CeramicSpeed OSPW X ALPHA for SRAM XPLR E1

The CeramicSpeed OSPW X ALPHA is a purpose-built oversized pulley wheel system for SRAM AXS XPLR E1 derailleurs. Engineered for gravel and mixed-surface abuse, it combines CeramicSpeed’s low-friction bearings with off-road sealing and a reinforced cage to deliver smoother shifting, reduced drivetrain drag, and long service intervals—exactly what XPLR riders demand.

Oversized pulley architecture reduces chain articulation to lower drivetrain friction and improve efficiency under load

ALPHA off-road sealing package enhances contamination resistance for dusty, muddy, and wet conditions

Reinforced cage and CNC-machined pulley wheels maintain precise chain control over rough terrain

Long-life grease specification and serviceable bearing system extend performance between maintenance intervals

What’s Included

OSPW X ALPHA cage assembly pre-fitted with CeramicSpeed bearings and oversized pulleys

Small parts/hardware as required for SRAM AXS XPLR E1 fitment

Lubricant/grease syringe for ongoing bearing service

Setup and service instructions

Key Features

Off-road sealing – ALPHA disc-style protection and labyrinth sealing to keep out dust, sand, water, and grit

Efficiency you can feel – oversized pulleys and premium ceramic bearings reduce drag while maintaining crisp shifts

Shift stability – optimized tooth profile and cage stiffness improve chain wrap and retention on rough surfaces

Serviceable longevity – bearing system is user-serviceable; long-life grease spec suits gravel and adverse weather

Built for gravel – designed around the chainlines, cassette ranges, and chain types used by SRAM XPLR systems

Compatibility

Derailleur – SRAM AXS XPLR E1 (Force XPLR E1 / Rival XPLR E1)

Drivetrain – 12-speed SRAM AXS XPLR 1x gravel systems using Flattop chain

Cassette range – optimized for XPLR cassettes up to 10–44T

Not compatible with SRAM Eagle/T-Type MTB derailleurs or non-XPLR road derailleurs

Core Specs

Pulley sizes – oversized upper and lower (typical OSPW geometry for reduced chain articulation)

Cage material – reinforced alloy/composite construction for stiffness and impact resistance

Pulley material – CNC-machined aluminum with CeramicSpeed ceramic bearings

Finish – black, low-gloss, with subtle branding

Maintenance – periodic re-grease per instructions; quick visual inspection after wet or dusty rides

Installation Notes

Direct replacement for the stock pulley cage on SRAM AXS XPLR E1 rear derailleurs

Follow torque settings and B-tension guidance provided; confirm freewheel clearance at largest cog

Recheck limit screws and indexing after installation; test shifting across full cassette under load

Ideal For

Gravel and adventure riders seeking lower drivetrain friction with reliable sealing for harsh conditions

Racers who want consistent shifting and efficiency across long, dusty, or wet events

Riders prioritizing serviceable, long-life performance from premium drivetrain components
