Cross Country With speed and pedaling efficiency in mind, cross country (XC) bikes are the lightest mountain bikes with the least suspension travel (typically 0 - 120mm). Trail Trail 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. Enduro If 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. Gravel Think of gravel bikes as the SUVs of the road bike world. Designed to excel on rougher roads, gravel bikes combine drop bar efficiency with mountain bike comfort, making them ideal for a variety of two wheeled adventures.
