These new solid jockey wheels from CeramicSpeed clean themselves

CeramicSpeed OSPW RS

CeramicSpeed has launched a new oversized pulley wheel (OSPW) RS derailleur pulley system today. The Danish brand says the OSPW has been ‘lifted into the future’ receiving innovative new tech features as well as a ‘distinctly modern and angular design’. It will be compatible with Shimano and Sram road groupsets. It does also share some tech features with the OSPW X for the Sram Transmission MTB unit that was launched last Autumn. 

The original OSPW (oversized pulley wheel system was launched back in 2015 and the brand unveiled its aero OSPW in June last year. OSPW systems have become a popular, if expensive way to improve drivetrain efficiency thanks to the larger derailleur pulley wheels themselves and ceramic bearings. 

CeramicSpeed says the updated design of the OSPW RS allows it to blend seamlessly into the contemporary design trends of modern bikes and groupsets. The brand claims there are also now more customisation options available such as multiple logo and colour options as well as two different types of lower pulley which we unpack in the tech info below.
