I have the opportunity to purchase a 2005 Specialized Stumpjumper Pro XL frame with new Fox RP3 rear shock for $400. The frame is my size and is in very good condition (although it's listed as an M5 frame and my research shows the 2005 to be an M4 frame). I would take the upgraded parts from my 2003 Jamis Dakar Sport (FSA cranks, Hayes ElCamino hydraulic disc brakes front and rear, XTR M950 Front and Rear Derailleurs with SRAM attack shifters. SRAM 9speed cassette. SID race rear shock, Manitou Black front fork, non lockout) and move them to the Stumpjumer frame. Two questions - 1) Does $400 seem like a fair price for the frame or should I offer less and 2) what do you think I could get for the Jamis frame and SID race rear shock. Any thoughts, opinions, etc. would be greatly appreciated!
