CeramicSpeed OSPW RS ALPHA — SRAM Force/Rival E1 AXS

An oversized pulley wheel system engineered for SRAM's mid-tier AXS derailleurs. The CeramicSpeed OSPW RS ALPHA for Force E1 and Rival E1 replaces the stock pulleys and cage with a hand-built, ceramic-bearing system that takes Rival and Force AXS bikes from solid-but-noisy to silent and efficient — closing the watts gap to Red AXS without the Red AXS price tag.

Why riders choose OSPW RS ALPHA for Force/Rival E1

Oversized 13T + 19T aluminium pulleys with ceramic bearings. Stock Force/Rival pulleys spin on basic bushings and bleed watts through chain bend and seal drag. Larger ceramic-bearing pulleys reduce articulation and friction so you save real wattage at threshold and your X-Range chain lasts noticeably longer.

Up to 60% less drivetrain friction vs stock Rival/Force. The factory bushings are the cheapest part of an otherwise capable groupset — typically costing 2–4 watts at race power. OSPW closes that gap so your Rival or Force build performs like a Red AXS bike where it matters: under load.

Carbon-fibre cage tuned for AXS shift dynamics. Generic cages disrupt SRAM's electronic shift timing. The ALPHA cage is tuned for E1 derailleur geometry so shifts stay crisp and consistent across the cassette.

Custom seal, 60% better moisture protection. Wet rides and pressure washing destroy standard derailleur pulleys within a season. The redesigned seal blocks water and grit so the bearings keep spinning quiet through any weather and trail you ride.

Plug-and-play install in under 15 minutes. No chain length change, no AXS recalibration — bolts onto your existing Force or Rival E1 derailleur with the supplied tools.

2-year warranty, 60,000 km service interval.
