    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 Love Mud 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 offroad 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. Need some bar tape? Add a couple of rolls of Love Mud Reels for better comfort and grip.

      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 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.

    • Sonder Alpha 27.5 HG

      +£149.99

      • Sonder Alpha 27.5 [OEM]

      Alphas are our performance 27.5” wheelset for big hits and big tyres. 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.

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

      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

      35mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.4" - 3" 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. 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 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!

      The Sideblade bottle cage not only gives your water bottle a lovely, secure hug, but its side loading system makes it easier to access when you need a drink, making staying hydrated a joy even when you've got a load of frame bags to work around!

      The Side blade is geared at letting you get to your water when you've got a bike packed up with frame bags, this means that it's also ideal for compact and full-sus frames where a standard loading bottle cage system just won't fit, you can choose which side you'd like to access your bottle by with a twist of the cage in the mount before your ride.

      Made of polycarbonate, the Sideblade is also super light and super duper tough - hooray!

This lightweight plastic mud guard keeps splashes and spray off your back and doesn’t need any special fixings to attach to your bike.

Description

The signature flattened top tube gives vertical compliance but lateral stiffness - it really is an all mountain bike. That long wheelbase combined with the slack front end, size specific chainstays and a lowered BB give stability and control through the rowdiest of terrain.

Transmitter is designed around Boost 148/110 standards and 650b 2.6/.8 tyres, and optimised for 1x groupsets. The geometry and extra grip from those big tyres means even the most sheepish rider will tackle those steep sections, up and down, like a pro.

Transmitter frames now feature internal cable routing through the downtube, integrated headsets, through-axle hubs, refined dropouts, butted tubes and smooth welds (and 3 shiny new colours).

Transmitter is a bike that just fits in with hard riding. This new version is still the fun trail bike it’s always been, and will still be a perfect partner for multi-day epics or short and fast trail centre blasts, but the changes we’ve made have raised the Transmitter’s limits, so you’ll be able to push the bike harder than ever before!

At A Glance
  • Fast, agile trail centre and big mountain aggressive hard tail.
  • Frame: Sonder Transmitter, hand-welded 6061-T6 triple butted frameset_x000B__x000B_; vertically compliant laterally stiff tubing.
  • Drivetrain: SRAM NX / 1 x 12 / 11-50
  • Brakes: SRAM Guide T
  • X-Fusion Manic Drop Seatpost and Lever / 31.6mm / 150mm
  • Forks: Rockshox Revelation RC / 27.5 / 150mm
  • Wheelset: Sonder Nova 27.5+ Wheelset / Shimano
  • Tyres WTB WTB Vigilante / Comp / 2.8 (front) and WTB Trail Boss / Comp / 2.6 (rear)

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.

Off Road.cc Review Sonder Transmitter NX Eagle

The Transmitter is a playful, all-mountain rig with some hooligan tendencies. It suits all manners of riding from trail centres to more natural riding to exploring wild bridleways. If you want a ‘one-hardtail-does-it-all’ then the Transmitter will do that in spades.

Singletrack take a first look at the new Transmitter

If you’re a numbers nerd or geometry geek you’ll recognise that while these are significant changes, they aren’t all that extreme and should result in a well rounded riding machine rather than something that only rides in one direction.

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
X-Large
Riders of 6ft 2in +

Features

Hand welded 6061-T6 triple butted frameset

Not all tubes are equal, Transmitter uses tube walls of different thicknesses to get material where it is needed and save weight where it isn’t.

Dropper seatpost ready

The Transmitter frame is compatible with a dropper seatpost so even the most sheepish riders can tackle those steep sections head on like a pro.

Vertical compliance and lateral stiffness

The strikingly flattened top tube is the spoonful of black magic we need to make the frameset both rigid and forgiving in all the right places. Stable yet nimble, the geometry has been tweaked to give a spirited ride.

Internal cable routing

Clean lines and tidy cables thanks to fully guided internal routing.

Wheel compatibility

Designed around Boost 148/110 standards and 650b 2.6/.8 tyres

Chain guide ready

​Transmitter can be fitted with a chain guide. (ISCG 05 compatible).
