Thanks for your help guys.
After considering my options I have decided to buy a new frame. I tried asking my LBS but he was far more interested in selling me a new bike!
Any suggestions for a hard tail frame?
I ride XC but go to trail centers now and again
The Marin Hawk Hill 2009 components will need to be transfered acorss onto the new frame:
Brakes:Avid Juicy 3 Hydraulic Disc with 6" Rotor
Cassette (Rear cogs):SRAM PG-950, Power Glide II, 11-34, 9 Speed
Crank:FSA Dynadrive, 44/32/22
Derailleur (front and back): SRAM X-5
Seat Post: Alloy Micro Adjust, 30.9mm x 400mm
Headset: TH-888, 1 1/8", Threadless
