- Material: Stainless Steel
- Used For: Cross Country, Trail, Enduro, Downhill Cross CountryWith speed and pedaling efficiency in mind, cross country (XC) bikes are the lightest mountain bikes with the least suspension travel (typically 0 – 120mm). TrailTrail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike. EnduroIf you’re looking for maximum performance while flying down heavier trails, an enduro bike is for you. These bikes combine ample suspension travel (typically 150mm+) with descent-focused frame geometry and components that allow for reasonably efficient pedaling. DownhillFor bike park days and shuttle laps, there’s nothing like a downhill (DH) bike. Designed to tackle the roughest trails at high speeds, these bikes have long suspension travel (typically 170mm+), huge brakes, and unreal descending capabilities. DH bikes are not as suitable for tight trails or climbing.
