My Wife and I both have Giant OCR1 bikes. I'm 6' riding a large frame, my Wife 5'7" riding a small (men's) frame. Both cranksets are 175mm. We're both in our early 60's and I'm pretty comfortable with the length, but I think my Wife would be more comfortable with shorter crank arms. What are my options in comparable quality in terms of finding 165mm or do I wind up buying something more exotic (read "more expensive")?
I know there is varied opinion regarding crank length and much boils down to personal likes/dislikes, but it seems on the average that the shorter your are the somewhat shorter the crank arm should be.
Any suggestions would be greatly appreciated!
