The Transmitter Carbon is long, low, slack, and fun.
We’ve taken what we’ve learned from the original alloy Transmitter and evolved the geometry, extending the reach, and lengthening and lowering the wheelbase to boost stability and control at high speed.
Designed to run plus-sized tyres, and with a 73-degree seat tube angle, Transmitter Carbon makes the most of every ounce of traction to take you up steep hills like a dream.
A shorter seat tube supports longer drop seatposts, giving better stand over clearance. Combine this with the relaxed, 65-degree head angle, and a flattened, longer top tube, and you’ve got a bike that gives you confidence and agility for an inspiring ride, whether tackling steep mountain trails or shredding the local woodland singletrack.
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.
Think of Transmitter Carbon as your friendly neighbourhood hooligan: a fast, aggressive, forgiving, and fun bike that just fits in with hard riding.
GX Eagle Drivetrain
Simple, light, tough, and reliable; the SRAM GX Eagle understands that when adventure is on the cards, all you want to do is put your feet on the pedals and ride. No faff.
The 12 speed, 10 – 50 tooth groupset combines easy-going versatility with maximum performance, giving crisp shifting, quiet operation, and silky smooth pedalling feel.
A super wide gear range lets you dictate your pace, whether you’re tackling tough inclines, sprinting on the flats, or letting loose on the descents. An open design facilitates mud clearance and boosts durability.
The GX crankset, with 2 tooth profile chainring, bolsters ultimate chain control, and Flowlink technology enhances chain guiding, increases longevity, and heightens wear resistance.
Vertical compliance and lateral stiffness
A striking, flattened top tube gives vertical compliance and lateral stiffness, striking the perfect balance between agility and stability.
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.
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.
