OSPW Aero ALPHA Replacement Cage

What Our Gearhead® Experts Are Saying:

"This cage is the right answer when your OSPW Aero system has seen enough miles to warrant a refresh. It snaps into a SRAM RED or Force D1 derailleur exactly as expected and gets you back to the friction savings and clean shifting that made the original upgrade worth doing in the first place."

When you've already committed to the efficiency gains of a CeramicSpeed OSPW Aero system, keeping that system in race-ready condition is the logical next step. The OSPW Aero ALPHA Replacement Cage is the purpose-built solution for riders running Alpha Disc derailleur pulleys who need to refresh their setup without replacing the entire pulley assembly. Designed to work exclusively within the OSPW Aero architecture, this cage maintains the geometric precision and aero-optimized profile that the system was engineered around from the start.

Compatibility is tight and intentional. Full V2 certification means the cage integrates cleanly with SRAM RED D1/E1 and Force D1 AXS V2 rear derailleurs running 12-speed AXS electronic shifting. Maximum cassette support extends to 36 teeth, covering the range that most road and triathlon builds demand. The cage itself does not introduce new hardware into the drivetrain chain but rather restores the existing OSPW Aero system to its original specification, preserving the low-friction benefits of the Alpha Disc pulleys and the clean power transfer that comes with a properly maintained CeramicSpeed setup.

For racers logging high mileage across training blocks and event seasons, cage wear is an expected variable rather than a surprise. Having this replacement on hand means downtime between a worn component and a fresh install is measured in minutes rather than days. It is the kind of detail-oriented maintenance that separates a drivetrain that performs at its ceiling from one that gradually drifts away from it.
