Acceleration from 22mph to 36mph in 10 seconds? Really? Those physicists live in a world of their own. If I was able to push 500w I wouldn't be concerned much with the weight of my tires. Or maybe I would because it would mean that I'm a pro and for a pro even 1% matters...


I wish he did the same calculation for a sequence of accelerations from 0 to 15mph like one would experience in stop and go traffic while commuting.

I'm too lazy to do the math but I'm sure the proportion would be bigger than 6/500.

I once had some heavy ass tires and I'm not going back. I know what it feels like to me. I can definitely feel the difference and I enjoy my ride way more with lighter tires.
