    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.

    • 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.

    Seatpost

    • X-Fusion Manic Drop Seatpost and Lever 31.8mm / 125mm

    • X-Fusion Manic Drop Seatpost and Lever

      The X-Fusion Manic Dropper has been designed to work well across cross-country, trail, all mountain and enduro riding.

      It works on a simple design. Inside you’ll find a closed cartridge that is both sealed and designed to be easily removable from the rest of the post. Simple construction aside, the action of this post feels super-smooth and silky.

      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!

      Keep the dirt out your eyes so you can focus on the important things, having a great ride.

      If you don’t have the muddy equivalent of a duck's back then the Love Mud Rear Fender is the perfect product for you.

This lightweight plastic mud guard keeps splashes and spray off your back and doesn’t need any special fixings to attach to your bike. Simply fitted to your seat post and with a couple of ties under the saddle. You can pop it on your bike with minimal fuss and you’re ready for even the wettest ground.

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!

Bike Radar Transmitter Review

A great blend of swaggering, speed-breeding stability sharpened up by instantly reactive, traction-chasing, short stem steering .... Alpkit resets expectations with its new hardtail.

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.

What Mountain Bike 5* Transmitter

Genuine game changer .... crazily capable, radical geometry, hardcore hardtail that maximises the control and speed ... outragously good value ... reset our definition of cost-effective bike performance .... very very nearly saw Sonder take the overall win.

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).
