Hey Dan....steer clear of the Atomik AX ( AGB-27 ) The frame is a poor design and cracks easy, especially were the rear shock bolts on. The rear shock set up is bodgey as well....Instead look at the Atomik Moto X
( Agb-21 ) my Brother has one of these and he's never had any trouble with it. Mind you he dosen't jump the thing.
Good Luck
