OSPW X ALPHA for SRAM XPLR E1

Specifically engineered for the 13-speed SRAM Red XPLR E1 (and compatible with Force/Rival XPLR E1), the OSPW X ALPHA is built to handle the unique demands of gravel racing. It features a reinforced, injection-molded carbon fiber cage that is both lighter and stiffer than previous generations to ensure precise shifting even when covered in mud. The system uses massive 14-tooth upper and 20-tooth lower ALPHA Disc pulleys. These solid discs eliminate the risk of grass or twigs getting caught in traditional spokes while the Active Debris Remover (ADR) technology—featuring a bladed dust cover—actively pushes contaminants out of the bearings as they spin.

Key Features

• 13-Speed Optimized: Designed specifically to accommodate the wide-range 10-46T cassettes used in the latest SRAM XPLR E1 groupsets.

• ALPHA Disc Pulleys: Solid aluminum disc design prevents debris ingress and provides superior structural stiffness for the snappiest possible gear changes.

• Active Debris Remover (ADR): A patent-pending system that combines a stainless steel dust cover with a bladed groove structure to keep bearings spinning freely in dusty or muddy conditions.

• Composite Tooth Profile: The pulley teeth are made from a high-performance composite that reduces chain noise and offers significantly better wear protection than standard alloy.

• Handbuilt Ceramic Bearings: Standard with coated races (in most premium variants) that are 75% harder than steel, backed by a lifetime warranty.
