It's drizzling and I don't feel very good today, so I bribed my son to help me replace the chain on my bike...
Took off a SRAM PC 1031 chain and put on a KMC X10SL chain (which was not cheap!) I'm sure this will magically improve my shifting, which has been OK but not great lately. Perhaps that's due to chain stretch, the chain I took off was between .5 and .75% stretched. People say that the KMC chains are terrific, can't wait to find out.
I also retensioned both wheels - maybe 5 spokes total needed a minor tweak to get everything back in the same vicinity. I'm really impressed with how sturdy my wheels have been. Easton EA90 SL. The front rim is still damaged from hitting something 6 months ago, so I'm wheel shopping (going to build up a set of wheels during christmas break)
Also took the wheels off and cleaned the entire frame. The rear DR had all kinds of muck on the little follower wheels. Yuck. Got that all cleaned out too.
Greased the pedals (speedplay recommends it quarterly or so), thought about changing the brake pads but there's still some life left in those. Adjusted the front DR.
All in all a good day's work, and now I don't want to ride my clean bike in the drizzle. Sigh.
