Update your rear derailleur with CeramicSpeed shifters for reduced friction and extended life.

Rollers are the fastest spinning bearings on your bike, so renewing them with a CeramicSpeed set is an effective way to save you energy.

CeramicSpeed aluminum shifters are specially designed to reduce friction to an absolute minimum, virtually eliminating the resistance associated with standard shifters.

The special design guides the chain in its ideal line and makes a very smooth gearshift.
