OSPW Aero ALPHA v2 delivers faster, smoother drivetrain performance
What Our Gearhead® Experts Are Saying:
"I’ve run this on a race setup, and it’s one of those upgrades you can actually feel at speed. It runs noticeably smoother, and the drivetrain stays quiet even under load."
We chase marginal gains wherever we can, and the OSPW Aero ALPHA v2 from CeramicSpeed delivers them where it matters most—right in the drivetrain. Whether we’re lining up for a race or dialing in a high-performance build, it brings efficiency and speed into every pedal stroke.
The aerodynamic cage design reduces drag at the rear derailleur, while oversized pulleys improve chain flow and minimize resistance. ALPHA disc pulleys with composite tooth profiles keep operation quiet, and ADR bearing protection helps maintain performance over time. Hand-assembled construction ensures precision at every level, giving us a drivetrain upgrade built for consistent speed.
