At a Glance
  • Quick, agile, and stable for trail centres and big mountains.
  • Frame: Sonder Transmitter; hand welded 6061-T6 triple butted; vertically compliant laterally stiff tubing.
  • Drivetrain: SRAM NX Eagle.
  • Forks: Rockshox Revelation RC, 27.5 B, 150mm travel, 46mm offset.
  • Wheelset: LoveMud 650b+ boost.
  • Tyres: WTB Vigilante TCS (front) and Trail Boss TCS (rear).

The signature flattened top tube gives vertical compliance but lateral stiffness - it really is an all mountain bike. That long wheelbase combined with the slack front end, size specific chainstays and a lowered BB give stability and control through the rowdiest of terrain.

Transmitter is designed around Boost 148/110 standards and 650b 2.6/.8 tyres, and optimised for 1x groupsets. The geometry and extra grip from those big tyres means even the most sheepish rider will tackle those steep sections, up and down, like a pro.

Transmitter frames now feature internal cable routing through the downtube, integrated headsets, through-axle hubs, refined dropouts, butted tubes and smooth welds (and 3 shiny new colours).

Transmitter is a bike that just fits in with hard riding. This new version is still the fun trail bike it’s always been, and will still be a perfect partner for multi-day epics or short and fast trail centre blasts, but the changes we’ve made have raised the Transmitter’s limits, so you’ll be able to push the bike harder than ever before!

Why NX?

SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is a solution that is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.

NX Eagle provides the same Eagle performance benefits as the rest of the Eagle family. Slotting in just under the higher priced GX, the main differences are extra weight and the 11-50 range is not as wide as the 10-50 offered with GX, but functionally NX is 12-speed and fully compatible with SRAMs Eagle groupset.

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.

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.

Internal cable routing

Clean lines and tidy cables thanks to fully guided internal routing.

Wheel compatibility

Designed around Boost 148/110 standards and 650b 2.6/.8 tyres

Chain guide ready

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

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.
