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 aluminum with ceramic bearings for reduced friction and extended lifetime. The special design virtually eliminates the drag associated with standard pulley wheels and helps guiding the chain in its ideal line and perform super smooth shifting.
Compatible with all Shimano 9/10-speed Road/MTB derailleurs.
Every single bearing is hand built in Denmark under white room conditions. All parts are selected by hand for perfect fit, each bearing is spinned 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.
