weight would make such a difference, and in truth, it probably isn't just the weight. The carbon rims are just that much stiffer. For the most part this is great, but if you accidentally hit a pothole, by goodness it's a big hit.

Was it worth it? I got into this expecting to pay £175 to upgrade and in the end spent a little less. I think it was worth it.

They're on my commuter 🙂

I fully support your efforts, but just for amusement could you quantify this?

I can't be bothered to do it again but the difference on a windy MTB course where you have to brake and accelerate out of sharp corners a lot was equivalent to about 30W extra.

I'm not claiming that light road wheels make you loads faster. All I'm saying is that it gives a pleasing sensation. And pleasure is the only reason we do any of this, isn't?

I agree and I'm not trying to be an arse, honestly.

It's less prevalent now but there was a real glut of 'I've lost x hundred grams off my wheels and it's sooooo much faster i can't believe it' a while ago.

The thing that gets overlooked is the actual physics; when you accelerate, you're accelerating everything. Not just the wheels but the bike, you, whatever is in your pockets, whatever is in your colon, your fillings, your socks and so on.

It feels different, and I agree is more fun.

What about Scribe? They've got some sort of super fast engaging hub.

1780 – 1400 = 380 grams.

All up weight?
85 kgs(you) + 8 kgs(bike) + 1kg(water) + 3kgs(clothes and shoes) + 1kg(phone, keys and shit) = 98kgs.

4% weight saving?

Isn’t it more like 0.4%?
Also a pre ride dump means the last item is no longer carried.

Isn’t it more like 0.4%?

Probably, I was having my tea while doing the maths!

GCN did a bit about light wheels over the summer. There’s a good clip on their site.

I felt a big difference when I changed my old 26" Mavic 719's to Stans Crest rims.

Less of a difference when I changed my Road bikes wheels from Shimano R501 to Hope/Stans Alpha wheels.

I put this down to the large amount of accelerations when riding off road compared to the general steady speed when riding on road.

Not very scientific, I know.

Very pleased with the set I got from Farsports, and the service from them was excellent.

Wide 30mm deep carbon rims, CXRAY spokes, brass nipples and DT 350 hubs. Went with the option to pre-pay the import tax so no potential headaches at this end.

I’ve been there and done this and it doesn’t translate into anything worthwhile

Not in terms of speed and maybe not worthwhile to you but could be worthwhile to others as it is something you can feel and if it feels nicer that is a good thing when riding for enjoyments isn't it?

I am going through another old bike stage and have changed to a steel track bike (quill stem and all). Bike weight went up by 1.5 kg but I used the same wheels and tyres and the overall feeling of riding the bike was very similar. Then I changed the tyres to something a bit lighter and the bike feels better than the overall lighter bike did and I like it more. Is that not worthwhile to me?

It feels different, and I agree is more fun.

That's all there is to it.

All the other 'go for a dump', 'carry fewer biscuits/less water', 'areo is EVERYTHING' bolleux just doesn't matter. If you enjoy the sensation of changing bits of your bike(s), that's all the justification needed.

For years weight (especially rotating weight) was everything, now it's aero. Is this real or just another industry marketing ploy/fashion? 29ers? Gravel bikes?

We all fall for it.

Nothing wrong with changing a near-1.8kg wheelset for a sub-1.5kg one.

For me that's the realistically attainable weight for what I'm prepared to spend, and there's no dispute (though STW might prove me wrong) that wheels (and tyres) have the biggest impact on road bike feel.

I managed to snag one of the last pairs of discounted Prime Black Edition 28s for £500 from CRC earlier this year. The new version is £750 - but has also shed about 100g now (1,404g claimed).

They are great.

You can't beat the feeling of riding a light, stiff bike (road or MTB); it just surges with every pedal stroke and is a joy to ride.

There are some pretty decent light aero wheelsets out there now, 50mm for under 1400g all at pretty reasonable prices (compared to say lightweight wheels at £7k a set).

First upgrade for my Orca will be some new wheels lightweight 50/60mm section.

You can’t beat the feeling of riding a light, stiff bike (road or MTB); it just surges with every pedal stroke and is a joy to ride.

^^This,every time.

I don't need new wheels as my Summer/good bike is perfect (for me) ,but as the world moves to disks I have noticed a lot of nice second hand rim brake sets on Facebook marketplace.

there was a real glut of ‘I’ve lost x hundred grams off my wheels and it’s sooooo much faster i can’t believe it’ a while ago.

Yeah I know, and that is clearly untrue from a Physics point of view. As said, it's easy to prove how little difference it makes to your overall times. I hired a bog standard Specialized Allez for a week in Wisconsin and did four or five rides on it. It was something like 27lbs which is massive for a road bike. But it was actually pretty nice to ride, really. I only noticed the weight when accelerating.

And I think this is a key point. It is noticeably harder to accelerate a bike that has heavy wheels. So each time you stop at traffic lights or whatever, and you stand on the pedals to pull away, if it feels sluggish it puts a bit of extra strain and fatigue into your legs, and you feel slow. You may not actually be slow, but it's all about how it feels.

It feels different, and I agree is more fun.

Exactly this.

For years weight (especially rotating weight) was everything, now it’s aero.

So I was poking around on Light Bicycle's site yesterday. Their normal not particularly aero rim is 385g, and the 30mm one is 410g. I reckon at that kind of weight penalty it'd be silly not to go for the aero one. I think you can have both can't you? I'm sure it's a really stiff ride, but then this must surely be mitigated by having 28c tyres at 60psi no?

I think you can have both can’t you?

Yep, Hunt do 44mm aero wheel sets at sub 1400g for just over £1k.

For years weight (especially rotating weight) was everything, now it’s aero. Is this real or just another industry marketing ploy/fashion?

Aero is definitely real but how much actual difference it makes for the average rider is probably overstated. For example if I go out for a 1 hour ride and was 1 minute quicker would I actually notice the 1 second per minute difference? I would say not.
Lightweight is also real, especially when riding uphill but again would I actually notice the few seconds saved, probably not.

As I am not racing and any seconds saved are irrelevant then I just get the bike I enjoy riding and if that bike being lighter brings more enjoyment then I would get that one.

Yep, Hunt do 44mm aero wheel sets at sub 1400g for just over £1k.

Ah but the LB rims were the same price!

Lightweight is also real, especially when riding uphill

I don't think it is particularly noticeable uphill. I think it's noticeable when accelerating.

I appreciate the feel of circa-1500g wheels vs circa-1800g wheels uphill, for sure.

Saw consistent improvements on Strava climb times as well, versus an OE wheelset on the same bike.

Lightweight
Well built
Nice tyres/ tubs

All the above worth considering when it comes to feel.

I don’t think it is particularly noticeable uphill. I think it’s noticeable when accelerating.

I wasn't referring to noticeable, I was referring to it actually making a difference, i.e. faster for same power.

Saw consistent improvements on Strava climb times as well, versus an OE wheelset on the same bike.

Interesting - what sort of climbs? Steep or shallow?

I’ve had roval slx24 for three years riding all seasons and doing about 4500 miles a year - super reliable, and they haven’t been touched. But, although I ride them tubeless, the bead doesn’t lock in very well ( this isn’t a problem with gp5000s as they go up so easily but IRC are impossible to inflate ). Also bought light larks from JRA recently for my wife and they are very impressive. They are not set up tubeless yet but there is a definite ridge on the rim so I think the bead will lock better than my rovals

All of the above arguments relating to aero, snappiness, acceleration, weight etc are massively outweighed by the fact that deep section rims look an awful lot better on modern carbon road bikes and to be fair, the vast majority of metal tubed bikes, unless you're on some retro lugged steel noodle tubed sled.

just look at the Tarmac SL6 Sport with 25'ish mm rims and the Tarmac SL7 Pro, irrespective of gainz, the one with the deep rims looks best and lets be honest, that is the important thing here

Interesting – what sort of climbs? Steep or shallow?

Both, shallower when I swapped OE for Ksyriums on the rolling terrain of Hertforshire and steeper when I made the same swap (on a different bike) in the Pennines & West Lancs Alps.

The feel is more on the steeps though, TBF.

irrespective of gainz, the one with the deep rims looks best and lets be honest, that is the important thing here

This is so true, this is what it comes down to. When I first got a road bike after spending decades on MTB the bike came with an 1750g wheelset, had 1550g Ksyriums, now have 1350g carbon all of the same depth. Between 1550-1350g it was almost imperceptible, slight aero and stiffness difference play as big a part as weight - Ksyriums were stiffer so climbed just as well as a slightly flexy 1350g and were about a third of the price.

The 1750g wheelset was slightly sluggish accelerating but not much in it when up to rolling speed. Ironically I was much faster on the 1750g wheelset because was training more and younger...bling just compensates for the natural power reducing ageing process...which isn't to say it doesn't have its place.

For years weight (especially rotating weight) was everything, now it’s aero. Is this real or just another industry marketing ploy/fashion?

They've run out of sensible and/or easy ways to convince us to spend money on lightweight, so now are marketing new exciting tech (aero, disc brakes) which just happens to be heavier, so of course now all the reviewers are pretending weight isn't important 😀

rrespective of gainz, the one with the deep rims looks best and lets be honest, that is the important thing here

Plus that woosh woosh noise when you stand up and put the power down. Nothing beats that!

They’ve run out of sensible and/or easy ways to convince us to spend money on lightweight, so now are marketing new exciting tech (aero, disc brakes) which just happens to be heavier, so of course now all the reviewers are pretending weight isn’t important

Just read Chris Boardman's biography and he details the start of the secret squirrel club and their use of a wind tunnel to understand actual performance gains and what they'd mean to times on the bike etc. It does seem that the full appreciation of aero vs weight is relatively new (in terms of the age of the bicycle).

Probably because you can feel weight (by picking up bike!) and lighter must be better, just common sense isn't it. You can't really feel if one frame is a few watts better than another one.

A lot of us also don't ride that fast so the aero benefit is not as great as someone who rides everywhere at 25mph.

The Hunt Aero lights on my BMC SS replaced a set of Shimano RX5. That was nerl 3/4 kilo saving by the time I has Conti 5000 tubeless on there.
Makes a decent difference on the hills with SS and of course if you are at all geared for allround riding the aero differences are low as you can't really spin fast enough.

I wasn’t referring to noticeable, I was referring to it actually making a difference, i.e. faster for same power.

I tend to think the subjective 'noticeable' trumps the objective 'measurable' in this case.

If it feels nicer, looks nicer and happens to result in being a bit quicker - all the betterer.

In a lot of cases 'we' (I) don't ride fast enough to benefit from the the x minute percent gains from aero alone. I'll quite happily lap up aero at 'proper' lightweight weights but not if it means sacrificing the feel of a lovely lightweight bicycle.

I rode a friends early Scott Foil a bit ago. It was very aero, heavier than my similar non aero lightweights and a very, very firm ride. So heavily compromised in 2 out of 3 important areas. It was an early model so a lot of those shortcomings have since been developed out.

Now we can have aero and lightweight, I just need to wait until the price drops to mid range (£4k gah!) as, I'm not prepared to pay £10k for the early adopters privilege.

I can think of plenty better ways to spend £500 than on incrementally faster bike rides.

Maybe you can, but really why do we spend money on any of this? Why aren't we just riding £30 old boneshakers made of straight lead pipes, since anything more than that is just frivolous nonsense? My threshold's probably about £400 for wheels, but then I'm tight 😀

I can think of plenty better ways to spend £500 than on incrementally faster bike rides.

I can't!

So many LOLs in these posts.

It's well proven that aero makes you faster and low weight makes hardly any difference (including on wheels)

Yet people think they can feel what is faster 😅

Does depend on the course, you'd make different choices for a flat road ride vs a tight criterium vs a hill climb event.....

If "you" means "footflaps" then yes, but if it means "someone who follows science" then no, unless the hill climb is steep enough.

Unless you have evidence otherwise...?

It'd make quite a difference in a crit - 1700g wheels vs 1300g. I follow science, in fact I have a degree in Physics.

The most interesting scientific question here though is one of psychology: why cynic-al is posting here apparently to try and start an argument.

Some science here

It’d make quite a difference in a crit

It probably wouldn't, really.
The trick to crits is not massive accelerations, it's being smooth and well positioned so you don't have to keep accelerating...

...and that flywheel effect from heavier wheels is a thing, as is the desire not to get your wheels killed when some nodder runs out of talent or some junior tries the inside line.

32 spokes, three cross...

molgrips I am just finding it funny how many folk appear to live in a world where the laws of physics aren't the same as mine.

Your own posts suggest your physics degree is long forgotten, already evidence against your last post for instance. And you seem taken in by someone's claim that Strava times mean that weight might matter more than it actually does - no power or even heart rate to go on - laughable.

Takes more than a physics degree, especially if you have heavy cognitive dissonance to deal with. Unless you want to show us how that 0.4% mass difference adds up in the crit, with numbers?

It doesn't matter. If having lighter/faster/shinier/newer/different kit feels 'better' to the rider, so be it. It doesn't need any further justification so long as kidneys are not exchanged. Bolleux to the science, not all decisions are data driven.

If it enhances your enjoyment, crack on. It could be worse, you could end up respraying your car wheels in your bedroom or fettling cutlery out of carbon fibre instead of riding... 😜

molgrips I am just finding it funny how many folk appear to live in a world where the laws of physics aren’t the same as mine.

No mate, that's not it at all. I'm quite aware of the physics, as I said. So I'm not denying physics, you just aren't willing to listen as we explaim our reasoning. You think we are claiming one thing but we're actually claiming something different.

I'm not saying it's going to make me loads faster. I'm saying it feels better to have light wheels. And I've explained why. I even included science.

Some science here

Well it's a decent piece from the scientist because he explains the methodology which is vital. However their test is limited and they only tested three scenarios. And they are implicitly talking about faster overall speed which is of course useful for racers but not necessarily for recreational riders.

For example, they tested a very long alpine climb which is dominated by steady riding, and presumably the data is from a very good rider. So the speed is probably pretty constant and the cadence is probably relatively high.

However, when I'm winching up a 1:4 in the Valleys, my cadence is pretty low. So between each pedal stroke my bike is actually.slowing down a bit. This means I need to add angular momentum each pedal stroke, and that momentum goes back into the whole mass of me and rider between the power strokes. So I'm thinking that each stroke is slightly harder if you have heavier wheels on a very steep climb at low cadence. I haven't calculated if this is offset by the extra forward momentum, but my feeling is that the biomechanics would be negative. But this is a question of feel. In that experiment they weren't able to account for rider fatigue.

And in any case, for us it's not about speed.

and that momentum goes back into the whole mass of me and rider between the power strokes.

Yep this is why physically lighter makes no difference from a rotating perspective. It's pure speculation how this might affect biomechanics. In fact I would speculate that since heavier wheels store more angular momentum they're more likely to smooth things out.

I agree though, lighter feels better, despite my head knowing it really isn't that much better.

I see it as much a question of Geography as Physics in this questions relevance to the cyclist, the Physics seems to show that inertial mass makes negligible difference to speed. That GCN vid uses Sa Colobra which although a meaty climb is very consistent and not that steep at 7% average, I wouldn't expect to see much difference in wheel weight there and aero advantage could still trump mass, especially for a faster rider who will be going up that shallow grade at a fair clip. If the geography you are riding in dictates that you're seeing 15-20% + gradients then this is where saving 200-300g in wheel weight seems to be most noticeable. Geography dictates that most riders won't encounter climbs that steep so often, but if you have them on your doorstep or are targeting a proper big steep mountain event then the lighter wheel can be worth it.

I agree though, lighter feels better

Placebo effect?

Placebo effect?

Mebbes, but once I swapped near 2kg wheels for 1500g ones, not really expecting too much & I was staggered how much difference it made to the bike ( a Kona Jake).

Just watching that GCN vid it seems clear that lighter wheels should feel different to heavier wheels, because they have less of a flywheel effect. So I’m pretty confident that molgrips is following the science.

Maybe it needs pointing out in caps that ITS OK TO BUY BIKE COMPONENTS THAT DONT MAKE YOU GO FASTER

There was a thread talking about the tipping point gradient of weight over aero on bikeradar in recent years and iirc, someone claimed to have a source that the tipping point was ~8% for "strong" riders and ~4% for mortals and MAMILs.

I can see why those figures might be so different, given the vast chasm of diversity in W/Kg output between pros and amateurs, as tangible aero benefits are supposed to kick in at ~15mph... Off the top of my head, I think I've only managed to climb any categorised climbs at 15mph+ once and that was ~2.5 years ago https://www.strava.com/activities/1758990655 , even though I love to regularly beast myself up climbs despite 4W/Kg+ being me on a very good day.
But up around the South Downs, it's basically a giant rollercoaster, so even if I've climbed at less than 15mph I and many will be able to go way in excess of that on the other side of the summit.

I've only just got back from work and I'm in no fit state to try and hunt down the thread this afternoon, especially given the horrid "upgrade" that forum had this year!

So you bought the bike and could have got a superior model through C2W doubling the budget to £3000.
But you kept the £1500 model and now want to spend £500 on betterer wheels
One of things manufacturers skimp on is wheelsets on lower model bikes
An extra £500 increase in rrp gets you better finishing kit.
An extra £800 would get better wheels and finishing kit.
You say its mot about speed, but want faster wheels to get between the climbs quicker so the boring flat bits are out the way quicker.
It also wasnt about speed or times and yet the first ridevout you sravaaaaa d it and got a load of pbs
So its all about speed and times
I do get that lightweight wheels accelerate easier, but theres also quality of bearings, stiffness and the tyre you wang on it to factor in

Go for lightweight, tubeless climbing wheels. The amount of time you will spend at a speed where a 60mm rim really comes into its own is minimal. Or just spend the wedge on a set of 404s or Enves and be done with it

My summer bike has Spinergy wheels and a strong colourway and random riders do actually comment pn how good it looks

Oooh, have you slept with any of them yet?

But you kept the £1500 model and now want to spend £500 on betterer wheels

The main reason for that was the difficulty in getting bikes. The Cube was in stock and ready to roll. Waiting a week was hard enough! And anyway it'll be a long time before I do change wheels, if I ever do. And by that time I'll have got used to the way the Cube rides 🙂

Another point about that GCN vid is that its comparing light non-aero wheels with heavy aero ones. It doesn't compare heavy non-aero wheels.

Go for lightweight, tubeless climbing wheels

What's light for a road rim then?

That's me in a nutshell 🙂

I’m not saying it’s going to make me loads faster. I’m saying it feels better to have light wheels. And I’ve explained why. I even included science.

Ah ok, I have misunderstood. I agree it feels better to have light wheels, that's why I have them and not aero.

In your 1/4 scenario, I really can't see a few hundred gm making a significant difference among 100kg or so of bike and rider. Sure it will feel lighter, particularly out of the saddle. Anyways it's a very extreme situation, and you should get lower gears 😁

I'd be quite tempted by 35mm aero since there's only a few grammes in it on LB's website.

I went for some LB45s on CK disc hubs recently and they were only 1.43kg for the set. Why have light or aero when you can have both?

But 35 and 45 aren't proper aero, I've heard?

Molgrips you should go for tubs, <300gm no problem.
