• Used For: Enduro More

  Used For

  
  
  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.
  
  
  
• Suspension: Full Suspension More

  Suspension

  
  
  Full SuspensionEngineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.
  
  
  
• Gearing: 1 x 12
• Frame Material: Carbon More

  Frame Material

  
  
  CarbonCarbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.

  Brake Levers

  
  SRAM Maven BronzeSRAM Maven Bronze features monstrous 18 and 19.5mm pistons driving 50% more power than Code. But best-in-class power means nothing unless you’re able to harness it.
