TENSION
Our ‘standard’ model is anything but, using everything we have learned from our elite racer Gosse van der Meer’s race bike. The Tension offers a lightweight aluminium frame and full carbon fork with mud-friendly SRAM Rival 1x transmission and 160 mm hydraulic brakes. We’ve fitted race legal 32 mm XCX Vee tyres on the 650B XS - S sizes and 33 mm Schwalbe X-one Allround tyres on the M - XL models. The frame has rack and fender mounts and the cassette is a little more versatile with its wider ratios should you wish to use it for bikepacking rides or everyday commuting. No one says you have to race all the time - just at the weekend, right?

"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.
