At A Glance
  • Fast, agile trail centre and big mountain hardtail mountain bike frame
  • Vertically compliant laterally stiff carbon frameset
  • Dropper seat post compatible
  • 650b+ boost compatible

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.

The 65 degree slack head angle is designed around a 130mm 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.

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 respond to hard riding. But mostly, they are to be ridden and enjoyed. Easy to ride and maintain, fast and lots of fun.

Vertical compliance and lateral stiffness

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 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.

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.
