Hi all, I put together lots of good info on the new Rotor Cranks RS4, and some suggested chainring sized for bent riders.
Feel free to contact me with questions.

Interesting idea, but problem I can see with that is on one part of the revolution of the cranks one foot is more forward so that will work well, but what about the other way when one foot is farther back on the revolution. Wouldn't this make it harder?

the cams prevent this, it is very efficient on a recumbent and increases speed substantially as well as making climbing easier

I must agree with Gary on this one...... A friend of mine......Frank Geyer races with them and of course also trains with them. He races a challenge jester and gained even more speed with these cranks plus lowering his heartrate at the same time. I plan on getting a set........ just don't know yet which set to plunk the money down for yet. Still waiting on my new carbon frameset yet.
The rotor cranks appear to be way worth the money. Huge gains for recumbent riders.

Out of curiousity are they more efficient on a bent? and why if so.

Rotor Crank
Chris and Gary, I like speed, though I don't have the opportunity to race others hereabouts. I tend to mash the big ring so I'm intrigued by the stroke-efficient concept of Rotor Cranks, but I'm also concerned with the extra weight of those things. If Chris (and Frank and Garrie, et. al.) go to the extent of weight-saving carbon frames (and, I'd assume, light-weight wheels and everything else) then why heavier cranks? Do they really more than compensate for the extra rotational weight?

I was concerned with the extra weight also, but according to everyone that uses them..... it doesn't seem to be a penalty. The extra efficiency overcomes the weight penalty. I will still have a sub 19 lb bike anyhow. They all claim hill climbing is much easier now on the recumbent.
