I am new to this and was wondering.
I did not get 650b because of clearance, or fatter tires, that people usually get them for.
I just wanted a nice Rivendell road-ish bike and wound up with a great opportunity to get a Bleriot.
I really like it alot. The most comfortable road-ish bike I have ever sat on.
But the different tire sizing has posed some new challenges for me.
All were pretty easy to overcome, though. But it was wierd not being able to have tires/tubes and stuff at one's fingertips, like with the mega-available 700 tires and wheels. And the lack of selection with and without puncture resistance.
They should have a 650b forum on here for future 650b riders because there is alot a new rider could gain from exprienced users. Such as where to buy wheels/tires/tubes when no LBS has anything on hand.
Apparently 650b was picking up in popularity back on '06, but with only a handfull of tire selections out there, it makes me wonder if it is going by the wayside.
