Additional Features
DUB Technology– The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
- Material: Aluminum, Carbon Fiber
- Used For: Cross Country, Trail, Enduro 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.
