TENSION 2
As you move up the rankings in the Tension collection, the Tension 2 comes with a Sram Rival groupset, Hunt 4 Season wheels and a Ritchey cockpit. A more race-winning gear ratio suits the price point while possessing the same aggressive geometry found throughout the collection. The wheelset hosts long-lasting cartridge bearings with reliable Challenge Grifo tyres, whatever the conditions, and if you so wish, make switching to tubeless simple. A T47 threaded bottom bracket provides peace of mind against mechanicals, along with the bike’s durable chassis.
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.

¹ 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.
