the Tension 2

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

"The beauty of the stiff alloy frame is also that it climbs quickly, readily flying when you open up a sprint. The bike handled tight & twisting turns, loose downhill & pedaly sections, and repeated short sprints all without hesitation.“

Introducing the Tension 2

Another step up the rankings. With a Sram Rival 1 groupset, Hunt 4 Season wheels, and a Ritchey cockpit, the Tension 2 looks the part propped in any pit lane. With the same purposeful geometry found across the range, race-tailored gearing means it’s suited to all-out efforts. Making tubeless set-up easy, its lightweight wheels employ long-lasting cartridge bearings, while Challenge Grifo tyres provide excellent speed and traction across mixed conditions. Ready to compete all season long, its durable chassis also features a T47 threaded bottom bracket for zero-fuss maintenance.

    * Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
