AUDAX AL ROAD

Our Audax Aluminium Road model is for lovers of 700C wheels and 2x close ratio gearing systems. Featuring the same lightweight hydroformed frameset as the 650B version with all the same benefits and accoutrements to help you carry your kit, but now with extra zip from the 700 x 34 mm WTB Byway tyres - what they give up in volume they deliver in speed. Shimano’s Tiagra 4700 drivetrain complete with a 50 / 34T chainset and 11 - 34T cassette helps to keep your cadence super smooth and TRP Spyre C flat mount disc brakes deliver all the stopping power you could ask for. The perfect bike for long-distance efforts against the clock.

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.
