    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.

    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.

    Features

    Progressive geometry

    Long reach, low bottom bracket and slack 65° head angle for bucket loads of confidence. 425mm short chainstays for agility and insane acceleration out of turns.

    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 +
