Wondering if anyone has tried to fit a 650b rear wheel on a Fluid?
there's no way, at least before '09 - tire clearance is minimal even with a 2.3" tire; unless you're running slicks you won't be able to fit bigger wheels. except i hear in '09 the stepped up the tire clearance. but why? run it the way god intended.
Any frame or fork that will accept a 26 x 2.6 will accept the largest 650B currently offered (Kenda Nevegal 2.35 or Pacenti Neo-Moto 2.35) just fine.
