It features an integrated stop tower for simple installation and durability, and it significantly enhances gear shifting performance.The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world. This OSPW System has hand built CeramicSpeed Bearings installed in each pulley and comes with a 4-year warranty as standard and a lifetime warranty when choosing coated bearings. CeramicSpeed OSPW Systems are an industry-leading product, chosen by World Champions and top athletes around the world. 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 either standard or coated CeramicSpeed Bearings. For 8100 derailleurs, the cage uses the factory derailleur body washer. 9200 derailleurs will require the new included derailleur body washer. Since its introduction in 2015, the CeramicSpeed Oversized Pulley Wheel System has been through 13 unique derailleur compatibility developments. No other pulley system has the depth of use and trust as the CeramicSpeed OSPW, which counts both Men's and Women's Triathlon World Champions, World Tour professional road teams, XCO professional MTB Teams, and elite athletes worldwide as its users.
