Tuning parts

It is hard to make the SPEEDHUB better — but it can be adapted to special bikes and needs. The parts below are made by other companies, and Rohloff has checked that they work well and safely with the SPEEDHUB. The maker is responsible for each product and its description.

Other, non-approved parts can partly void the warranty and lead to a repair being refused — see Accessories: frequently asked questions. If one of them interests you, ask us and we will tell you whether it suits your bike — get in touch.
