    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.

    • Sonder Confucius

      +£19.99

    • 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.

    • Love Mud Aspect Flat 720mm

      +£0.00

    • Love Mud Aspect Flat

      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

    • Love Mud Abode

    • 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.

    • Love Mud Kura

      +£19.99

    • Love Mud Kura

      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.

    • Sonder Nova 29 [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.

      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

      26mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.2" - 2.6" 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.

      Tubeless Compatible

      The Nova 29's tubeless-ready rims mean you’ll be able to run lower pressures, giving you even better traction and control.

    • Sonder Alpha 29 [OEM]

      Alphas are our performance 29er wheelset for aggressive trail riding. Whether you're riding down Top Chief at Fort William or riding the black routes at Bike Park Wales, Alphas will consistently spin up to speed and keep rolling to help you ride with fluid precision over the trails.

      Alpha hubs: wider, stiffer, tougher, faster

      Alpha’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. To make them faster we’ve used a 6 pawl freehub, which gives 120 points of engagement for immediate response when you turn the pedals (most hubs only have 60, which means you have to turn the pedals further before engaging the freehub). Oh, and the hubs sound amazing! Finally, sealed endure bearings just keep rolling and rolling.

      Wider rims mean tyres work better

      30mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.2" - 2.6" tyres, which will plump up really nicely to give a broad contact patch for maximum traction and confidence.

      Alphas have sealed bearings that are easily serviceable without the need for specialist tools.

      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.

      Pedals: the humble yet essential afterthought that make all that time spent pondering over components worth the pain. Where would we be without them?

      Seriously grippy, reliable, and stable; Torque gives you the confidence to put down the power whatever the weather.

      A light and tough thermoplastic body combined with LSL sealed bearings around a CNC machined Cr-Mo makes Torque the kind of pedal you can depend on to withstand hours of use and abuse.

      Twelve 4 mm replaceable grip pins on each side of the pedal let you customise how much grip you’ll need and boost durability.

    • Sonder Slingshot

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

      The Slingshot's wide foot platform provides plenty of support to the foot for comfortable pedalling over long distance. 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 clip-in (or 'clipless' for the purists) system provides greater pedalling efficiency when climbing and more control when descending.

Description

Frontier is our multi-activity hardtail mountain bike. Ride hard at the trail centre, load it up for a midweek bikepacking trip, pocket your passport and continue around the world. With full rack mounts at the back and multiple boss mounts on the fork, Frontier is an adaptable off-road explorer.

The geometry is for long day comfort but it’s no slouch.

The 6061 aluminium frame provides a durable and stiff chassis giving a responsive kick as you demand power when the slope steepens or enjoy feedback and precision through the corners.

Available as a fully rigid or with 100mm suspension fork. Set it up for XC race speed or for all day big mile comfort.

 

Tyre clearance gives you the choice of 27.5+ or 29in wheelsets. Bolt through 148mm boost rear spacing provides the benefit of stronger, stiffer and more efficient wheels.

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.

Giving several centimeters of squish, their suspension-like characteristics help the Frontier float over rough terrain. With big handlebars, an upright position, and loads of stand-over, the Frontier is great for roistering about on, and could certainly serve as a regular mountain bike.

The 6061 aluminium tubing is durable, light, low maintenance and stiff.

Internal Cable Routing

Clean lines and tidy cables thanks to internal downtube routing. Frontier also incorporates routing for a dropper seat post.

Wide Tyre Clearance

Extra width between the chainstays gives you the choice of running 27.5+ tyres up to 3 inches or 29 inch tyres up to 2.5 inches.

Boost Axle Width

The Frontier frame is designed around bolt through Boost 148mm rear spacing providing the benefit of stronger, stiffer and more efficient wheels. Seatstay mounted disc brake for clean lines and damage protection.

Triple Bottle Cage Mounts

Fit 2 bottles in their standard location or run your downtube bottle cage a little lower to clear a bikepacking frame bag. Plus there’s an extra bottle cage mount under the downtube.

Pannier Rack Mount

​Seat clamp mounted pannier attachment points make fitting a rack easier and keep pannier rack rails free from twisting and warping.
