"It's a single speed geared a bit higher than I might have preferred: 48X16, which is 81 gear inches. It makes my knees hurt, but he's young and strong and shouldn't have a trouble.

It comes in on Thursday. Who knows, maybe I'll call out the orthopod and tell him as a handicap I'll ride the singlespeed and still kick his ass. "


Just ride at 90 rpm at the front of the group (21+ mph) no matter how much it hurts. After the ride seek out "Mr. Othropod" and remark that you just took your first single speed ride and ask "were you riding today?, I didn't see you". That's what I would do.
