Precisionbuilt for riders across the UK who demand marginal gains without compromise, the CeramicSpeed OSPW RS 5 Spoke delivers elitelevel drivetrain performance with aerodynamic efficiency, longterm durability, and ultralow friction. Designed specifically for Shimano DuraAce R9250 and Ultegra R8150 12speed Di2 derailleurs, this oversized pulley system offers a tangible upgrade for every ride — from time trial to training block.
At the heart of the system is a 5spoke carbonreinforced cage, carefully sculpted for weight reduction and enhanced aerodynamics. Paired with 15T and 19T pulley wheels and CeramicSpeed’s signature lowdrag bearings, the RS 5 Spoke minimises energy loss throughout the drivetrain — saving up to 2.4 watts compared to stock pulley setups. The result: sharper shifting, smoother pedalling, and more power to the road.
Every detail of the RS 5 Spoke is built to endure. Manufactured in Denmark, available for UK riders, it boasts a matte black finish that complements highend road builds and a 4year warranty (upgradeable to lifetime), reflecting its racetested reliability.
