What Our Gearhead(R) Experts Are Saying:"I swapped this cage onto my SRAM RED AXS build after the original showed wear, and the whole system ran as smoothly as the day I first installed it. If you've already invested in an OSPW Aero setup, having a spare cage on hand is just smart racing."Race season has a way of putting every component through its paces, and even the most refined drivetrain upgrades need attention over time. The CeramicSpeed OSPW Aero ALPHA Replacement Cage exists to keep your investment performing the way it did on day one. Built specifically for OSPW Aero systems running Alpha Disc derailleur pulleys, this cage slots directly into SRAM RED D1/E1 and Force D1 AXS V2 rear derailleurs with full V2 compatibility, so there is no guesswork about fit or function. Whether a cage has seen a season of hard racing or simply needs replacing after a mechanical, swapping it out returns the entire OSPW system to peak operating condition. The result is the same low-friction, aero-optimized shifting performance that made the upgrade worthwhile in the first place.
