I've been looking to get a 29er single speed frame (I've got an 03 Cannondale Jekyll and Bianchi SISS) and I really like Specialized's format to be able to run gears or ss because I may want to go 1X9 in the future. Is there anyone that sells a new 08-09 Stumpjumper 29er frame or if not where are some good places to find a used one (I'd be a large frame)? The new rockhoppers also have the adjustable sliders but you have to buy the whole bike and those bikes aren't really built up to how I like them (with the dart fork and 8 speed) and I think it'd be cheeper to build up cause I can steel some parts off the Bianchi and it would also be funner for me to build up a frame. So what should I do? Just buy a new Rockhopper Comp and upgrade or find a used/new frame? Any help or input would be great. Thanks
