We install the Schlumpf High Speed Drives in house, and can install it for you before or after the purchase of a trike. Either way, installation is free. The simplest way to get the Schlumpf on your ride is to send us your boom or bring in your trike.
Increase your gear range and simplify your drivetrain. Get a Schlumpf.
Elegant and durable enough to last a lifetime, Schlumpf gearing systems are high-precision devices manufactured with passionate enthusiasm. Since 1992, mountain-drives have been used by thousands of people around the world to extend the gearing range of both derailleur- and hub-gearing systems.
Mountain-Drive:
- Shifts down by a factor of 2.5
- For example: Combining Mountain-Drive and a 7-speed Nexus hub (with a 44t chainring, 18t rear cog, and 700C rear wheel) results in a gear range from 17 to 104 gear-inches, or 1.3 to 8.3 meter of development (611%) with no overlapping gears!
