TECHNICAL INTERPRETATION
The Audax AL Road is supplied with 700C wheels and 34 mm tyres to maximise speed and rolling efficiency on tarmac and gravel roads. The clearance up to 35 mm in 700C allows slightly larger tyres for extra comfort and grip on long endurance rides.
Support for 650B up to 50 mm opens the door to a more comfort-oriented setup, ideal for riders who regularly ride on broken gravel, rough dirt roads or who simply prefer a more cushioned ride.
In practice, you can choose whether to emphasise the road character (700C × 32–35) or lean more towards allroad/comfort (650B × 47–50) depending on your primary use.

¹ The recommended bike size is a general guideline to narrow down options based on rider height. Proper bike fitting is complex and should also consider other body measurements and factors. Since no two riders are exactly alike, it’s impossible to provide a sizing recommendation that is 100% accurate for everyone. The best way to determine the correct size is to consult your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter.
