CeramicSpeed OSPW X for Shimano XT/XTR 1x12

The OSPW X System for Shimano XT/XTR 1x12 reduces friction by 35-40% compared to stock pulley configurations. The lightweight, custom-molded carbon fiber cage ensures durability. This design allows the use of the same length chain as stock pulleys.

The 14-tooth upper and 18-tooth lower pulley profiles ensure stable chain retention while reducing drag.

The OSPW X System is developed, designed, and handbuilt in Denmark—and proven globally.

Only compatible with 1X specific derailleurs.
