That is a definite concern of mine. I have a compact double that I bought and need to get rid of because it wouldn't clear the chainstays. I am assuming that a touring triple crank would be designed to accommodate frames with wider chainstays. If 3mm of overall spindle length determines whether or not the crank is usable with my frame then it was probably iffy to begin with. I just hate not being able to head to a bike shop and buy something, try it, and return it if it doesn't work. Living in Korea is for the birds.
