Upgrade your Shimano 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.
Pulley made of titanium with ceramic bearings for reduced friction and extended lifetime. Compatible with all Shimano 11-speed derailleurs.
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.
