Upgrade your SRAM rear derailleur with CeramicSpeed pulley wheels!
They ensure reduced friction and extended lifetime. Pulley wheels are the fastest spinning bearings on your bike, making an upgrade to CeramicSpeed an effective way to save you precious energy.
Pulleys made of aluminum with ceramic bearings for reduced friction and extended lifetime. Compatible with SRAM 11-spd XX1, X01, X1, Force CX1 and Rival 1 derailleurs with 1x11 setup. The special design helps guide the chain in its ideal line and perform super smooth shifting.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spun by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
