I stuck my R20 project in the road section - it's as close to a road bike as I own so far.
Its one of the more looney inventions of Sachs/SRAM - a dual drive. Basically a 3 speed internal hub with a 7 speed cassette body attached to give 3x7 gears.Rampage":3gza50eo said:What does the left hand gripshift do?

They also do a version that takes a freewheel.
I've sometimes thought about making a 72 speed mountain bike for no good reason at all.
