- Fast and aggressive titanium 29er hardtail trail bike frame
- Stiff, durable, and comfortable 3Al 2.5V Aeronautical grade titanium tubing
- 66/74 head and seat angles eat up climbs and descents
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.
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.
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.

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.

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...
