A first step towards the podium. Bombtrack accessible Tension 1 model uses a hydroformed aluminium frame and carbon fork to provide a full-on racing experience. A Sram Apex wide-ratio 1x11 groupset ensures it’ll keep up with the competition, while hydraulic brakes keep you in control. With a threaded T47 bottom bracket and our new single-ring Lyre crankset, it’ll survive multiple season’s worth of mud without complaint.


  • Full carbon fork with through axles and flat mount disc brake. 
  • Lightweight aluminum frame with heavily hydro formed tube profiles and T47 bottom bracket. 
  • New Bombtrack Lyer 30 mm alloy crank with 40t direct mount chainring.

  • Tubeless ready WTB ST i19 rims with new tubeless ready Challenge Grifo TLR 700 x 33C tanwall tires.
