So I began commuting to work this week (when the weather let me). One day I rode my '76 Schwinn Varsity with no problems. Last night I rode my '34 Colson. The ride in went smoothly, but the ride home was another story. As I was torquing hard up a hill I had the old skip tooth chain snap a link. This brought me to a standstill. Luckily a coworker saw me stop and was able to give me and the bike a ride home. I have another chain on the bench to replace the broken one and a few spare links somewhere to repair it.
