Yeah, if you took rim temperature readings when Ex was lapping the field in the TX state champ crit this year, I'd bet Ex's would be the hottest on the course. I'm not great at cornering, but I imagine if I was, that there'd be no way to corner that fast w/out aggressive braking. Better brakes would = faster unless climbing... but on the descent they would make some of that back up.

I worry a bit about the cuts in pileups, but the rotor is in a pretty protected region, and could probably dulled in manufacturing anyway w/out adding too much weight.
