    • 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.

    • Sonder Horizon Flat 720mm

      +£0

    • Sonder Horizon Flat [OEM]

      Flat bars help you keep the front end of your bike low, allowing you to get the weight over your front wheel when climbing and giving you more control in cornering.

      Our flats have a 5˚ rise so technically we should call them flatish, but if you really need them to be totally flat just rotate in the stem clamp!

    • Sonder Confucius

      +£24.99

    • Sonder Confucius

      Confucius says that you don't have to sacrifice what you love about your traditional riser bars just to get the flexibility of a hooped bar.

      We have taken our Aspect risers and evolved them in to a bar designed primarily for bikepacking. You won't have to adapt to a new hand position so you are not going to lose any control off-road and you can still get out of your saddle and power up the hills like a hero.

      If you do want to move your hands a bit a reduce the fatigue of a long ride, the hoop extends out front giving a choice of further hand positions. The bars also have a slight 'back sweep' so you can sit more upright in the saddle

      The bars have a slight riser but feel free to experiment and rotate them to your suiting. Keep them horizontal, or twist them up slightly to give yourself a streamlined TT style riding position to help you battle across a windblown Tierra del Fuego.

      Strength is not compromised as the main load bearing section of the bar is a single piece. Got gadgets? Confucius loves gadgets, and with the out-front hoop you can free up the bar around the stem. Simply attach your Garmin, 3000 lumen torches or mascots to the hoop and they will still be well within reach, maybe at an even better viewing angle and sit above your handle bar luggage.

      Take your bikepacking into the mountains; Confucius is a bar that gives you more control than a tradional swept back bar on technical terrain.

    Saddle

    • Sonder Abode Black / 138

    • Sonder 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

      +£29.99

    • 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

      +£34.99

    • 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 B17 Saddle Standard / Black

      +£109.99

    • 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.

    • Sonder Contact

      Contact are lightweight clipless pedals compatible with all Shimino SPD-SL cycling shoes. Contact has a large platform for energy-efficient road riding. They're stable and secure particularly your cadence increases or climbing 20% gradients or more.

      They have a large, stiff platform, and easy to get on with improving power transfer for sprints and climbs and supporting your feet for all-day spinning in comfort.

      To clip into pedals, you step on the pedal’s face and push your foot forwards or downwards to engage the cleat. To release your foot, simply rotate it outwards. They're ideal as a first clipless pedal, or anyone looking for an affordable pedal that has high-end tech.

      The bigger contact area of the SPD-SL system means stable and secure pedalling and it is more energy efficient too, preserving your legs for those deceptively savage inclines at the end of your ride.

      The thermoplastic body and fibre-glass-reinforced binding is durable but keeps the weight down to 148g per pedal, shaving vital grams from your drive chain.

    • Sonder Torque Black

      +£29.99

    • Sonder Torque

      A tough large platform, thin profile thermoplastic body with replaceable steel pins. The Cromoly axle gives durability and strength that you can depend on.

      LSL bushing combined with a sealed bearing keeps the pedals turning in all weather conditions.

      We have tried and tested these pedals and they have stayed true through winter and summer trails.

    • 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.

    • Sonder Distortion

      +£54.99

    • Sonder Distortion

      Sonder Distortion is a tough, solid, high performance flat pedal that won’t let you down. These are our team favourites and the pedal that designer Neil Sutton raves about. Pedals that equal the best, it's a large platform, thin profile pedal designed to be ridden hard in the worst conditions.

      A CNC-machined, light and durable 6061 aluminium body takes use and abuse day-in, day-out. The Cromoly axle gives durability and strength that you can depend on.

      Replaceable, double-sided (4.5/6.5 mm) steel pins are more than capable enough to take a beating on the trails without leaving you threading out the remnants with your pliers at the end of the day. Let’s face it, who wants that after a day round the trail?

    • Sonder Jekyll Black

    • Sonder Jekyll

      Jekyll is two faced; SPD's and flats all in one, multi-purpose mtb touring pedals.

      Jekyll gives you the freedom to ride with normal shoes or with cleats. Jekyll combines a single sided SPD mechanism with a flat pedal body with grip pins on the other. They are ideal for riders who switch frequently from the daily commute to nipping down to the local shop for a pint of milk in their loafers.

      The flat side has 8 replaceable grip pins, 4 mm long, they provide grip in all conditions. When you are ready to get your power on the cleats are just a half rotation away - no swapping your pedals out.

      Jekyll also comes provided with Sonder 'SH-51 style' cleats.

    • Sonder Slingshot Black

      +£59.99

    • Sonder Slingshot

      The wide platform Slingshot pedal is designed to provide the support, control and confidence you need for a variety of riding, whether on trail, gravel or road.

      • Wide 87x90 platform made from 6061 aluminium
      • Double-sided adjustable SPD clips
      • Chromoly axle with sealed bearings

      The Slingshot's wide foot platform provides plenty of support to the foot for more comfortable pedalling over long distances, reducing hot-spots. This additional foot support also gives you greater control of the rear end of the bike on tight turns or technical trail.

      If you're using the Slingshot for mountain biking, the pedal's wide surface gives you a platform to stand on unclipped, ready to bail out if needed, on heart rate-quickening sketchy sections.

      With double-sided SPD clips and a large pedal area, the Slingshot is easy to clip in and out of in a hurry. A clipless system provides greater pedalling efficiency when climbing and more control when descending.

      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.

    • Boson

      +£24.99

    • Boson

      A powerful bike light with tough aluminium shell suitable for mountain biking and road biking. Boson is small and compact with a Li-ion rechargeable battery and a Micro USB port.

      Boson has 5 lighting modes which are cycled through (excuse the pun) with a single illuminated switch. High power pumps out 850 lumens making even the darkest commute a tunnel of light. Turn it down to medium power and you still have 320 lumens to play with - more than enough for negotiating un-lit cycle ways and paths.

      If you want to be seen rather than see where you are going switch out to the 6 or 3 Hz flashing modes. Bright enough to be seen even during daylight hours, it really comes into its own during the hours of twilight and dusk.

      A mounting bracket is included (fits 18 - 36 mm bars and no special tools needed). Once attached Boson can be fixed or removed with ease. It allows 360 degree rotation for complete control over your beam of light; the textured lens projects a smooth wide beam ideal for nocturnal riding.

      Note: Boson doesn’t take a "standard" 18650 battery - the battery has both anode and cathode at the same end. Do not switch on Boson during charging as it could damage the battery.

    • Hadron

    • 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

Signal ST

The Signal is for flat out speed.

It pedals like an XC bike, descends like an enduro bike, and captures the rawness of riding a hardtail on fast, flowy singletrack. Stand up, sprint, and ride it hard on the groomed trails at Llandegla and Glentress or take it to big mountains and let loose.

That low BB and long wheelbase gives a planted and stable feel through the corners and when tackling high speed descents. The low stack height leaves you with less of that ‘tall’ 29er feeling – you’ll feel like you’re 'in' the bike, not on the bike.

Big wheels roll faster. The 29" wheels can be paired with 2.2 to 2.6in tyres with clearance for winter conditions.

The Signal Steel rides beautifully – it’s got that distinctive steel feel to take the edge off the biggest hits while keeping stiffness where it counts so you can accelerate out of corners and track accurately through rocks and roots.

Neil's take

I find NX Eagle to be the sweet spot between performance and price. You're getting a lot of the benefits of GX Eagle mixed with some of the value of SX. It's a real Goldilocks groupset.

Then, chuck in the excellent Pike forks, which give you great control over the rough stuff, a dropper seatpost, to help you fly down the trails, and our lightweight, performance Alpha 29" wheels, that spin up quick and roll smoothly, and you've got a build that'll ride beautifully.

Why NX?

SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is a solution that is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.

NX Eagle provides the same Eagle performance benefits as the rest of the Eagle family. Slotting in just under the higher priced GX, the main differences are extra weight and the 11-50 range is not as wide as the 10-50 offered with GX, but functionally NX is 12-speed and fully compatible with SRAMs Eagle groupset.

Features

Aggressive trail geometry

​Neil has designed the Signal St to suit his aggressive riding style. A low bottom bracket makes it corner like its on rails, a spacious reach gives you room to move around on the bike, and the 66/74 head and seat angles give you the confidence to bomb the descents and while still being able to climb like a mountain goat.

Steel Frame

Nothing feels quite so good as the famously springy and durable Steel. Signal St’s 4130 Chromoly, Hand Welded Steel tubing absorbs shock to soften the ride without any loss to feel or speed.

2.6” tyre clearance

​Bucketloads of clearance for 2.6” tyres gives you the benefits of higher volume tyres without getting clogged up in UK conditions.
