The Extra comes alive when the terrain gets challenging. Everything on this bike is designed to boost your confidence, starting from a geometry akin to a downhill bike, over big wheels, to frame stiffness. A long reach, 64° head angle, and low BB mean all business in the front. There is still some party in the back though, with short chainstays keeping the bike alive and giving it some pop when taking off on small features.
It is easy to get to the top as well, thanks to a steep seat angle, efficient suspension, and low weight.
With our frameset, you can build it into the bike you want. Put on some sturdy tires, coil springs and a 180 mm fork, and you can go absolutely mental on this bikes. Or put on a 160 mm fork, air sprung fork and shock, and reasonable tires, and you are all set for epic days in big mountains.
Longer, slacker, lower, with short chainstays. We are not going to repeat how that concept works, because you probably already heard it a thousand times since we designed the first 29er using it before people even knew what a long travel 29er is (it earned the "best geometry in the business" comment from Dirt Magazine back then). Just let us tell you, it still works. Something almost the entire industry gets wrong about seat angle is that the seat angle matters at the height of your saddle, not of your headset. Therefore, we measure our seat angle to an average seat height of 750 mm. You don't get that "theoretically ok, but in reality much too slack" seat angle that so many 29ers suffer from.
Creak free, easy maintenance, not fit issues - all our frames come with threaded BBs.
All cables go through the headset into the frame. This does not only offer an exceptionally clean look, it also means the cables interfere less with your steering.
The swingarm goes into the seat tube rather than around it, creating a very stiff connection. We are using Enduro Max bearings, specifically designed for MTB full suspension frames.
We do not design our frame, and then give it to a factory to make it happen in carbon. Our frames are designed with the manufacturing process in mind from the start. Only like that we can ensure a carbon structure that can be produced with consistent high quality. While the focus in the development of carbon frames very often just lies on stiffness and weight, we also put a lot of effort into minimizing the chance of manufacturing flaws like voids, wrinkles or low compaction areas. This is absolutely critical to make carbon products not only light and stiff, but also durable.
While lucky enough we did not have to go through that episode of ever shrinking "plus" tires, it left us with the great outcome that there is a wide choice of 2.6" tires. Many tests show it to be the fastest option, so making the Extra compatible to it was a no-brainer.
When trying to combine 29 x 2.6 tires with good chainring clearance and short chainstays, there is just not enough room for the chainstays. Luckily now there are most cranks available with an even further outboard, 56 mm chainline without affecting Q factor. To get the cassette aligned, we keep using 148 mm hubs, but offset it 4 mm to the right, which provides multiple benefits:
The kinematics were designed with some progression to suit air and coil spring shocks. Leverage is highest at sag point for best sensitivity and a falling rate provides resistance against bottom-outs.
