The off-road adventurer.
Plush 650b+ tyres will rapidly steam roll over everything with a corner grip that will make a muddy WRT a breeze.
The slackened angle gives the perfect balance of comfortable uphill grinding and exciting downhill whooping. Longer wheelbase wonderfully balances precision and handling.
Wide, ovalised top tube gives vertical compliance but lateral stiffness -this also makes it easier to keep your luggage in place when riding over rough ground.
Broken Road’s titanium frame is designed for optimum use with 650b/650b+ wheels but can be swapped out for 29ers to help you tackle any journey that you thrust upon it. The bigger, fatter wheels go over obstacles better, hold momentum and give enhanced control due to the angling.
Why SX Eagle?
SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.
SX Eagle provides the same Eagle performance benefits as NX Eagle, but at a lower price point. The main differences stem from the choice of materials and finish options, but functionally SX is fully compatible with SRAMs Eagle groupset.
Elegant titanium tubing
Climb aboard and experience the famed resilience of titanium. No other material is as durable, lasts as long, or looks as good, and Broken Road’s aeronautical grade titanium tubing isolates the rider from shock, gives an efficient ride, and maximizes storage potential. Thanks to the low standover height and rider clearance, you won’t have to make any compromises when riding over rough terrain either.
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.
Titanium is lightweight, strong and durable make it an ideal construction material for bike frames. No other material is as durable, lasts as long, or looks as good. Our frames are handmade and come with a 10 year frame warranty

Reach dimension is static with 470 mm fork. Suitable for 470-480 mm fork, or 80-100 mm 29er suspension, or 100-120 mm 650B. Frame is designed to run a short stem – between 35 mm and 50 mm. Also works great with a 26” fat bike front wheel
It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the top tube to your crotch this will give you enough seat post adjustment to find your optimum saddle height.
