The Ceramic Speed 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.
