CeramicSpeed OSPW RS 5-Spoke Pulley Wheel for SRAM Force E1/Rival E1

The CeramicSpeed OSPW RS 5-Spoke is an oversized pulley system developed for riders who want a more refined drivetrain upgrade than replacing individual pulley wheels alone. CeramicSpeed redesigned the RS generation with a distinctly modern, angular appearance intended to integrate naturally with contemporary performance bikes and groupsets. The complete cage-and-pulley concept is aimed at riders building around drivetrain efficiency, precise setup and a clean, cohesive rear-derailleur aesthetic.

Stronger RS Platform. The updated cage has been reinforced to improve strength and durability compared with the previous OSPW design. That structural focus is useful for riders putting the system through regular training, racing and mixed riding conditions, where the derailleur assembly experiences repeated shifting loads and vibration. The open 5-spoke pulley format retains CeramicSpeed's recognisable oversized-pulley character while giving the newer RS generation a sharper, more contemporary appearance.

More than Pulleys. The OSPW RS is designed as a complete system rather than a pair of replacement wheels fitted to the original derailleur cage. This allows CeramicSpeed to control the relationship between the cage, pulley architecture and bearing system as one assembly. For riders already investing in a high-level drivetrain, that makes the OSPW RS particularly relevant as a focused upgrade where efficiency, durability, setup refinement and visual integration all matter, rather than as a purely decorative component.
