    As the fastest oversized pulley wheel system on the market, the CeramicSpeed Oversized Pulley Wheel System (OSPW System) has been developed to answer the increasing demand for improved drivetrain performance. The OSPW System optimises the overall efficiency of your drivetrain thanks to the extremely low friction of the CeramicSpeed Bearings and the unique design of the overall system.


    CeramicSpeed OSPW Systems will make you save watts and improve your performance in both indoor and outdoor training and racing. Upgrade your hometrainer with the watt-saving OSPW Systems and feel the difference immediately. Ride faster with CeramicSpeed in Zwift and other indoor training apps.


    The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world. The Oversized Pulley Wheel System for SRAM Red and Force AXS features a 15-tooth upper and 19-tooth lower pulley wheel setting for maximum efficiency. The handbuilt OSPW System has two spring tension settings that allow customised setup based on riding conditions.


    This OSPW System is also compatible with the 2020 11 speed SRAM Red eTap derailleur featuring a clutch.


    Please note: While there are visual similarities with the SRAM RED/Force AXS derailleurs, this OSPW system is not compatible with the SRAM Rival AXS, or SRAM RED, Force, or Rival XPLR eTap AXS rear derailleurs.

    *Giant & Liv Bicycles are available for purchase online, but due to warranty regulations, must be shipped to qualified Giant dealers, as bicycles must be assembled by a qualified bike mechanic in an approved store - This is an international policy and usually will require an additional fee to build the bike.
