Jump head-first into the off-road world aboard Trek's Mamba. This cool dirt-worthy bike starts with a lightweight Gold aluminum frame with Gary Fisher's proven G2 geometry. Complementing the sublime ride is a RockShox fork that gives you 100mm of travel to add even more cush and steeering confidence to the big 29-inch wheels. Proven parts hang off the sweet frame and fork with Bontrager disc wheels with Hayes disc brakes. And, you also get the solid performance of Shimano shifting and the quality of Bontrager controls. It all adds up for a ride that truly has to be ridden and ridden hard!
