Of course there are easier ways to skin that particular cat, though they might not be OTS with a #35 sprocket.

I am having trouble seeing the benefit of shift-on-the-fly in this case, but ease of adjustment is killer. Every year we find that we are pulling 21 amps somewhere -- click it down 25% and no more breaker pops, without rebuilding a complicated drive train.

Keep in mind that bicycle chain is not #35 chain. It will also be necessary to modify the output somehow to accept a different sprocket or to otherwise drive something.

It might be interesting to use these in a one-way bearing application, as most one-way bearings of FIRST-robot size -- at least those that I've seen -- are not rated for the high-torque applications present in our mechanisms.
