CeramicSpeed OSPW Pulley Wheel for SRAM Rival AXS

The CeramicSpeed OSPW Pulley Wheel System for SRAM Rival AXS is engineered to deliver smoother shifting, reduced drivetrain friction and enhanced performance. Designed specifically for Rival AXS derailleurs, it transforms drivetrain efficiency by optimizing pulley size and minimizing mechanical resistance for every ride.

Oversized Wheels for Maximum Power Transfer: Featuring a 15-tooth upper pulley and a 19-tooth lower pulley, this system dramatically reduces drivetrain friction by 35–40% compared to standard pulley wheels. The increased diameter allows the chain to articulate less, improving power transfer and extending component life.

Customizable Spring Tension for Perfect Setup: With two adjustable spring tension settings, riders can fine-tune the system based on terrain, riding style, or racing demands. This customization ensures crisp shifting performance whether you're sprinting, climbing, or cruising long endurance miles.

Carbon Fiber Cage Built for Durability: The OSPW system uses a lightweight custom-molded carbon fiber cage that enhances stiffness while keeping weight low. This robust design ensures long-term durability, even under the high torque and rapid shifting demands of modern electronic drivetrains.

Ideal for maximizing the capabilities of your SRAM Rival AXS groupset, this OSPW system delivers smoother mechanics, improved efficiency and long-lasting performance—all while keeping your drivetrain running at peak smoothness.
