[Closed] Expensive Stems - Waste of Money ?

Given that it'll be something you look at all the time just buy the fancy one!

I have a rental duo that I love the look of. I can't say it's any better than the cheap one I had on the bike when trying different stem lengths. It holds the bars and looks good.

There isn't much difference in manufacturing costs on any stem really so I guess it's just paying for the name.

Like a Hollister coat compared to primark!!!

Funnduro stems are good in my opinion, Cheap and come up lighter than more expensive stems.

I love you stem

Stems are an interesting one. Mid tang are often forged and high end machined. Gram for gram, forging would give a better stem, but machining looks cool.

If you buy a really cheap stem, you can often feel some flex in it and you definitely don't want that. But that's on OEM stuff on cheap bikes, whether that's an issue with aftermarket stuff I'm not sure.

So whilst I wouldn't spent hundreds on a stem, don't [i]completely[/i] disregard its importance.

It's not just cheap stems that flex...

When i changed from a Truvativ stem to an Easton Haven 6 years ago, i noticed a massive difference in stiffness. Especially when riding up short sharp techy climbs and you're pulling hard on the bars. It's something i would never have thought would make much difference before changing,but it does, night and day.

My FS came with 780mm 35mm bars which I changed for 800mm.

I then got my HT that came with 760mm 31.8mm bars.

I want to put the 780's on the HT so new stem time. Could buy a cheap one that would absolutely do the job but instead Santa is brining a Hope one. Why? Because blue and toys.

So how much flex can you feel in a 40mm stem?

Just had exactly this dilemma after cracking my renthal stem. £30 for a perfectly functional, light Funn stem or more than double that for some fancy laser etching. It's a no brainer, Hope it is.

I hope not I’ve just ordered this:

I reckon flex may be a factor when it comes to roadie stems, and I'd probably spend more on one of those.

But I doubt you get much flex on a 25 quid 50 mm raceface stem..or any stem that length for that matter. That said I have a thompson, simply because I'm a tart.

So how much flex can you feel in a 40mm stem?

This ^.

40mm Brand X on my bike. Works just fine and cost about £15. There are many better places to spend a bit extra on, e.g. shifters/rear mech or decent compound tyres.

I'm a stem snob. Can't help it...you see it so much, you may as well get a nice one.

I'm' clearly not enough of a tart as I look at a Funn stem and think it's quite fancy.

Funnduro 45mm are in the CRC sale just now for 25 quid or so.

Because blue and toys.

Red ones are the fastest, but... "Always bet on black" says the Snipester in Passenger 57, so what to do??

Surely looking at one's stem is a recipe for discrashster??

Given that it'll be something you look at all the time just buy the fancy one!

I don't think I ever look at my stem when riding...

If you buy a really cheap stem, you can often feel some flex in it...

Sure you can... 😉

Red with a bright orange frame? 😯
No point in black as it wouldn't match my hubs.... Or new brakes. 😳 😆

[i]Extralite is the stuff of my childhood dreams[/i]

Not wishing to appear negative in this season of goodwill etc, but Extralite stems have been known to break spontaneously. Just too much material taken out.

Edit: just done a quick search and I think that was on an early design.

Running On One El Guapo Outaw that I picked up cheaply on sale but listing after new Pace stem. Wouldn't do the job any better but it's pretty.

I've got a Funn stem on my proper bike, it's only 35mm and I very much doubt I would ever notice any difference if I bought anything posher.

I've just put one on my new hard tail too, with £25 Funn bars too. Seem to do the job well enough.

Looks alright to me (steerer needs a bit taken off though).

They have become a bit of a fashion statement. Prices reflect the fickle nature and perceived disposable income of the customer base.

Very rarely/never have I heard anyone complain about a stems performance other than when it's not the right length/height to suit an individuals ergonomic requirements or it's faulty. Soft bolt heads or the clamps being machined slightly out of spec seem the most common. Oh and people stripping the threads or rounding the bolt heads 🙂

If you want an expensive one (usually for aesthetic reasons) it's your choice. The vast majority of cheap stems are perfectly adequate though.

Getting the right length is more important than stiffness imo.

😀

Hmm. I just spent £15 on a Brand X 40mm one.... I really can't see the point in spending more than the minimum on stems.

I've never really noticed any functional difference between stems, from 40mm to 90mm, very cheap to quite expensive.

Matching Thomson stem and seat post was nice on my last bike though......

Rental Apex on the fork steerer side by any chance?

That looks an awful lot like a Funnduro!

I've got a Funnduro and they're a nice stem if you need a low stack height. The only issue with it I've found is that the steerer bolts need cranking pretty tight as I've had the bars spin whilst riding a couple of times when torqued 'normally'. The clamping area is pretty small due to the low stack height design.

So how much flex can you feel in a 40mm stem?

Just how much force would you need to apply to the bars in order to flex a 40mm stem?

There must be some awsum dudes out there 😉

Get one that looks nice, matches the finishing kit on your bike.

No need to spend more than about £35 or £40, plenty of decent options from Funn, Ragley or secondhand.

Can't tell the difference in stiffness between Funn and Hope when I've swapped 45mm to 35mm length on the same bike.

That's what I think as well. On my mountain bikes I like to "tune in" with the stems (length) until I'am really happy with the bike.
Means: fairly low cost stems. Recently RITCHEY.

Problems I had with bad designed stems: if the clamping to the fork-tube isn't good the headset bearings loosen up. Adjusted the bearing play, torqued the stem to spec and after 2 weeks the bearings were loose again. This stem was too cheap...

Short stems and "flex": doubt that somebody is able to feel the difference...

yes, they are a waste of money but so are a lot of products we buy because of their colour or name. I got my spank stem for £25 in a CRC sale.

Thomson bars
Thomson seatclamp (fitted when I changed frame and the Thomson was the only one I could sort out quickly)
Nukeproof stem........had to go 😐

but so are a lot of products we buy because of their colour or name

Speak for yourself.

Some of us don't pay more for things in a certain colour and definitely not to have a specific brand name on our bike.

I have a 50mm sunline v1 stem on my Stiffee, bought it in the CRC sale many moons ago.

I tend to decide on colour, look at which ones i like then get one that's on sale.

Of course ahead stems don't flex enough to be able to feel it. Any flex would be in the bars and the wider bars get the more this would be noticed.

Let's pretend they do flex by say 1-2mm, how could anyone ever feel that?

All of last year I was using a 90's track bike with a quill stem. Now that did flex, you could actually see it. Didn't make any difference to riding though.

There isn't much difference in manufacturing costs on any stem really so I guess it's just paying for the name.

This isn't quite true, CNC machining from billet is quite a bit pricier than forging - and even basic CNC'd stem prices reflect this.

The problem for me was that I could either get a Brand X stem for a tenner (10.99 perhaps) or a Renthal stem for £70 and they weighed about the same as each other (cheaper CNCd stems were much heavier - and whilst on its own it doesn't matter, it all adds up when you have an entire bike with parts that each weigh 50 or even 100g more - which is a massive amount on something as small as a stem, really)

Funnduro here fitted to my 29er.
Wouldn't want it on an actual enduro bike though as it seems too light and twists/flexes ever so slightly I reckon.

Eitherthat or my titanium bars are giving me extra comfort ;d

I'm not saying everyone should buy £100 stems, but at least look for one from a company with some quality control or give it a good check over yourself and go at it with a file if needs be.

I go through stems as I like to adjust bike fit. I've had a number of cheap roadie stems with vaguely Italian sounding branding; a couple of Truvativ; I've had On One and recently a Planet X one - all less than £20.

The Truvative ones look the part - nicely anodised and finished - except for the white one which was painted and has started to corrode. The On One looks top notch for a machined stem tbh, as do the bars which were similarly cheap as chips. The Planet X one though is painted and looks cheap. But it was £8.

On my Heihei I had a Syntace F99 stem, in which 99g refers to the weight. That was 105mm and it did flex. Not up and down, and it wasn't noticeable in use, but I could twist it by pulling on the bars stationary.

I love these:

I did notice a big difference in stiffness between a cheap carbon cycles alloy 65mm stem and a 50mm Renthal - but that's no surprise when you compare the shapes of them.

I bought a nice RaceFace stem here some time ago for about 20 quid. It looks awesome.

Did I feel any difference when it replaced a Merida-branded one on a bike? Not at all. But it looks awesome.

I wouldn't buy it new for its full price though.

I had an old Ritchey stem that didn't feel quite right. I don't think it was the stem itself flexing, rather the pissy little face plate that had hardly any contact area with the handlebars.

Stems are an interesting one. Mid tang are often forged and high end machined. Gram for gram, forging would give a better stem, but machining looks cool.

Syncros MegaForce is forged rather than CNC'd, they're a great wee stem. Stupidly high RRP but you can get them for around half online, and they have a 10 year warranty.

I baulked at price of new mid to high end stems too 🙁

Secondhand Thomson £40 like new job done 🙂

I like a nice stem. Thankfully used ones are just as good so eBay will eventually turn up a good deal.

Had a Kalloy Uno on my road bike, it was very light and very cheap, but it just doesn't look as nice as a Thomson and I'm not afraid to admit I like my bikes to look good (to me at any rate).

RSP do a nice 35mm 'Trail' stem for about £25. Only the faceplate is branded so shouldn't offend too much.

Funnduro here fitted to my 29er.
Wouldn't want it on an actual enduro bike though as it seems too light and twists/flexes ever so slightly I reckon.

They're OK on a full enduro bike, but the Funn Strippa is slightly beefier and the same price.

Bike Monger was flogging Crank Bros ones for £40. They looked quite nice, might be worth it for cosmetic reasons. I do need to change the one on my Salsa - the white doesn't look great and like I said it's corroding.

Hmm.. Salsa do stems.. I wonder if it would look cool or just like cheap OEM by matching the bike?

Secondhand Thomson £40 like new job done

Thomson reckon the face plates of their stems are a consumable and need replacing every so often.

The 130mm stem on my road bike flexes like a MF when I'm sprinting, and it's a fairly nice one (high-end Deda).

I'm neither a sprinter nor very strong, so god knows what the pros manage to put theirs through.

This is what I've got on my current bike, it's quite nice in the flesh, the graphics are more subtle than the photos suggest, and you can't see the face plate when you're riding!

😆

Things are so nice and peaceful over here on the bike forum aren't they? A nice discussion about stems 🙂

When i changed from a Truvativ stem to an Easton Haven 6 years ago, i noticed a massive difference in stiffness.

I get excited when I look at my Easton stem too.

So how much flex can you feel in a 40mm stem?

Depends if you know how expensive it was.

I just replaced a very cheap Pro with a Renthal and it made no difference whatsoever. Except that it'll be a wee bit easier to swap 40 and 50mm, which is why I got it. Otherwise, it's very easy to make a decent stem.

I always love the Thomson thing- people say it's worth paying extra for quality, and you say, why do you think it's quality, and they say "because it's expensive". Thomson make shite stems. The bolts are too small and the faceplates routinely crack, they're literally the only manufacturer in the world that thinks faceplates are a consumable. They're not even especially light.

You can also buy bad cheap stems too of course. But if you're going to buy a bad stem, why make it an expensive one?

OTOH, one of the magazines reviewed the exact same stem, one branded Answer and one branded Superstar, and one of them was impressively stiff and the other was noticably flexy...

I didn’t necessarily feel 31.8 was flexy but my first 35mm setup happened because it was in a sale (so cheap) and the right colour. 35 was noticeably stiffer as a pair though - although I’d tend to point the finger more at bars than stems for this.

I used to like a nice stem but ended up with a Brand X one on the current bike. I can’t tell any difference from the Spank or Hope ones I used to have and I really like the fact the X is rather plain. Each to their own though and if you want some shiny shiny I say go for it.

STW became so much less annoying when I bookmarked the bike forum instead of the main forum! 😉

The consumable Thomson faceplates is madness. I know my Hope stems were rather expensive but I like them, they just work. I'm sure many cheaper stems would work well too but in the scheme of things the extra cost matters little as I change bikes infrequently. I have a Raceface stem on the other bike which doesn't look as nice but it too doesn't slip or creak or flex. My Renthal Duo did creak which was infuriating!!!

Back to the original question, there not a waste of money if you don’t think they are. They may not perform any better but nice things are nice so if you want one, they’re worth it. If you are happy with a cheaper one then cool.

The other thing about nice stems, bars, saddles etc is that in the grand scheme of bike things they’re not that expensive. Can I afford gold eagle stuff? No. Can I afford XTR? No. Can I afford a carbon frame? No. Can I afford fancy trinkets up to about £150? Yes. The end.

Jamesfts: yes, exactly. New bike build, just checking all the bolts, decided to just nip up the steerer bolts a touch...
I reckon a quarter turn less would be about right.

I did notice a big difference in stiffness between a cheap carbon cycles alloy 65mm stem and a 50mm Renthal

I think it was one of these:

vs one of these:

[img] [/img]

Obviously quite different designs. I don't know the wall thickness on the first stem but the 50mm Renthal weighs 139g and the 60mm Carbon Cycles 157g. Can the extra mass of the latter add enough wall thickness to make up for the smaller cross-section's reduced torsional stiffness?

My head says Brand X - My heart says Gammut

I best stay out of this after spending nearly a ton on Chromag stem...

(Chromag frame means Chromag bars and stem are mandatory).

Bloody lovely though...

Jesus that things ugly. Can't see the point of and expensive stem for a modern mtb when it's only 35mm in length. Still worth getting a decent one for the road where paying extra gets you a better stiffness to weight ratio.

Odd to say but I still think my fav stems were the road ITM Millenium used by the likes of Mapei and Lance. Off road Easton used to make some cool looking stems. But in the new mtb world where they are just stumps of metal they all look ugly and function similarly.
