Profile No-Boss Cranks are now available for fixed gear bikes. These are intended for use with a spline drive sprocket or spider, as there is no way to attach a standard BMX chainring.
This is a complete crankset with English BB, Gun Drilled Hollow 5 1/4 or 5 5/8 CrMo BB spindle, Profile No Boss Race Crank arms, and the Profile crank installation and removal tool. If you order the Internal BB for 68mm BB, you will receive the shorter spindle, if you order the Mid BB, you will receive the 5 5/8 spindle
Included in the package is an assortment of spacers. Most bikes will not need all of them- you should use as few of them as you can get away with and still have decent clearance between the arms and your chainstays.
Also available with Outboard Bearing Bottom Bracket. The Outboard BB will be shipped with the 5.625\\\” GDH Spindle. You should also purchase the BMX Outboard BB Spider, which will improve your chainline.
