    Accessories

  • Handlebar

    • Sonder Aspect Riser 780mm

    • Sonder Aspect Riser [OEM]

      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

    • Love Mud Abode / 138

    • Love Mud 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.

    Seatpost

    • Sonder Seatpost 31.6mm / 400mm

    • Sonder Seatpost [OEM]

      A seat post that is reliable and offers adjustability to help you find your ultimate riding position.

      Membar is all about adjustability. With a twist of your allen key the micro adjustment rail clamp allows the saddle angle to be fine tuned to your ideal position.

      Your saddle can be fitted with minimal faff thanks to a quick release action that allows the upper rail clamp to be released without removing the retaining bolt. The lower rail clamp is secured to the seat post which means that it will not fall in the mud when you are trying to fit your saddle.

      The flat side has 8 replaceable grip pins, 4 mm long, they provide grip in all conditions. When you are ready to get your power on the cleats are just a half rotation away - no swapping your pedals out.

      Jekyll also comes provided with Sonder 'SH-51 style' cleats.

      • Double-sided adjustable SPD clips

      The Slingshot's wide foot platform provides plenty of support to the foot for more comfortable pedalling over long distances, reducing hot-spots. This additional foot support also gives you greater control of the rear end of the bike on tight turns or technical trail.

      If you're using the Slingshot for mountain biking, the pedal's wide surface gives you a platform to stand on unclipped, ready to bail out if needed, on heart rate-quickening sketchy sections.

      With double-sided SPD clips and a large pedal area, the Slingshot is easy to clip in and out of in a hurry. A clipless system provides greater pedalling efficiency when climbing and more control when descending.

Description

The Signal is 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 the groomed trails at Llandegla and Glentress or take it to big mountains and let loose.

At a glance

  • Shimano Deore M6100 12-speed groupset
  • Rockshox Recon Silver RL fork
  • Sonder Alpha 29" wheelset
  • 4130 Chromoly steel frame

That low BB and long wheelbase gives a planted and stable feel through the corners and when tackling 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" wheels can be paired with 2.2 to 2.6in tyres with clearance for winter conditions.

The Signal Steel rides beautifully – it’s got that distinctive steel feel to take the edge off the biggest hits while keeping stiffness where it counts so you can accelerate out of corners and track accurately through rocks and roots.

Why Deore?

Shimano drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Shimano's new microspline hub means that you can run a 10 tooth cassette for a huge gear range. The new EV shifters and brakes provide loads of adjustment to get the perfect position as well as a rock-solid feel on the bars.

Features

Aggressive trail geometry

​Neil has designed the Signal St 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.

Steel Frame

Nothing feels quite so good as the famously springy and durable Steel. Signal St’s 4130 Chromoly, Hand Welded Steel tubing absorbs shock to soften the ride without any loss to feel or speed.

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.

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 +
