Crank arm experience for the long-legged?
So, while I'm "only" 6 feet tall, my cycling inseam is 36" (or 914.4mm for those who think in metric). I'm told that this is kinda on the high side of average... At this point, I've spent most of my miles on 170mm cranks and some 175 now. Obviously it works, but, given that my leg length puts me into the upper end of frame sizes, I'm kinda wondering about trying something longer. 180mm or maybe more? Before dropping the money on this, I was curious about the experience of others with long legs, have you tried going longer on the cranks and if so what did you find?
