Hey guys, newbie here, recently bought a 2012 Gt aggressor 1.0 size large, Im beginning to think the large may be a little too big and have started messing around with the idea of a FS. My question is will all the parts from my GT fit onto this frame, bb and all? The frame I've been looking at is based on the right price as well. Any input is greatly appreciated.

I can't post links yet but it is the Jamis Parker II Frame '09 > Components > Frames > Mountain Bike frames | Jenson USA Online Bike Shop

Thanks again
