I'm curious as to how much of a difference shorter cranks would help with cadence on a road bike. I'm trying to focus more on cadence these days rather than mashing. I would think that a shorter crank would be faster to complete a revolution... I currently use 175mm cranks because that's usually what comes with a 61cm bike... I'm thinking of going to a little shorter crank so I can get my cadence up a little. I'm just curious if anyone here has tried that and if shorter cranks caused any discomfort or anything else that I didn't think of. It doesn't seem like. 2.5mm or 5mm would make a huge difference, but I know if my seat drops a few mm, it definitely makes a difference.
