the Tension 1

Matt Black / Light Blue

Utilising a versatile geometry means any task from commuting to CX racing are all well within the scope of this adaptable machine.

"Designed for hour-long racing efforts, or hacking through the woods at maximum speed."

Introducing the Tension 1

A first step towards the podium. Our 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.
