CeramicSpeed OSPW Aero Alpha System Shimano 9250/8150 - Coated Races Aluminum Pulley Carbon Cage BLK

Engineered to cut drag and improve drivetrain efficiency, the Aero ALPHA system translates power into faster accelerations and steadier climbs.

Aesthetic pinstripe graphics add visual motion while the carbon cage and composite pulleys optimize weight and durability.

Who is this for?

Performance-minded riders who chase marginal gains, triathletes looking for every aero advantage, and serious club racers upgrading an Ultegra 12-speed build will appreciate the precision, durability, and clean setup this system delivers. If you want smoother shifts, enhanced longevity of the chain, and a quieter drivetrain on long rides or sprints, this is for you.
