BOMBTRACK Audax AL Road Complete Bike • Waller BMX

The Bombtrack Audax AL Road is the aluminium Audax for riders who prefer 700C wheels and close-ratio 2x gearing. It uses the same lightweight hydroformed frameset as the 650B version, with 700 x 34mm WTB Byway tyres for extra speed. Shimano's Tiagra 4700 drivetrain has a 50/34T chainset and 11-34T cassette, and TRP Spyre C flat mount disc brakes do the stopping.
