Photo: Brook MacDonald, InstagramNew Zealand's Brook MacDonald just uploaded a photo of his prototype 650B wheeled Trek Session race bike, the machine that he'll be aboard for this weekend's National Championships in Rotorua. While there's no real concrete info at this point, it's clear to see that the bike employs the same ABP and Full Floater suspension layout that the Session has used in the past. Comparing the frame to the current production model does seem to show some slightly different shaping in the carbon tubing, however, and it is very likely that this prototype sees different geometry to work with the larger wheel size when compared to the standard 26" wheeled bike.
It's also worth pointing out what looks to be a more developed version of the prototype FOX RAD-spec shock that we
spotted at last year's World Champs event. Its adjusters are much cleaner than that early version, and the shock's piggy back also appears to be quite a bit shorter as well. The fork is a FOX 40 Float RC2 with 650B compatible lowers with seven millimeters of added offset compared to the 26" model in order to correct for proper trail geometry, and it's likely that its internals have been given the RAD treatment that includes different valving, lower friction seals, and Kashima coating applied to the damper and air rods.

Or alternatively just, grow up/ wise up/ or shut up
For me - and neg. prop and mock away - there was a definite turning point in how much I enjoyed mountain biking when I knew my brakes would stop me, I could click right to the next gear, I wouldn't be beat to a pulp by a rigid fork. Oh, and my tires were big enough and sticky enough to offer reliable traction. It was in '99 on a Schwinn Homegrown HT…bass boat green paint for those old enough to remember those bikes.
25mm(ERD) is not microscopic- no matter if you are a nuclear chemist or a kintergarder.
AND:
A 2.5" tire adds the same to 26' rims as it does to 27.5" rims.
All the art majors on PB...

Do you decry every one running tires bigger than 2.1 cos we didn't run those stupid big tires back in the bad old days, Smokes and Farmer Johns for life y'all. Hand back your suspension, your disk brakes, your lock on grips, and your moto shorts, cos progress is bad.
Lets all roll Model T's to the races and pull our penny farthings off the racks and go carve some berms and rail some roots
I am indifferent to all this wheelsize hooplah. I ride a 26" DW DHR and am currently building a 26" Iron Horse 6 point(with flat pedals too...gasp) as my trail bike. I've never ridden any of the bigger wheel sizes but don't feel the need to either. I have fun on my 26s and I'm sure I would have fun on the bigger sizes. The majority of the world cup circuit is privateers, and I imagine the majority will remain on 26. The well funded teams and factory teams will run whatever they feel suits the particular course they are racing that weekend.
26x2.5 is 27.2in (690mm) in diameter
650b x 2.5 is 28.1in (715mm) in diameter
so you'll get your wish when they start making 650b x 2.7 tires...
A 26" wheel is nowhere near 26" in diameter.
Now I'm not stopping anyone from buying them, most of the people buying them at the moment is for fear of not being able to resell their bike in a couple of years...
Get over it peeps. Ride what you've got until you need a new bike. Then buy what you want from whatever's available. Your whining isn't going to stop the market dynamics. Have fun! (BTW, I bought two Knolly 26ers last year, so I should feel threatened by the 650b juggernaut - but my bikes are fun, so I don't care. When it's time to replace them, I'll choose from what's available and I will enjoy it).
Second it was an observation I remember the review vaguely which I thought I pointed out in my original statement!
Yes there may of been holes in it but surely every other review / comparison has shown advantages of the wheel size, at the end of the day it's only you who can decide if it's right- but ultimately if it's quicker down the hill teams will run it
Change is the only constant in life.
You don't like 27.5" or 29" ? Good - you live in your little security bubble, whilst I take the advantage of evolution.
ps: firstworldproblems
Top 3 running 650b! Surely that says something
The rest of the cycling world: "I test rode that 650b carbon bike with carbon wheels. Wow it rides great. I'll take two- one for me and one for my wife!"
Who do you think they are responding to? I'll even give you the answer: both of you, because money keeps them in business!
26 is perfect and if we keep f*cking with it we are going to ruin dh/fr mtb
