If youre the one in your group thats always getting followed on the trail the Rockhopper Expert 29 is here to make sure that it stays that way. We built it to be light durable & exceedingly capable but how we did it is far more interesting. It all starts with an alloy construction thatll resist corrosion & take a beating while the components are purposefully selected to squeeze every last drop of performance for the money. But what were most proud of is the Rockhoppers Trail 29 Geometry. It features a low bottom bracket roomy top tube & short chainstays to keep you ripping & confident both up & down the trail. The frame is constructed from lightweight A1 SL aluminum in order to provide a compliant durable platform to support our acclaimed Trail 29 Geometry. Combined you get a bike thats more than efficient on climbs & eager to get down to business on descents.A Manitou M30 29 fork offers 80/100mm &40;size-specific&41; of plush trail taming travel & stiff 30mm stanchions. Its hard to beat the blend of durability reliability & performance that the Shimano SLX rear derailleur provides. Its designed to take a hit & more importantly its shifting is crisp precise & always on the money.
