CeramicSpeed OSPW X ALPHA SRAM XPLR E1 Rear Derailleur Pulley System – Maximum Efficiency for Gravel Riding

CeramicSpeed OSPW X ALPHA – an oversized rear derailleur pulley system designed for 13-speed SRAM AXS XPLR E1 drivetrains. Large 14- and 20-tooth ALPHA Disc pulleys, hand-built hybrid ceramic bearings and a reinforced carbon fibre cage help reduce friction, ensure smooth chain operation and maintain reliability in demanding gravel riding conditions.

Key features:

• Compatible with SRAM XPLR E1: suitable for 13-speed SRAM RED, Force and Rival AXS XPLR E1 rear derailleurs.
• Oversized ALPHA Disc pulleys: the system features a 14-tooth upper pulley and a 20-tooth lower pulley.
• Reduced drivetrain friction: larger pulleys reduce chain articulation and help transfer the rider’s power more efficiently.
• Hybrid ceramic bearings: hand-built CeramicSpeed bearings provide smooth rotation, high efficiency and long service life.
• ADR bearing protection: the patented system with stainless steel shields helps protect the bearings from dust, dirt and moisture.
• Active debris removal: grooves formed around the bearing shield direct contaminants away from the bearing as the pulley rotates.
• Durable tooth material: composite teeth offer high wear resistance and help reduce drivetrain noise.
• Solid aluminium discs: the closed pulley construction increases stiffness and helps prevent sticks, stones or other objects from becoming trapped between spokes.
• Reinforced carbon cage: moulded carbon fibre construction combines strength, durability and low weight.
• Designed for gravel riding: the construction is engineered for reliable performance on dusty, muddy and technically demanding routes.
