  • SRAM XX1 Eagle, 1 x 12 groupset giving a 500% gear range
  • Rockshox Pike RCT3 650b+ boost forks
  • Reverb dropper seat post
  • Love Mud 650b+ boost wheelset with WTB Trail Blazer tyres
  • Hand welded 6061-T6 triple butted frameset
  • Vertically compliant laterally stiff tubing
  • Fast, agile trail centre and big mountain hard tail mountain bike

Transmitter: aggressive 650b hardtail mountain bike for taking on trails guns blazing; Snowdon on a sunny Autumn day or the Colorado singletrack. Yet, you can still whip around Cannock Chase on a Sunday afternoon with great agility.

A flattened top tube gives vertical compliance but lateral stiffness; an all mountain bike that gives the stability of a fat-bike shrunk in the wash with the nimbleness of a trail bike.

Boost 148 and 100, external bolted cable solutions, integrated headsets, through-axle hubs, formed butted smooth-welded tubing gives precise handling.

Transmitter is to ride and enjoy. Easy to ride and maintain. And funner. Much funner.

Vertical compliance and lateral stiffness

The strikingly flattened top tube is the spoonful of black magic we need to make the frameset both rigid and forgiving in all the right places. Stable yet nimble, the geometry has been tweaked to give a spirited ride.

Hand welded 6061-T6 triple butted frameset

Not all tubes are equal, Transmitter uses tube walls of different thicknesses to get material where it is needed and save weight where it isn’t.

Dropper seatpost ready

The Transmitter frame is compatible with a dropper seatpost so even the most sheepish riders can tackle those steep sections head on like a pro.

Tapered head tube

Whoever would choose to be a head tube? You might as well step into the ring with Mike Tyson. This is a critical junction point where force is distributed around the frame and steering precision is won or lost. Transmitter has a wide tapered head tube to house your internal bearings, distributing force more evenly whilst improving steering over broken terrain.

Boost ready

Transmitter is designed around the new Boost standard and corresponding 52 mm chainline for better steering stiffness and increased wheel support.

Chain guide ready

​Transmitter can be fitted with a chain guide. (ISCG 05 compatible).

Wheel compatibility

​Transmitter is designed to run with 650b+ tyres at both ends.

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