The OSPW Aero ALPHA v2 pairs the new ALPHA Disc composite-tooth pulleys and ADR (Advanced Derailleur Roller) bearing protection with the proven aero-cage profile, giving TT and triathlon riders running SRAM AXS both watt savings and aero gains in a single upgrade.\u003c\/p\u003e\n\n\u003ch3\u003eWhy riders choose OSPW Aero ALPHA for SRAM AXS\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eStructural aerodynamic cage reduces rear-derailleur drag by up to 60%.\u003c\/strong\u003e The derailleur sits in turbulent air right behind the leg, where standard cages give back free watts. On a flat 40 km TT the aero cage hides real time at the same effort — exactly where AXS-equipped TT and Ironman bikes are decided.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOversized 13\/19 ALPHA Disc pulleys, 35–40% less drivetrain friction over stock.\u003c\/strong\u003e The composite-tooth ALPHA Disc profile rolls quieter and smoother than aluminium teeth, so drivetrain efficiency stacks on top of the aero gain — your AXS bike accelerates and holds speed with less effort on every flat and rolling section.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePatented ADR technology bearing protection.\u003c\/strong\u003e Standard pulley bearings die fast under race-day rain, sweat and pressure-washing. ADR seals out water and grit so the system stays silent and free-rolling through every race block instead of going crunchy mid-season.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTuned for SRAM AXS shift dynamics.\u003c\/strong\u003e Generic aero cages can throw off SRAM's electronic shift timing. The v2 cage geometry is matched to D1\/E1 derailleurs so shifts stay crisp and consistent across the cassette under race load.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePlug-and-play install in under 15 minutes.\u003c\/strong\u003e No chain length change, no AXS recalibration — bolts onto your existing Red or Force D1\/E1 derailleur with the supplied eTap AXS tool. Fit it the night before your A-race without any drivetrain anxiety.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e2-year warranty, 60,000 km service interval.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete OSPW Aero ALPHA system for SRAM Red\/Force AXS (cage + 13\/19 ALPHA Disc pulleys, pre-assembled)\u003c\/li\u003e\n\u003cli\u003eTool for eTap AXS\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eCeramicSpeed decal\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: 116925\u003c\/li\u003e\n\u003cli\u003eNet weight: 118 g\u003c\/li\u003e\n\u003cli\u003ePulley material: Aluminium with composite ALPHA Disc tooth profile\u003c\/li\u003e\n\u003cli\u003eDiscipline: Road, TT and Tri\u003c\/li\u003e\n\u003cli\u003eDerailleur: SRAM Red AXS D1\/E1, Force AXS D1 (12-speed)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eIt is not possible to add ALPHA Disc pulleys to a previous-generation OSPW Aero cage — this is a complete updated system.
