It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus, or just getting from A to B on any surface - Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter - Smaller frame sizes (XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently - Marlin models in XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount - Like every model in the Marlin family, it's backed by Trek's lifetime warranty
