I know this is a trials forum, but, my cousin is selling a perfect condition GT Bump, the "real" version, from before Pacific bought out GT. He bought it for $300, and put about $100 into it. Here be the specs- GT Bump black/yellow frame, Kink BMX Chromo cranks, (no pedals) GT bars/Oury grips, Profile U brakes/green 'sticky' pads Alex rims-ground for braking, New dirt tire in the rear, The gears are 38/18 I believe, but he can throw in a 42(?)T front cog. Asking $200 or best offer.
Heres some pics: This frame is brand new, ridden maybe a month overall. Price has been dropped to $150 or b/o.
