124Spider

Hi,

We are enjoying our tandem immensely (we've had it for a couple of years, having ridden it several thousand miles).

But we still have one intractable problem: My wife can't generate power at the high cadence I need in order to generate power. I'm a lot taller than my wife, with legs at least 15% longer than hers. And yet, on our tandem, her cranks are 170, and mine are 175. I would think that her cranks should be 15% shorter than mine.

Has anyone here tried much shorter cranks for a much shorter stoker, and, if so, did it help?

Thanks!

Mark
