        Steel wilderness hardtail for big mountain days and fully loaded adventures off the beaten track. It's the perfect choice to tackle long distance point-to-points like the Tour Divide or the Atlas Mountain Race, eating up off-road miles day after day.

        High-quality 4130 chromoly steel tubing gives that coveted steel ride feel; lively and vibration-absorbing with all the capability of modern trail geometry. Optimised strengthening gussets at the headtube and bottom bracket add stiffness where its needed without adding excess weight - this helps maintain handling when carrying heavier frame bags or panniers.

        Optimised for use with 29" tyres; soak up uneven ground and enjoy a confidence-inspiring, stable ride at higher speeds. A long wheelbase and relaxed head angle strike the perfect balance between comfortable uphill grinding and hair-raising downhill whooping and make for efficient all-day riding over rough terrain.

        Build your dream rig with a full set of expedition rack mounts, we've designed the Broken Road to be loaded up with kit and pointed towards remote places. Highly durable and ultimately repairable; steel frames can take heaps of abuse even when you're carrying everything but the kitchen sink - offering peace of mind on multi-day trips and more technical trails.

        Why SRAM Eagle 90?

         

        First, we delivered the dream of the perfect mountain bike shift. Now we’re delivering the dream of ultimate performance for the mechanical mountain bike transmission too. 

        This is Eagle Mechanical Transmission. 

        The world’s first mechanical groupsets to use a Full Mount interface instead of a derailleur hanger. The first to let you shift anywhere, under absolute power, without compromising or compensating. It’s the world’s first mechanical system with incredibly easy “prepare, hang, tighten” installation, no adjustment screws needed. Rebuildable. Reliable. Affordable. Mechanical Transmission is the dream, delivered. 

        Hangerless Interface and Full Mount give the Eagle Transmission derailleur a remarkably strong attachment, clamping around both sides of the frame itself and eliminating the need for a hanger. This super strong connection eliminates variance and improper adjustment across frame designs. It also eliminates hanger failures and allows the derailleur to rotate backward in the case of an impact.

         

        "Please note: The above images are for illustration purposes only and may show alternative parts. The shipped bike will be built with the correct groupset and spec as outlined below.

        Features

        Trail bike geometry

        The long wheelbase combines precision and control, giving you the flexibility to adjust riding position easily. A relaxed head angle lets you cover rough ground efficiently, and strikes the perfect balance between comfortable uphill grinding and hair-raising downhill whooping.

        Traditional material. Modern Design

        High-quality 4130 chromoly steel gives you that coveted steel ride feel with all the benefits of modern trail geometry. Balance strength and stiffness with the lively, vibration absorbing nature of steel for comfortable all-day riding over rough terrain. Highly durable and ultimately repairable; steel frames can take heaps of abuse even when fully loaded with bags and kit, ideal for off-the-beaten-track adventures.

        Huge tyres. Endless grip

        Designed for optimum use with 29" wheels with clearance for 2.6" tyres. Soak up uneven ground and enjoy a confidence-inspiring, stable ride at higher speeds. Ideal for longer mile-munching day rides and multi-day off-road adventures. Broken Road can also take 27.5+ wheels with clearance for up to 3" inch tyres.

        Build your dream rig

        Triple mounts on the top and bottom of your downtube let you position your bottles high for easy reach, low to fit larger half-frame bags, or under the down tube to accommodate a custom Stingray full-frame bag. There's also a bottle mount on the seat tube and two sets of accessory mounts on the top tube, plus rear pannier mounts for those longer expeditions.

        Adjustable sliding dropouts

        Adjustable sliding dropouts give you the freedom to choose between single speed or derailleur setups. They'll also help you fine tune your setup to match your chosen wheel size and ride style.

        Internally routed cables

        Hidden cables keep the lines clean, and maintenance easy thanks to fully guided routing. Broken Road also has routing for a dropper seatpost.

        Geometry and Sizing

        Sizing

        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.
