Construction: exploded view
Full transparency, no secrets: Rohloff wants every cyclist to be able to see how the SPEEDHUB is built, down to the smallest detail. The exploded view shows the hub broken down into its parts — the numbers refer to the list below.
The 14 gears come from three planetary sets; how, is shown in Planetary gearing. For the parts that fit the hub to a bike (axle, torque support, shift actuation), see Modular system.

Frequently asked questions
- How many parts does a SPEEDHUB have?
- The exploded view counts more than sixty positions — gears, shift elements, bearings, springs and seals — well over a hundred pieces in all. It all runs in a sealed oil-bath shell, so you never need to take the gearbox apart.
