Schlumpf Speed Drive (SD Splined, 60-72mm, Aluminum)
The Schlumpf Speed Drive is ideal for town bikes: single speeds, fixed gears, internal gear hub bikes, or bikes with only a single, rear, derailleur. The close 1.65 overdrive ratio means shifts can be made more often and more comfortably. This is also the best Schlumpf model to combine with a Rohloff SPEEDHUB 500/14 for those applications in which the gear range of the SPEEDHUB 500/14 is not enough. It's also great for small-wheeled bikes to get a larger gear ratio without a huge physical chainring.
