    Accessories

  • Handlebar

    • Sonder Aspect Riser 780mm

    • Sonder Aspect Riser [OEM]

      In general riser bars tend to be wider than flat bars and may have slightly more flex to give a more forgiving ride. As you go into descents and your arms drop below your knees the additional height gained on your front end will help you take control of the steep descents.

      That said you can get all bar types in a range of widths and stiffnesses and front end height can be adjusted with spacers like our Sonder Rings, so sometimes you just have to ignore the mumbojumbo and make your call on style and personal preference and there is nothing wrong with that.

    Saddle

    • Love Mud Abode / 138

    • Love Mud Abode [OEM]

      High density foam padding over a plastic base provides comfort and longevity. A v-shaped split at the rear of the saddle allows flex as you are riding, increasing shock absorbancy and reducing pressure on the spot between your sit bones.

      Scooped up at the back with a slight rise towards the nose the longitudinal profile provides a cupped, craddled seating position, a timeless, proven design for distance on and off the road or climbing in the mountains.

      Stainless steel rails give 50 mm of forward and back adjustment to help you find your sweet spot.

      All our Sonder bikes come with Abode fitted as standard.

    • Sonder Zone 133 / Black

      +£24.99

    • Sonder Zone [OEM]

      The Zone is designed for maximum pedalling efficiency and comfort on longer rides, whether on road or off it.

      • Chromoly rails with suspension system
      • Cut-out shape relieves pressure
      • High density foam seat for comfort

      We’ve selected a flat saddle profile that’s long enough to allow for lots of micro-adjustments to your riding position over the course of a full day on the bike. The nose width allows you to move forward over the pedals on climbs and sprints, and a tapered back enables you to get behind the saddle easily for switchback descents or technical off-road sections.

      We’ve chosen a nylon fibre saddle base to provide a stiff and stable pedalling platform for a low overall weight. This base is connected to the chromoly rails using a patented suspension system that reduces road buzz and improves comfort without compromising on support.

      High density foam stays comfortable for longer, adding to the saddle’s supportive platform. And a long central cut-out in the middle of the Zone relieves pressure on the perineum, allowing you to ride for longer.

    • Sonder Kura

      +£19.99

    • Sonder Kura [OEM]

      Adventure cycling is diverse; in the course of a single trip you can find km's of asphalt, traverse rutted grasslands, weave through thickly forest singletrack, climb loose gravel track or descend steep rocky trails.

      It is unlikely you are going to find a single saddle position for all of this terrain. With this in mind Kura has a flat longitudinal profile with a gentle lateral curvature to give an extended saddle area, allowing you to position yourself around the saddle as you move between road, downhill, and climbing.

      The honeycomb base reduces weight whilst still providing structure and support that adapts and flexes with your motion.

      Titanium rails giving 50 mm of forward and back adjustment to help you find your sweet spot. Titanium is more forgiving than steel so provides a little more comfort.

      Slightly wider than our Adobe saddle, it may provide additional comfort for riders with wider sit bones.

    • Brooks Cambium C17 Saddle All Weather Carved / Black

      +£69.99

    • Brooks Cambium C17 Saddle

      Not the chafe. The dreaded chafe. Once it begins, there’s no stopping the creep along your bum cheeks, every slight movement adding to the sting.

      Banish bum cheek blues with the Cambium C17. Based on the underlying structure of the classic Brooks B17 leather saddle, the Cambium C17 uses a vulcanised rubber base and organic cotton canvas upper for the top. Unlike leather, the top material is waterproof, completely maintenance-free, and eliminates the wearing-in process of a leather saddle.

      The saddle top is hung over the nose piece, rails and rear metal cantle like a hammock. This design, when combined with the saddle’s supple materials, allows the saddle to move with the rider, reducing chafing whilst still providing support. The C17 Cambium is narrower and a little racier in design than the B17.

    • Brooks B17 Saddle Standard / Black

      +£64.99

    • Brooks B17 Saddle

      Manufactured in the UK, a tough 5mm thick leather top is stretched from a thin metal cantle plate at the rear, over the rails to the nose piece and secured by rivets. This durable leather top eventually wears to the shape of the user’s ‘sit bones’ for a superior riding experience. With the right leather-care a Brooks saddle can easily last a lifetime of riding.

      It may seem counterintuitive, but firm and less cushioned saddles are proven to reduce friction while cycling which protects against chafing and rubbing. Should the hammock-like design of the saddle start to sag too much, the leather can be re-tensioned by tightening a bolt in the nose piece.

    Seatpost

    • Sonder Seatpost 31.6mm / 400mm

    • Sonder Seatpost [OEM]

      A seat post that is reliable and offers adjustability to help you find your ultimate riding position.

      Membar is all about adjustability. With a twist of your allen key the micro adjustment rail clamp allows the saddle angle to be fine tuned to your ideal position.

      Your saddle can be fitted with minimal faff thanks to a quick release action that allows the upper rail clamp to be released without removing the retaining bolt. The lower rail clamp is secured to the seat post which means that it will not fall in the mud when you are trying to fit your saddle.

    • X-Fusion Manic Drop Seatpost and Lever 31.6mm / 125mm

      +£119.99

    • X-Fusion Manic Drop Seatpost and Lever

      The X-Fusion Manic Dropper has been designed to work well across cross-country, trail, all mountain and enduro riding.

      It works on a simple design. Inside you’ll find a closed cartridge that is both sealed and designed to be easily removable from the rest of the post. Simple construction aside, the action of this post feels super-smooth and silky.

    • RockShox Reverb / 125mm Drop / 31.6 x 390mm

    • Cane Creek EE-Silk 31.6mm / Alloy

      +£179.99

    • Cane Creek EE-Silk [OEM]

      Ride longer, ride further with the Cane Creek eeSilk suspension seatpost.

      At 295g the eeSilk Post is comparable in weight to traditional rigid seatposts while offering 20mm of vertical compliance to help improve control on rough surfaces and reduce fatigue on long rides. It's the sort of upgrade you thank yourself for 6 hours into a ride!

    Wheels

    • Sonder Nova 27.5+ Wheelset Shimano

    • Sonder Nova 27.5+ [OEM] Wheelset

      Whether you're navigating rock gardens or tackling steep climbs, Novas will consistently give you a boost when the roads are rough and the terrain is tricky. Machine built for precision on Sonder’s sealed hubs.

      Our design team’s expertise along with the factories we use mean that we can accelerate trickle-down technology to this price point.

      Boost: wider, stiffer, tougher

      Nova's boost hub is wider than a standard hub; extra width between the flanges promotes a shallower spoke bracing angle to create a stronger, stiffer wheel. A wider hub also means a shorter chainstay, more mud clearance, and better tyre clearance.

      Wider rims mean tyres work better

      38mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.6" - 3" tyres, which will plump up really nicely to give a broad contact patch for maximum traction and confidence.

      Built to take abuse

      Novas have sealed bearings that are easily serviceable without the need for specialist tools. Plain-gauge spokes have been chosen to keep the wheels super-strong, whether you’re landing big drops or loading your bike with luggage. And a steel free-hub body will take years of abuse. You could go round the world on these wheels.

  • Pedals

    • No Pedals (none)

    • No Pedals
    • Sonder Reko

      +£50.99

    • Sonder Reko

      The Reko are lightweight SPD pedals designed gravel riding and cross-country mountain biking over longer distances.

      The Reko's platform-free design reduces the overall weight of the pedals to 145g per pedal for lighter, faster riding. Double-sided SPD bindings are easy to clip in and out of and their compact design means they're less likely to clog with muck on filthy winter rides.

      The clip-in design improves the efficiency of your pedal strokes, saving energy on long rides and improving power transfer on climbs, and gives you more control of the back end of the bike.

    • Phase / 400

      +£19.99

    • Phase / 400

      The Phase 400 is our lightweight, yet durable, rechargeable bike light for a midweek evening blast on the bike.

      • 5 lighting modes and a 200m beam distance
      • Versatile: can be attached to handlebar, helmet or cockpit mount
      • Rechargeable Li-ion battery, with micro-USB cable

      Say hello to our sleek, new bike light range: they’re light, durable and rechargeable (and they say hi back). At just 123g, the Phase 400 is the final tool you need to make the most of evening rides. With 400 lumens and >200m beam distance, a Phase bike light will keep you company and confident on your dusk rides.

      The Phase 400 has been made with the roadie in mind: whether you’re on a family ride, a mid-week spin or your daily commute to work, you’re going to need an all-round bike light for the incoming dark evenings. But don’t worry if you end up on a canal path or a gravel track, this rechargeable light will suit you just fine for a short jaunt off-road.

      Flick between 5 lighting modes: high, mid, low, SOS and strobe. The Phase 400 has a maximum battery life of 8 hours and 20 minutes in low mode, so in the case of a surprise night-time emergency, you’re sorted. The 80-degree beam angle ensures you can see and be seen.

      We’ve added in some nifty features, including memory lighting. The light will remember the most recently used mode and default to it the next time you head out on your bike. The Phase 400 is compatible with a handlebar mount (included), a cockpit mount and a helmet mount. It also conveniently charges with a versatile micro-USB cable.

    • Phase / 800

      +£29.99

    • Phase / 800

      As the Phase 800 is especially designed for easy-going gravel paths, canals, and short singletrack trails, it is perfectly suited to the gravel rider. The 85-degree beam angle means you can see the journey ahead, as well as be seen by oncoming traffic or the local gravel gang. 

      • >200m beam distance for dusk riding
      • Up to 18 hours of battery life
      • Memory lighting: the light defaults to the most recently used mode upon restarting

      The light boasts 5 modes: high, mid, low, pulse and strobe. In high mode, the Phase 800 lasts 1hr20mins – just enough time for your local mid-week, pre-dinner loop. On the other end of the scale, the 100-lumen pulse mode lasts over 18 hours! No matter your journey, Phase 800 can adapt to your trail.

      It’s got good memory too: the Phase 800 remembers your most recently used mode and defaults to it the next time you turn it on. Once you’ve finished shredding up the local gravel, don’t forget to recharge your light. It just needs a handy micro-USB cable to be ready for when you’re next raring to ride.

    • Hadron

      +£69.99

    • Hadron

      At a whopping 1,800 lumens, the Hadron shines like two twin suns on the front of your bars, allowing you to ride at daytime speeds long after the light fails.

      • Max power of 1,800 lumens with a wide beam angle
      • 6 different lighting modes to tailor to your riding
      • Remote control for swapping between modes at speed

      The Hadron uses twin Cree LEDs to provide a wide, bright beam that stretches well over 200m. This provides a ridiculous amount of night-time visibility so you can tackle tight and twisty singletrack at speed. It also comes with an optional remote control, allowing you to easily swap between lighting modes without needing to take your hands off the brake levers.


      With 6 different lighting modes, the Hadron’s brightness can be effectively tailored to your ride length, terrain and light levels. The lowest brightness Pulse mode runs for a massive 50 hours If you need to save battery on the roads or smoother sections. Plus, the twin bulbs are much more energy efficient than single bulb set-ups.


      The Hadron is housed in a durable 6063 alloy casing to protect your light from crash damage and an IPX6 rating is sufficiently waterproof for all-weather riding. An output jack on the Hadron means you can also use its large 6,700mAh lithium ion battery to charge your GPS or phone if you find yourself out of juice on mid-trip.

Description

Multi-day titanium expedition hardtail designed for big mountain days and fully loaded adventures.

Plush 27.5+ 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 27.5+ 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 SRAM's Eagle groupset.

Features

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.

27.5+ ready

Designed for optimum use with 27.5+ (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 27.5+ or 29” wheels, and either singlespeed, derailleur, or internal hub gears.

Rear rack mount lugs

Rack mounts allow you to load up with panniers.

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.

Medium: Riders between 5ft 6in and 5ft 10in
Large: Riders between 5ft 9in and 6ft 2in
