TENSION C

Piloted by our very own cyclocross superstar, Gosse van der Meer, the Tension C is our full carbon fibre race bike. Gosse may be a one man team, but he has racked up quite a collection of silverware across the world with this beauty and it's easy to see why. A lightweight high modulus carbon frame and excellent Hunt 4-Season disc wheels fitted with Challenge Grifo tan wall tyres form a superb rolling chassis. Add in a Ritchey cockpit and SRAM’s race-ready Force 1x hydraulic groupset with close ratio cassette to keep the pedals spinning whenever possible, and when not, dismount and run, fast.

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.
