About Rohloff
Rohloff AG from Fuldatal near Kassel, Germany, builds the SPEEDHUB 500/14: a 14-speed gear hub with evenly spaced gears, a 526% gear range and a sealed oil bath. As robust as the hub is, Rohloff sells small wear and replacement parts individually, so a SPEEDHUB is repaired, not replaced.
BoodaBike (Massive Bikes, Budapest) is an official Rohloff service centre, trained by Rohloff, and an official European distributor of Rohloff hubs and parts. We sell genuine Rohloff parts and we are happy to help you identify the right one for your hub version.
