I have a 2003 Trek 1000, only about 3000 miles on it. I took several years off from riding it but have put close to 2000 of the miles on it since June. I've started to notice a lot of the cheaper components and have been bit by the new bike bug. However i really do like my bike and wouldn't be opposed to just upgrading it. My question(s) is what order should I upgrade in if I did and what would be a realistic price tag of the upgrades, stipulating that most of the work would be done by my LBS.
Current setup on the bike is stock minus seat and pedals (SORA components and 32 spoke Alex Rims(not sure of model))
Better built wheels, clyde & rough road worthy, with hubs compatible for later upgrade to 9 or 10 speed.
better shifters, can be shifted from the drops unlike SORA
Shimano 105 or better rear deraileur
9 or 10 speed cassette
Shimano 105 or better front deraileur
