[Closed] 650B the new 29 er's. Looks like the tides are a changing.

For those saying that there is no point to 27.5'' as 650b is so close to 26''. Have you actually ridden one? Thought not.

It's 3.5% bigger. Taking tyres into account. The actual size difference can be 7mm. Placebo effect.

I have.
Enjoy your thoughts 🙂

I.N.R.A.T.S

However, nothing has done more to worsen my opinion of mtb manufacturers and their marketing departments than the flogging of 650-****ing-B so soon after the 29er push

(I bet nobody else has said that, hey ? 😳 )

Can you also change the frame geometry?

Surely it changes every time you change the wheels. 🙂

I'm happy for 26" to stay around because when I'm racing and a guy inevitably bins it in front of me on his 26" I can just ride over him on my 29" without even feeling it.

Just as well, JCL, you obviously wouldn't be able to manoeuvre around him with those weelz 😆

Goal!

the fact that industry have been pushing it shows that there is something in it otherwise why would they bother,

For the last 2 weeks since I bought it. Fantastic bike. Really don't understand all the fuss about competing wheel sizes. Just buy a bike you like the feel of and ride it till your in fits of giggles. Repeat at least weekly.

Did you get that tracer buzz?

I really don't care what wheelsize people ride, as long as they ride.
Fitting big tyres to 26'' to achieve 27.5'' size with small tyres is missing the point completely. Rather amusing.

ive seen precisely 3 29er bikes, stoner had some abortion of a thing with rohloff and funny big wheels, mostly as he's odd, then saw a merican riding one round Cannock last year, and my neighbours just bought one because his friend told him too (and he got a cracking deal on it) I conclude that the death of 26" is massively over exaggerated, and hype of 29ers is massively over exaggerated as well.

Never even seen a 650...

ok - so how does anything being "bigger" actually make it faster?

Surely, to move one metre along tarmac or a dirt rod takes X amount of energy. And you have to move the wheel through a metre at the edge of the tyre.

So allowing for bearing friction, which is going to be very small, and maybe wind resistance, all wheels must be just as fast as each other, from a size POV.

I would guess wheel weight would make far more difference TBH.

Now, in terms of handling, 26ers are going to be more agile , 29ers more stable.
But that isn't going to stop the trade selling like a bastard !!

Remember you all ready have XC, AM, Freeride, Downhill, Jump, 4x.

Soon you will have a bike for each season ...

I have. The difference is titchy.

Thing is, the cost difference to switch from 26 to 650 is the same as to switch to 29er, but it's even harder to justify because the actual differences are smaller.

This is why I expect 650b to take over- the bike industry loves the pointless middle ground when it comes to standards and 650b is the 15mm of wheels.

Indeed 😀 currently flattening The Mendips with it. And avoiding looking at bank statements :-O

Good work. Green? Box has promised me a cabbie on his. I'll say hello if I see you up there. Do you ride with Nathan?

Green. Very, eye scorchingly, green. Nath specced and built the 275 for me, and did a brilliant job of it. He is really riding lots of DH so no not with him, tho he says he want to build a 275 of his own. Box is blown away with his Raw finish 275 but had a nasty prang on his second outing and hurt his knee so off the bike for a few weeks. He's pretty miserable about it so take a packet of hobnobs next time you go in shop to cheer him up.

It a bloody good bike. I can stop grinning this evening.

Gwinn just won the Sea Otter DH on the Enduro 29".

sea otter course is 2 laps of a disused velodrome isn't it ?

Gwinn just won the Sea Otter DH on the Enduro 29".

Yeah, look at that killer margin...

I mean the 29er, it just slayed the field! Considering it's Gwin, and Sea Otter (probably the most perfect 29er environment) it's hardly conclusive is it. In fact we're used to him putting multiple seconds into the field, not 0.01 of a second.

So, did the 29er slow him down??

Gwinn just won the Sea Otter DH on the Enduro 29".

Isn't that the course you called a joke?

Hmmm...

Despite reports to the contrary, Gwin was aboard a 26" wheeled bike, although he was spotted practicing aboard an Enduro 29er

So Hobnob, can you clarify if the 29er slowed him down? 😉

I don't think Sea Otter's that useful tbh. Then again I also don't think the results that the fastest riders in the world get necessarily mean a thing to us dobbers.

Probably did, hence why he didn't use it!

So, did the 29er slow him down??

I imagine so, yes.

Hob Nob - Member

Probably did, hence why he didn't use it!

Or, he rode a bike he's more familiar with or more comfortable with, regardless of wheel size.

Point is, a minute ago you were theorising that it might have slowed him down in the race, since he's the fastest man in the world and he only beat mick hannah by a .2 of a bawhair. But it didn't do that while sat in the truck 😉

They all have their pros and cons - any claim to the contrary is just marketing. Ride a 20" regularly and a 26" feels like a steamroller!

Why does there have to be a best?

What is the "best" mean anyway? The lightest, the grippiest, the stiffest, the one that keeps more speed, the one that allows the most generation of speed?

Why can't it just be nice to have all available, give all a go and work out which is best for our own personal riding styles/preferences/locations?

The "best" wheel size will inevitably vary from person to person.

I have yet to ride either of the new sizes.

I am 29r curious as for the rolling openness of the South Downs I could see the benefits (although I emphatically dont feel a need for one as my 26r never fails to make me smile).

650b just strikes me as likely to be too close to 26r so wouldnt look for one as a specific feature. That wouldnt stop me owning one if the bike I wanted was 650b its just it seems to be something of nothing excepting the pro/elite riders who may be able to make real use of the small performance gain over 26".

Or maybe Gwinn wished he did use a 29er and been faster! Complete speculation. A pro will be quick on any decent bike. I like my 29er and 26" bikes. Don't think I will be rushing to by a 650B though. Its just too similar to a 26" and another standard.

Politely, this is a mis conception. The lads, all on 29ers with me on a 27.5, were thrashing DH trails, squiggly singletrack the width of your palm, and microwave sized rock fields today. Box won a gravity enduro on one. Well designed big wheelers are just well designed bikes.

I might have said this before: This is engineering. There is no 'best'. All there is is the least bad balance of compromises for the specific application. And as we're talking about mountain biking, which is an incredibly diverse sport compared to road biking, then there's no reason for numerous different wheel sizes to not co-exist, just as forks and frames come in a massive variety of geometries, strengths, stiffness, spring medium, sizes and so on...

I ride a 26er MTB. Quite a lot my riding buddies ride 29ers, though far more are on 26. Most of those I regularly ride with don't change their bikes very often at all. I like the idea of 29er as a second bike for less agro riding (my agro riding being more about corners, jumps and drops than high speed rough descents - I'd totally get something like a Quarterhorse if I lived somewhere rocky) but I've been disappointed to notice the lack of mud clearance on them. And I like how short chainstays feel so I'm not sure how that can be solved!

650b may prove popular, it may not. In my opinion it's close enough to 26 that it really doesn't matter if one kills off the other or if both take a fair share of the market - by the time that happens I'm sure my current MTB will have been retired to an easier life. Much as I like using my LBS, I don't buy tyres there and that's the main scenario where too many wheel sizes is a problem.

Reckon 26ers have a very short shelf life now

Halfords sell up to 1 million bikes a year

The vast majority of those have wheel sizes no larger than 26"

Don't confuse marketing hype with real life sales figures

Don't confuse the UK with the rest of the world. The only 26" in my LBS are DH.

[i]I like Kimbers analogy of Betamax and 29ers.

Betamax was the best variant of video but VHS was the winner due to the larger manufacturers with the most money.

This was the best variant:

And one of the guys yesterday rode a 29er HT, the one bit of impressive stuff was were he rode up/over some heather, that none of the rest of us could manage (and he wasn't the fittest/fastest etc). It just 'steamrollered'.

But for me, as someone with about five 26" wheelsets and four frames...

Don't confuse the UK with the rest of the world.

Fair point - I'm sure your average Chinese or Vietnamese person isn't having the 29er/650b/26" debate. I imagine they buy the best bike they can afford that meets their needs.

...and I'd suspect your bike shop is a niche shop selling to the local 'specialist' market. Ask the owner how many bikes he sells a year and then decide if it's going to affect the global bike market (to use your point)

Daft question but... the dimensions we are talking about are all measured from the same point, outside of the rim?

seem to be plenty of 29ers riding xc round here this weekend 😆

One interesting comment that seems to have been forgotton is that almost all riders buy their bikes from a LBS. LBS will not want to stock 3 different sizes - that way too much stock and explaining to do.

So some of this imagined demand may not materialise just because the LBS has limited space and cash.

Well the North American market is the largest market for performance mountain bikes. The public here seem far more accepting of different standards if they provide a benefit so I guess that's why 29" are the majority of sales? The UK is stuck in the mud for some reason.

For fear of being wrong 😉

The UK has different conditions and a dedicated mountain biking community (with its own trails and events) that has grown up with 26ers. That's not to say there aren't all sorts of other bikes and events (cross, road) run as well though. We do suffer somewhat from the US pushing stuff on us without bothering to understand us. Just because the US does it doesn't make it right
