Product Description

You can now use Shimano Hollowtech-II or SRAM/Truvativ GXP cranks in your BB30 frame thanks to these handy Wheels Manufacturing PF30 shims. This system is designed specifically for Shimano Hollowtech II or SRAM/Truvativ GXP cranks and are based on industry standard BB30 bottom bracket shells. They are easy to install and machined for exact fit. Shims press fit directly into BB30 bearings (6806), and you will need to have your bearings already installed. Sram / Truvativ cranks have a TAPERED SPINDLE (24 mm to 22 mm). Drive side measures 24 mm while non-drive side measures 22 mm. Shimano cranks have a standard 24 mm diameter on both drive and non-drive sides of the spindle.
