You have to use Tektro Oryx which has enough adjustment for it. If you do like this better, you may want to invest on a set of Paul MotoBMX.

In case you are those who believe lower BB height, you may want to read this. http://davesbikeblog.squarespace.com/blog/2007/2/21/bottom-bracket-height.html Ron On Feb 1, 8:25 am, Lee <leec...@gmail.com> wrote: > Oops, I just realized this bike may be going from 559 to 584.
