New wheels!
These are the wheels I got from ebay. Mavic Open Sport rim on a Tiagra hub. The pic on ebay showed a black rim, but these are silver. Still, they look OK. They've replaced the stock wheels on my Carrera TdF. Between the two of them, and the different tyres, I've saved 700g, which isn't bad going, particularly if a decent chunk of what's left is at the hub rather than the rim. Besides, I'll need a set of wheels for my new bike next year...
I had real difficulty getting the cassette off the old wheels. In the end I went and asked my neighbour for help. I held the chain whip and he hit the lockring tool with a mallet a few times and it eventually came loose! Once that was done I managed the rest fine. I gave the cassette a good clean once I had it off, and took the chain off and cleaned that as well, and installed a split link to get it back on.
I've ridden the bike up and down the road, and it seems OK so far. If nothing else, shifting is a lot better, so maybe the clean did it some good! I'll take it out for a decent ride tomorrow night, assuming we don't get hit with an ice age between now and then.
Oh, and I managed to lose the magnet for my computer. Bum. I'll have to pick one up from Evans or something.
