I have the same A1 Pro FS bike frame (15") but I have the disc spec - my bro bought it custom, and I bought it off him to help him with his wedding plans. He got much love out of it before he tweaked a vert in his back.
I currently have a set of Schwalbe CityJet tyres on mine as it is taking me round the Manchester - Blackpool charity ride for The Christie on 10 July.
What size is your frame - I could be interested in it as a spare and/or for my mate who has a Trek 3500 rigid?
Do you have a revised price?
For your interest, you can find both the 2001 RockHopper A1 FS Pro & the A1 FS Comp Disc spec on bikepedia ...
