To weight 200 lbs. I had the great experience, on sunday during my ride. My dur-ace cable broke off in the hood, while i was climbing a 8% grade/3000 ft climb. The rear der was set in the 12. The two otions were 1. turn around 2. continue climbing at 20-30 rpms. What do you think I did? Yeah, at some points, my computer was regestering a cadence 1 I was moving so slow.
