As the fastest oversized pulley wheel system on the market, the CeramicSpeed Oversized Pulley Wheel System (OSPW System) has been developed to answer the riders’ increasing need for improved drivetrain performance.
The OSPW System optimises the overall efficiency of your drivetrain thanks to the extremely low friction of the CeramicSpeed Bearings and the unique design of the overall system.
Gravel Specific X-System
If there are Gravel UCI World Championships, if there are gravel bike-specific wheels and groupsets, then there must also be an OSPW system for such groupsets, CeramicSpeed thought. And anyone who's ever been addicted to speed on gravel roads will agree unreservedly!
As with all OSPW derailleur cages, the same applies to the X version: Larger wheels and ceramic bearings mean less friction and therefore higher speed. Made in Denmark means the highest quality. That's why CeramicSpeed also offers a lifetime guarantee on every coated OSPW X cage.
