        The Signal is fast, it’s for flat out speed.

        It pedals like an XC bike, descends like an enduro bike, and captures the rawness of riding a hardtail on fast, flowy singletrack. Stand up, sprint, and ride it hard on groomed descents at Llandegla and Glentress or take it to the big mountains and get loose.

        At a glance

        • SRAM SX Eagle 12-speed groupset
        • Rockshox Recon Silver RL fork
        • Sonder Nova 29" wheelset
        • Hand-welded titanium frame

        That low BB and long wheelbase gives a planted and stable feel through the corners and on high speed descents, the low stack height leaves you with less of that ‘tall’ 29er feeling – you’ll feel like you’re in the bike, not on the bike.

        Big wheels roll faster. The 29 in wheels can be paired with 2.2 to 2.6ins tyres with clearance for winter conditions.

        The titanium Signal frame is stiff, light and durable. 3Al 2.5V Aeronautical grade titanium tubing softens trail buzz and provides the engaging and lively feel that only Titanium can.

        Why SX Eagle?

        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

        2.6” tyre clearance

        ​Bucketloads of clearance for 2.6” tyres gives you the benefits of higher volume tyres without getting clogged up in UK conditions.

        Aggressive trail geometry

        ​Neil has designed the Signal Ti to suit his aggressive riding style. A low bottom bracket makes it corner like its on rails, a spacious reach gives you room to move around on the bike, and the 66/74 head and seat angles give you the confidence to bomb the descents and while still being able to climb like a mountain goat.

        Guided internal cable routing

        ​Guided internally routed cables for a clean look and silent ride.

        Titanium frame

        Nothing looks quite so good as the famously resilient and durable titanium. Signal Ti’s aeronautical grade titanium tubing absorbs shock to soften the ride without any loss to feel or speed. ​

        Custom available

        ​We can customise any aspect of our Ti bikes. Come to us with what you want and Neil will make it happen.

        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 +
