OSPW Aero ALPHA v2

What Our Gearhead® Experts Are Saying:

"I installed this on a race bike, and the drivetrain felt smoother right away. The reduced friction and quiet operation stand out, especially during longer efforts where efficiency matters."

We rely on the OSPW Aero ALPHA v2 from CeramicSpeed when optimizing drivetrain performance for road and triathlon setups where every watt counts. Designed to reduce aerodynamic drag and mechanical friction, it delivers measurable efficiency gains at speed.

The aerodynamic cage structure reduces drag at the rear derailleur, while oversized pulley wheels lower friction compared to standard configurations. ALPHA disc pulleys use a composite tooth profile to improve chain engagement and reduce noise, while ADR bearing protection enhances durability by shielding internal components from contamination.

Constructed with precision-machined aluminum and hand-assembled components, the system ensures consistent alignment and long-term performance. The design is engineered for Shimano Dura-Ace 9250 and Ultegra 8150 derailleurs, delivering a purpose-built upgrade for modern high-performance drivetrains.
