KMC sprocket 11/128" for Bosch Active and Performance Line

Not for Active Line Gen3 from model year 2018 and Active Line Plus.

Available with 15, 18, 19, 20 and 21 teeth.

A larger sprocket can reduce the cadence at higher speeds. It can therefore be quite useful to install with the tuning also a larger chainring.

Note that for the installation of an ISIS crank puller and a locking ring tool are required. Both you can purchase from us.
