OSPW X for Shimano XT/XTR 1x12

The OSPW X System reduces friction 35-40% over stock pulley configuration. 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 without added drag.

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

Only compatible with 1X specific derailleurs.
