Audax AL Road
"The perfect companion on any number of adventures, it’s fast-rolling, yet proficient on broken surfaces."
Bombtrack Audax AL Road
Our Audax aluminium 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.
