Assume the noisey brake was why your max speed was less than mine today! Recall I gave you the name/phone number of my very local bike mechanic.
Average speed? Yes 0.02 min/km slower than you. Can you actually see my max speed? It was 33.8kmh, way slower than your 55.9!! Have you considered sprinting as a career choice?
Do you mean 0:02min/km slower?
