There was always some question about the longevity of the bonded aluminum Treks from the early 90s, but I have 2 of them now with no problems with either. My 8000 is near mint as I'm the original owner, the 7000 I bought on eBay for $125 when my son took the 8000 to school, but now I have it back. The 7000 is a little beat up, but that's what makes it a great bike for NYC.
