    • 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.

      • 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 HG

      +£149.99

      • 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 cartridge 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.

      Built to take abuse

      Alphas have sealed bearings that are easily serviceable without the need for specialist tools. Double-butted spokes have been chosen to keep the wheels super-strong, whether you’re landing big drops or loading your bike with luggage. And a 17mm alloy axle make these hubs super-stiff and super-strong. You could race round the world on these wheels. Silk Road Mountain Race here we come!

      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 Black

      • 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.

Description

The Signal is fast, it’s 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 groomed descents at Llandegla and Glentress or take it to the big mountains and get loose.

At a glance
  • Fast and aggressive titanium 29er hardtail trail bike
  • Frame: Signal Ti aeronautical grade titanium frame, custom options available.
  • Fork: Rockshox Revelation RC / 29 / 130mm
  • Brakes: SRAM Guide T
  • Groupset: SRAM NX, 12 speed, 11-50
  • Rims: Love Mud Nova 29 Wheelset / Shimano
  • Clearance for up to 2.6" tyres

That low BB and long wheelbase gives a planted and stable feel through the corners and on 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 in wheels can be paired with 2.2 to 2.6ins tyres with clearance for winter conditions.

The titanium Signal frame is stiff, light and durable. 3Al 2.5V Aeronautical grade titanium tubing softens trail buzz and provides the engaging and lively feel that only Titanium can.

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

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.

Aggressive trail geometry

​Neil has designed the Signal Ti 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.

Guided internal cable routing

​Guided internally routed cables for a clean look and silent ride.

Titanium frame

Nothing looks quite so good as the famously resilient and durable titanium. Signal Ti’s aeronautical grade titanium tubing absorbs shock to soften the ride without any loss to feel or speed. ​

Custom available

​We can customise any aspect of our Ti bikes. Come to us with what you want and Neil will make it happen.

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 toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height. Generally we recommend:
Small
Riders between 5ft 2in and 5ft 7in
Medium
Riders between 5ft 6in and 5ft 10in
Large
Riders between 5ft 9in and 6ft 2in

It is possibly the best all-round trail hardtail that I've ever ridden, I wanted to be out riding on it all the time - that is the mark of a good mountain bike.

Singletrack Review the Sonder Signal Ti

You know that rock garden that you’ll happily hop into on your full bounce bike? Well, the Sonder will do it too, only you’ll probably lift the front end higher, get airborne further and completely clear the whole lot...
