Bosch Chainrings & Cranks

Chainrings, sprockets, spiders and lockrings that fit the Bosch drive unit – genuine Bosch plus Bosch-fit parts from SRAM, KMC, Stronglight, FSA, Hope and PILO – and Bosch-fit crank arms. What fits depends on the drive unit generation (Gen 2, Gen 3 or Gen 4) and the chainline, so check both before you order.

Removing a Bosch lockring needs the right tool – see eBike tools.
