Details
The CeramicSpeed OSPW Aero ALPHA system for Shimano 9250/8150 derailleurs updates the fastest proven aero derailleur cage to include our 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 OSPW Aero ALPHA cages have been updated to accommodate the ADR equipped ALPHA disc pulleys.
It is not possible to add these pulleys to a previous generation OSPW Aero cage.
