Sonder Signal Ti XX1 Limited Edition

Limited edition top spec Signal Ti (built to Bike Guru Neil's dream bike spec). A fast and aggressive titanium 29er hardtail trail bike with XX1 Eagle groupset and Rockshox Pike fork


The Signal is for flat out speed. It pedals like an XC, descends like an enduro, and captures the rawness of riding a hardtail on fast, flowy singletrack. Stand up, sprint, and ride it hard on the groomed trails at Llandegla and Glentress or take it to the big mountains and let loose.

That low BB and long wheelbase gives a planted and stable feel through the corners and 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.

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.

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.
