For me it's my fat *ss that makes me slow. There's a lot of reasons to do a 650B conversion. Speed isn't one of them. Good luck
I don't intend to do it to be fast. I want the looks, the feel and the ability to ride unpaved roads with more ease. I want it to be my commuter, light tourer and randonneur. But i must be able to ride reasonable fast without feeling like i'm on a slow, sluggish tank.
I'm half tempted to convert my new 87 Trek 400T Elance. If i hate it, i can always sell the wheels and brakes.
Any complaints about running the uber long reach tektro dual pivot?
