Alex Rankin asks the above question and more as he questions various players in the industry about the industry's sudden embrace of 27.5/650b tire size for mountain bikes.
Our own Jim Porter was one of those interviewed and he did a decent job giving a micro-history of 650b. For the record we have no frickin' opinion whether 650b will/should replace 26". That was one of the 'other guys'. (Interviews took place at Eurobike. Via Pinkbike)
Eurobike did have on display a ton of 27.5 frames and components. There might be more 650b offering in Europe than in the USA in 2013. Schwalbe, Maxxis, Scott, Rotwild, Ghost, Silverback, Rocky Mtn., Rockshox, SR Suntour. We are kinda pissed that RS is releasing their 650b fork with a tapered steerer. I guess we have to steer our B-Side customers toward X-Fusion.
