No . its on a pista. the miche BB is fine. but i had a little more money to invest for BB. Ive only heard since it is dual adjustable it has a hard time staying adjusted haha. For the money its great. If my current BB fails ill probably try it out. But again the crank arms are solid. I got mine from a fellow BF member for 100 shipped. great deal chainring and all.

that is one more thing. they are 135bcd which pretty much means its miche track rings only or campy road rings. But the miche chainrings are wonderful IMO.
