The latter. For some though, mashing the 53 at a cadence under 100 might be easier than spinning all the time at 100+. Excluding the short sprinting type efforts, one of my knees will start hurting/swelling if I try to spin above 95 for extended periods of time. It's related to old sports injuries, not bike fit.
