The Schlumpf High Speed Drive is one of our favorite pieces of bicycle engineering. This drive is compatible with any rear gearing system and features a whopping 250% gear range.
There must be a terrible amount of friction on the planetary gears in this Schlumpf system (it's Swiss, not German). I certainly wouldn't use it on any bicycle that I wanted to go fast on.

Wow...All of a sudden there is a use for those old Mavic BB Champfering tools...provided it's at the same angle.
