CeramicSpeed OSPW X ALPHA for SRAM XPLR E1 (Gravel)

The CeramicSpeed OSPW X ALPHA for SRAM XPLR E1 is a premium oversized pulley wheel system designed for SRAM Red, Force, and Rival AXS XPLR E1 13-speed derailleurs.

Featuring the new 14-tooth upper and 20-tooth lower ALPHA Disc Pulley Wheels, the system combines composite pulley teeth for reduced noise and extended wear life with solid aluminum discs that prevent debris from getting trapped during gravel riding.

Inside each ALPHA Disc pulley is CeramicSpeed’s patent-pending ADR (Active Debris Remover) technology, which uses a stainless-steel dust shield and a bladed groove pattern to actively deflect contaminants away from the bearing as it rotates—ensuring maximum bearing protection in harsh off-road environments.

The OSPW X ALPHA system also features a reinforced, injection-molded carbon cage, paired with hand-built hybrid ceramic bearings for unmatched drivetrain efficiency and long-term durability. Backed by a lifetime warranty.
