Well, I've installed a new axle on the Trek, a new chain, and new tires. I also bought some new bar tape, but didn't have the time to put it on. The old Trek worked pretty well this morning on the club ride. It did much better than its hot, sweaty owner.
I bought a couple of Continental Ultra Sport tires from my LBS last night for $18 each. I'd like to buy tires with better puncture protection, like the Continental Ultra Gatorskin for this bike, but I didn't want to shell out the $40 per tire. These tires rode well for me today. They're 28's so I can ride some short stretches of gravel also.
Jon suggested that I re-align the dropouts, but two of the mechanics from my LBS have never heard of such a thing. I think I can make my own tool out of a couple sections of threaded rod - stay tuned for further updates.
The heat is supposed to break tomorrow and I will happily welcome it. All you people out there in bike land stay cool.
