For adventures into the remote, Broken Road is your friend. Simple, elegant lines, mixed with technical details and features. Broken Road mixes adaptable wheel and drivetrain standards with modern features and contemporary geometry.

With its multi-use tyre size – from big 27.5+ tyres to 29in rubber to 700c wheels, Broken Road eats up long distance trails with style and comfort whilst being a capable trail centre hardtail. Hand welded from the finest 3AL / 2.5 V titanium tubing, custom formed and designed by us to be your tool of choice for eating up the miles over whatever surface you choose.

Adjustable sliding dropouts let you lengthen or shorten the Broken Road to suit your adventure - whether it’s eating up big miles or tackling technical trails. It also allows lets you fit various sizes of wheels (we recommend 650b+, 29in or larger section 700c). The bigger, fatter wheels go over obstacles better, hold momentum and give enhanced control. The dropouts let you be picky with your drivetrain as well, fitting singlespeed, conventional derailleur, or internal hub gears.

Broken Road is the off-road adventurer.

650b+ ready

Designed for optimum use with 650b+ (semi-fat) wheels which help you to tackle any adventure. The plus-sized wheels cruise over obstacles, hold momentum, and give enhanced control thanks to a larger contact patch.

Trail bike geometry

The long wheelbase combines precision and control, giving you the flexibility to adjust riding position easily. The frame is designed with a relaxed head angle, creating the perfect set up for eating up the miles over any surface, and striking the balance between comfortable uphill grinding and hair-raising downhill whooping.

Adjustable sliding dropouts

Adjustable sliding dropouts let you lengthen your Broken Road for eating up the miles or shorten it for the technical, steep trails, and allow for either 650b+ or 29” wheels, and either singlespeed, derailleur, or internal hub gears.

Rear rack mount lugs

Rack mounts allow you to load up with panniers.
