I have to ask: are you sure you "need" 180 mm cranks. Lots of people read formulas for crank length and think they need proportional cranks. The "logic" of "crank length should be proportional to leg measurements" has been around for a LONG time, and lots of people have turned that "logic" into a formula for determining crank length. Only one problem: the research doesn't support it. One key feature that is often ignored in these discussions is the duration of muscle contraction that is controlled by cadence. It just may be that there is an optimum here, which is why there is a fairly narrow range of cadence for optimum performance. Longer cranks tend to mean lower cadence, moving you out of that optimum range. Crank length has been a point of debate since the introduction of the "safety" bicycle in the late 1800s, and there have been all sorts of fads in that regard.JM714 said:I need a Campagnolo Record 10s UT crankset in 180. Prefer new, but would settle for a used one in good shape. I can't seem to find one out there.
