Transmitter Carbon is the evolution of the original alloy, designed for adrenaline fuelled aggressive trail riding and big days in the mountains. Transmitter carbon frame rides like the alloy but on steroids. Kind of like a friendly hooligan: aggressive, responsive and fast but fun and forgiving.

Transmitter Carbon frame at £749; complete bikes from £1499.

Contact us to arrange a demo at one of our stores or test ride over a weekend for £39 a day plus £30 delivery and return shipping.

The Transmitter Carbon is long, low, slack and fun. A plus sized carbon hardtail.

We’ve taken what we’ve learned from the original Transmitter and evolved the geometry, we’ve extended the reach and the long and low wheelbase gives stability and control at high speed.

We’ve shortened the seat tube length to allow longer drop seat posts and give better stand over clearance, the 73-degree seat tube angle and the plus size tyre specific design means it also climbs really well and makes the most of any traction.

The same slack (65-degree) head angle is designed around a 120mm fork and a 40mm stem. When combined with short seat stays and that flattened, longer top tube you get an agile and confidence inspiring ride whether riding steep mountain trails or shredding the local woodland singletrack.

Transmitter Carbon makes best use of available technologies. Boost 148/110 standards and bolt through hubs mean a stiffer and more responsive ride.

650b+ tyres on a tubeless compatible wheelset mean loads of grip and control, whether climbing or descending.

We’ve stuck with a standard threaded BB because we think it works better for where we ride, year round.

Transmitter Carbon frames are designed around 1x specific groupsets and feature internally routed cables, integrated headsets, stealth dropper routing and a single set of bottle bosses.

The Transmitters are bikes that just fit in with hard riding. But mostly, they are to be ridden and enjoyed. Easy to ride and maintain, fast and lots of fun.

Sonder Transmitter Carbon - Need to know

Extended reach

Transmitter Carbon is an evolution of our original alloy Transmitter. We’ve made a few tweaks here and there, and extended the reach to enhance stability at higher speeds.

Internal cable routing

Clean lines and tidy cables thanks to internal routing. Transmitter Carbon also incorporates a neat Reverb Stealth port for a dropper seat post.

Boost 148-specific design

Transmitter Carbon is designed around Boost 148 standards and 650b+ tyres, even the most sheepish rider will tackle those steep sections like a pro. Seatstay mounted disc brake for clean lines and damage protection.

Precision engineering

Long wheel base, slack head tube, low belly, and room for plus size tyres.

Wide tyre clearance

Extra width between the chainstays lets you run 27.5+ tyres up to 2.8 inches.

Obsessive detailing

Precision decals, a choice of raw carbon finish, and 2 painted colourways.

Sizing

It is important to get the right size bike, if the bike fits you well 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.
