Smoked a pair of younger guys on a 5 mile, mild descent today. It ended up me and a former cat 2 to reach the regroup point first by nearly a minute. It was awesome.

I learned later that one of them was riding the other guy's mother's bike, and the right (2005 9 spd Ultegra) shifter required the use of both hands, and the brakes were shot. His friend slowed to ride with him :/
