Went to downshift before pulling into my driveway yesterday afternoon, and *snap* went the rear derailleur cable. It was the original (1987) cable, so I guess it lived a full life.

Unfortunately the der "defaulted" to the 13-ring, which was going to be an issue. I want to commute, not do time trials. I got her up on the rack, manually pushed the derailleur in so the chain hooked up on the third-largest cog, then cranked in the high-gear screw to hold it there. It's my 16MPH ring, and I could shift to a larger front chainring if I need to go taller. Even with that, I was spinning too fast at 20MPH, so I was glad nobody tried to catch me, as I would have been an easy mark.

I still managed to pass two other riders. I was almost scared to do it.

Replacing the cable today before the ride home!

Happy Friday
