Thanks a2psyklnut, I've done about 2,500 miles on it. However, this was through the winter, so plenty of rain and salt was around to attack it!
It's still going fine, I'm planning on taking it to the LBS when I'm next on holiday (as I use this bike to commute on) so that I don't have to resort to using a car to get to work (hey, I've got the bike commute bug
).
Either that or buy a spare rear wheel so that I can leave my current one at the LBS for them to sort it out.
