Description

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 SX Eagle?

..Read more

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

SX Eagle provides the same Eagle performance benefits as NX Eagle, but at a lower price point. The main differences stem from the choice of materials and finish options, but functionally SX is fully compatible with SRAMs Eagle groupset.

Features

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).

Geometry and Sizing

Sizing

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. 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
X-Large
Riders of 6ft 2in +

Bike Radar Transmitter Review

A great blend of swaggering, speed-breeding stability sharpened up by instantly reactive, traction-chasing, short stem steering .... Alpkit resets expectations with its new hardtail.

Off Road.cc Review Sonder Transmitter NX Eagle

The Transmitter is a playful, all-mountain rig with some hooligan tendencies. It suits all manners of riding from trail centres to more natural riding to exploring wild bridleways. If you want a ‘one-hardtail-does-it-all’ then the Transmitter will do that in spades.

Singletrack take a first look at the new Transmitter

If you’re a numbers nerd or geometry geek you’ll recognise that while these are significant changes, they aren’t all that extreme and should result in a well rounded riding machine rather than something that only rides in one direction.

What Mountain Bike 5* Transmitter

Genuine game changer .... crazily capable, radical geometry, hardcore hardtail that maximises the control and speed ... outrageously good value ... reset our definition of cost-effective bike performance .... very very nearly saw Sonder take the overall win.
