Bombtrack AUDAX AL SWORD

The Audax AL Sword is an allroad bike designed for long miles, mixed surfaces and everyday reliability. Its lightweight aluminium frame with a T47 bottom bracket delivers a strong, responsive ride, while the full carbon fork with bottle cage mounts boosts versatility for endurance adventures.

Equipped with Microshift’s Sword 10-speed wide-range drivetrain and an 11 – 48T cassette, you’ll have all the gears you need for steep climbs and fast flats.

The clutched Sword rear derailleur with a replaceable cage ensures smooth, secure shifting, even on rough terrain. A Bombtrack Lyer 30 mm aluminium crankset with a 40T narrow-wide chainring adds durability and chain retention. Rolling on tubeless-ready WTB ST i21 rims with plush 650B x 47C WTB Horizon tires, the Audax AL Sword is ready for the road less travelled.
