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.
