        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 Eagle 90 12-speed groupset
        • RockShox Revelation RC fork
        • Sonder Nova 29" wheelset
        • X-Fusion Manic dropper seatpost

        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 SRAM Eagle 90?

        First, we delivered the dream of the perfect mountain bike shift. Now we’re delivering the dream of ultimate performance for the mechanical mountain bike transmission too. 

        This is Eagle Mechanical Transmission. 

        The world’s first mechanical groupsets to use a Full Mount interface instead of a derailleur hanger. The first to let you shift anywhere, under absolute power, without compromising or compensating. It’s the world’s first mechanical system with incredibly easy “prepare, hang, tighten” installation, no adjustment screws needed. Rebuildable. Reliable. Affordable. Mechanical Transmission is the dream, delivered. 

        Hangerless Interface and Full Mount give the Eagle Transmission derailleur a remarkably strong attachment, clamping around both sides of the frame itself and eliminating the need for a hanger. This super strong connection eliminates variance and improper adjustment across frame designs. It also eliminates hanger failures and allows the derailleur to rotate backward in the case of an impact.

         

        "Please note: The above images are for illustration purposes only and may show alternative parts. The shipped bike will be built with the correct groupset and spec as outlined below.

        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 (157 and 170)cm
        Medium: Riders between 5ft 6in and 5ft 10in (167 and 177cm)
        Large: Riders between 5ft 9in and 6ft 2in (175 and 187cm)
        X-Large: Riders of 6ft 2in + (187cm +)
