The Transmitter Carbon is long, low, slack and fun.
Stability and control at high speed. Better stand over clearance. Climbs really well and makes the most of any traction.
..Read moreThe 65 degree slack head angle is designed around a 150 mm fork and a 35 mm 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.

A striking, flattened top tube gives vertical compliance and lateral stiffness, striking the perfect balance between agility and stability.

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.

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

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. 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
