Description
OSPW Pulley Wheel Aero Alpha System For Shimano 9250/8150 - Coated Races, Aluminum Pulley, Carbon Cage, Black
The CeramicSpeed OSPW Aero ALPHA system for Shimano 9250/8150 derailleurs updates the fastest proven aero derailleur cage to include CeramicSpeed's patent pending ADR bearing protection and quiet performing ALPHA disc with composite tooth profile pulleys. Furthermore, a speed defying pinstripe graphic has been added for a splash of visual motion.

- The 13-tooth upper and 19-tooth lower Alpha pulley wheels feature ADR bearing protection that completely encloses the bearings
- This OSPW System has handbuilt CeramicSpeed coated bearings installed in each pulley
- Grade 3 Silicon Nitride ball bearings are 400% smoother, 128% harder and 58% lighter than standard steel balls normally used in the bicycle industry
- 4 customizable spring tension settings for optimal setup
