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, providing energy savings starting from 2.4 watts over standard Shimano systems. This is an updated version of the Oversized Pulley Wheel System for Shimano 9200. This new design has an integrated stop tower for easier mounting.
The oversized pulley wheels have 3-5 times the lifespan of commonly used standard pulleys on the market. Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur, the upper and lower oversized aluminium pulley wheels come fitted with CeramicSpeed Bearings with standard or coated races.
Please note while there are visual similarities in the 9100 Series OSPW and 9200 Series OSPW, the spring tension settings, rotation stop tower placement, and mounting pin depth are slightly repositioned and as such the systems are not cross compatible.
