"Blisteringly fast, sweetly detailed, radically dialled and still a total bargain" bikeradar.com
Carbon is light, strong and responsive. Its stiffness means more power from pedal strokes and sharper handling. Long low and slack geometry, plus, carbon hardtail. Built for the latest 1x gearing. Ovalised top tube for vertical compliance and lateral stiffness. Internal cable routing for clean lines. Tight chainstays. 650b+ boost standards.
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 dialled in 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 130mm fork and a 35mm 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.
“Blisteringly fast, sweetly detailed, radically dialed … a proper aggro attack bike that loves to shove its big front tyre into trouble and then bosses it out big style” - Guy Kesteven, Bike Radar
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.
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.
Fully guided internal routing
Clean lines and tidy cables thanks to fully guided 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.
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.
Precision decals, a choice of raw carbon finish, and 2 painted colourways.

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.
Generally we recommend:
- Riders between 5ft 2in and 5ft 7in
- Riders between 5ft 6in and 5ft 10in
- Riders between 5ft 9in and 6ft 2in
