Perfect working condition Trek Rumblefish II 29er 21.5" frame size. Has been converted to a 2x10 drive train set-up with an E-Thirteen Turbo Charger bash guard (original chain ring is available with bike if needed). Drive train consists of Shimano XT cranks, shifters, and front derailleur, XTR rear derailleur and avid Elixir R brakes. Original Bontrager 29-3 tires are included with the bike. I also have a set of rubber queen 2.4 tires that can be negotiated.
