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 that’s more than efficient on climbs and eager to get down to business on descents. A Manitou M30 29 fork offers 80/100mm (size-specific) of plush, trail taming travel and stiff 30mm stanchions. It’s hard to beat the blend of durability, reliability, and performance that the Shimano SLX rear derailleur provides. It’s designed to take a hit, and more importantly, its shifting is crisp, precise, and always on the money.
