With all the bottom bracket standards on the market, Wheels Manufacturing has its hands full keeping up with necessary adapters. Its PF30 Adapter For Shimano makes the conversion from PF30 to a Shimano 24mm crank spindle a simple procedure. The assembly involves two reducer sleeves. These have been formed from solid blocks of Delrin, which is a polymer with high stability and strength. They work just like a PressFit, and once they're in place, you're able to simply slide your 24mm-crank spindle in place. The result is a perfectly tuned crank without creaks, shimmying, or extra play.
