    Something like a 118 Will most likely fit. However, what I would do, would get the Try All ISIS 128mm bb (also a 68 shell), that way if you every go Koxx or Coust, you will not have to worry about a new bottom bracket (or any other frame for that matter).

    are you sure that there will be enough room for the freewheel ( i dont mean in terms of chainstays, but interms of bb shell) with a 113?

    i had a 113 with a WI freewheel on tryall cranks and that shit did not fit. 118 works. this was on a zebdi....dunno about a b26, maybe our gay bikes have similar bb shell sizes. :p


    this post probably helped 0%. :dunno:

    did the freewheel hit the chainstays or did it hit on the bottom bracket shell?

    it hit the bottom bracket shell, and would eventually unscrew it! :rofl:

    no problems with the chainstay clearance

    b26 uses 118mm bb length (I used 22t ring so u may be able to go smaller.. but incase you want to use normal freewheel)

    I used a 113mm on square taper and chainring hit the chainstay :(


    Hope this helps
