I dunno about the whole 650B thing
I see no advantage to it (least not for FR or DH)...I mean seriously...Do we really need another standard.
Do bike shops really have to now worry about stocking yet more parts?
OK look at DH and think Moto....Moto bikes have not changed their tires to anything bigger in like forever.....They still work great..
Why go with a bigger wheel? So you side load bearings faster? Apply more stress on the frames? Make the bikes react slower?.. I dunno about you but on longer travel bikes I can see issues...
Add to that, What are the wheel spacings are they going to think of running?
Don't get me wrong...I am all for new ....But sometimes adding yet another standard can be silly...I see the great advantage a 29er has over a 26er for XC. But with everything that already is...Do we need it? Think about how hard it already is ordering a headset for example. Or a set of wheels...With wheels there already is confusion with 135,142,150,157, then axles. QR9, QR10, 12x135/150. And that is just the rear...Qr9, 15QR, 20mm, (24mm and 25mm for some) have been around.
I think to a degree it is just something to be different.
No applause please!! Just Money..Thank you..
