Sonder Broken Road frame and Rumpus wheelset

Build up your own ultimate adventure bike with this titanium frame and 650b+ wheelset

Custom titanium hardtail mountain bike suited for wilderness rides and remote places. A companion for a lifetime of adventure. Yet its slack geometry makes it a capable trail hardtail in its own right. Broken Road comes into its own chewing up off-road miles with finesse, a real mile-muncher. Race the Great Divide, ride across New Zealand or summit high passes in Nepal

For adventures into the remote, Broken Road will be an indispensable companion. Simple, elegant lines, mixed with technical details and features. Broken Road mixes adaptable wheel standards, adaptable drivetrain standards, and yet stays bang up to date, with modern features and contemporary geometry.

From it’s 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.

Broken Road is designed to work across any terrain, but if you want to mix things up, a short travel suspension fork or alternative front end package – even a fat bike front wheel, will add it’s own style and features.

Our adjustable dropouts allow fitting of various sizes of wheels (we recommend 650b+ and 29in or larger section 700c). The bigger, fatter wheels go over obstacles better, hold momentum and give enhanced control. There is flexibility in the choice of drivetrain as well, either singlespeed, conventional derailleur or internal hub gears.

Broken Road is the off-road adventurer. The one who, without engines and cacophony, can explore the world in a remarkably unique way. The ability to travel further, faster and with less gives the bikepacker a profound advantage. When you catch nature off guard, what will you see?

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.

Adaptable standards

Broken Road mixes adaptable wheel and drivetrain standards so you can ride it how you want. The adjustable dropouts allow 650b+ or 29 in wheels, and either singlespeed, derailleur, or internal hub gears.

Rear rack mount lugs

Rack mounts allow you to load up with panniers.
