the Tension C

A no-compromise race bike with a lightweight and unyielding carbon chassis.

"Head down, tongue down, pedal pedal pedal."

Introducing the Tension C

A World Cup-winning design. Mix it with the very best on our top-flight racer. Built around an aggressive carbon chassis, its weight is kept to an absolute minimum. Using a Sram Force One groupset with matching carbon crank, Hunt 4 Season wheels, and a Ritchey 4-Axis finishing kit, our carbon Tension is podium-ready. With narrow gearing and fast Challenge Grifo tyres, it’s designed to deliver you to the bell lap with enough energy left to boss the finishing sprint.

    * 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.
