    Accessories

  • Fork

  • Handlebar

    • Sonder Aspect Flat 720mm

    • Sonder Aspect 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!

    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 Cambium C17 Saddle / All Weather / Black

      +£94.99

    • Brooks Cambium C17 Saddle [OEM] / All Weather / Black
    • 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.

    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.

      +£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 Jekyll Black

      +£59.99

    • 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.

    • Sonder Contact

      +£49.99

    • Sonder Contact

      The Contact are lightweight SPD-SL compatible pedals with a large contact area for energy efficient road riding.

      The Contacts have a large, stiff platform, improving power transfer for sprints and climbs and supporting your feet for all-day spinning in comfort.

      The bigger contact area of the SPD-SL system 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 keep the weight down to 148g per pedal, shaving vital grams from your drive chain.

    • 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?

    • 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

      +£24.99

    • 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.

    • Boson

      +£29.99

    • 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

      +£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

Santiago knows its heritage; cold-worked, air hardened steel is steeped in the history of long distance riding. But with bang up-to-date geometry, Santiago has a refreshing feel that you know will be good for years to come: 450 mm chainstays, 1.1 m wheelbase, 71 degree head angle, a fork rake of 55 and generous tyre clearance. This makes for a truly comfortable, fast, assured bike, both in its own right (audax slaying, winter riding) or when racked up for multi-month adventures.

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.

Features

Reynolds 631 steel tubing

Durable, smooth and assured on those multi-month trips Reynolds 631 steel is an excellent material for round-the-world touring where you’re completely dependent on your bike. We’d be surprised if you needed to get your frame repaired, but it’s comforting to know that finding a steel welder in the middle of nowhere is far easier than getting your alloy frame repaired.​

Traditional bike, contemporary geometry

Santiago’s takes classic road bike geometry as a starting point, with a longer wheelbase and higher stack height for a more comfortable riding position and assured ride, whether you’re travelling light or fully loaded up.

Generous tyre clearance

Clearance for up to 650b x 47 mm or 700c x 37 mm tyres that make your ride more comfortable and give better grip on the bitumen as you corner.

Full traditional mounts

With full rack and guard mountains, 3 sets of bottle cage bosses and extra cage mounts on the fork, Santiago can handle being fully loaded up.

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 toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.
