      In general riser bars tend to be wider than flat bars and may have slightly more flex to give a more forgiving ride. As you go into descents and your arms drop below your knees the additional height gained on your front end will help you take control of the steep descents.

      That said you can get all bar types in a range of widths and stiffnesses and front end height can be adjusted with spacers like our Sonder Rings, so sometimes you just have to ignore the mumbojumbo and make your call on style and personal preference and there is nothing wrong with that.

    Saddle

    • Sonder Abode Black / 158

    • Sonder Abode [OEM]

      High density foam padding over a plastic base provides comfort and longevity. A v-shaped split at the rear of the saddle allows flex as you are riding, increasing shock absorbancy and reducing pressure on the spot between your sit bones.

      Scooped up at the back with a slight rise towards the nose the longitudinal profile provides a cupped, craddled seating position, a timeless, proven design for distance on and off the road or climbing in the mountains.

      Stainless steel rails give 50 mm of forward and back adjustment to help you find your sweet spot.

      All our Sonder bikes come with Abode fitted as standard.

    • X-Fusion Manic Drop Seatpost and Lever

      The X-Fusion Manic Dropper has been designed to work well across cross-country, trail, all mountain and enduro riding.

      It works on a simple design. Inside you’ll find a closed cartridge that is both sealed and designed to be easily removable from the rest of the post. Simple construction aside, the action of this post feels super-smooth and silky.

Description

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.

Every Signal Ti Pinion is built to order. This means the geometry, the tube lengths, the specification, everything is chosen exactly for you, your partner and the journeys you'll take together.

It takes six months from the first conversations we have with you to getting your Signal Ti Pinion for your first ride. In this time we'll talk exactly about what you need and where you're going so that we can design and build your perfect tandem. It's actually a joyful six months, filled with the involvement of having a bike built especially for you, knowing the care and complete obsession over the detail that's going into it. Neil and our team of designers and builders are in touch every step of the way. It's a truly special experience.

At a glance

  • Pinion C1.12 gearbox
  • Cane Creek Helm MK2 Air fork
  • Sonder Alpha 29" wheelset
  • Rockshox Reverb 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 Pinion?

The pinion version of the Signal puts all the moving parts of the gear system out of harm’s way and gives an almost silent, well-balanced ride.

It’s a low maintenance dream - you can cover 10,000km before you need to think about an oil change. The range of gears is just enormous (600%) and because of the way the gearbox works you can dump all of them in one go if you get caught out at the bottom of a brutal climb. It’s an amazing experience.

All the weight of the gears are low and central with a pinion gearbox so handling of the Signal Pinion is beautifully balanced and assured.

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 +

Neil Cottam Reviews the Sonder Signal Ti

It is possibly the best all-round trail hardtail that I've ever ridden, I wanted to be out riding on it all the time - that is the mark of a good mountain bike.

Singletrack Review the Sonder Signal Ti

You know that rock garden that you’ll happily hop into on your full bounce bike? Well, the Sonder will do it too, only you’ll probably lift the front end higher, get airborne further and completely clear the whole lot...
