CeramicSpeed's Oversized Pulley System frees up to 60% of the friction in your Shimano mechanical derailleur's pulley cage, leaving you with a savings of at least 2.4 watts. This incredibly smooth OSPW system was developed and handmade in Denmark using large 17T alloy pulley wheels that spin on ultra high-precision ceramic bearings. Every little bit counts when you're vying for the win, and CeramicSpeed makes sure nothing is left out on the road.
