CeramicSpeed OSPW Aero Pulley Wheel System
About
Description
CeramicSpeed OSPW Aero oversized pulley wheel system for Shimano Dura-Ace 9100 and Ultegra R8000, developed with aerodynamics firm Drag2Zero. The aero carbon-reinforced cover shields the pulleys from the wind. CeramicSpeed claims it cuts drag at the derailleur by about 40% compared with stock, and the oversized pulleys on ceramic bearings reduce drivetrain friction.
