This is probably sort of boring for you to read about, but I put about $300 into my bike in the last couple weeks. This includes:
-Overhaul of front and rear hubs
-New shifter cable
-New chain and rear cassette
-New bar tape
-New 36-tooth front sprocket
The end result is a much better-functioning bicycle. The mechanic did the first four items for me, and the did the last three myself. I only realized I needed a new sprocket once I rode with the new chain and found it didn't fit well with the wear on the smaller front sprocket. So I got a new one and put it on this evening.
When I put the kevlar tires in late 2008/early 2009, I said that I'd report back on their performance. Well, they did perform well, as I only got two flats in a year and a half; one was on the way to Pittsburgh, due to a hard pinch on a tree root. The other flat was a few months ago. However, the tread on the tires didn't last quite as long as I would have hoped...I had to replace them because in addition to being cut up from glass, they had also developed some bald spots where the tread had come off to reveal the kevlar layer underneath:
Aron organized a bike trip this weekend with a larger group (7), doing part of the ride we did on the C&O Canal and Great Allegheny Passage last fall. Just three days, about 30 miles per day, but I'm definitely looking forward to it.
