The ARC8 Extra ST is an Extra with the ST Link in the rear suspension. Effectively you get 2 Bikes in 1. Add a Standard Link and you get 160mm Rear Wheel Travel
We built the Extra ST inspired by our local trails where it’s right at home. It’s riding on these trails where behind every corner a root is your potential take off, a dip waits to be manualled or a rut becomes your next berm. The Extra ST is an enduro bike condensed into a smaller package which unleashes the most fun out of those trails.
Where a trail becomes too dull on a bigger bike, it becomes a playground full of opportunities on this bike. The shortened travel injects a healthy dose of playfulness and efficiency. There certainly is a danger of going too wild on this bike. But in those moments, the Enduro-worthy geometry will have your back and guide you out of trouble.
You are wondering what category of bike the Extra ST belongs to? We don’t know either. But be assured, it is more fun than any of them.
BSA BB
Creak free, easy maintenance, not fit issues - all our frames come with threaded BBs.
INTERNAL CABLES
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.
REVERSED MAIN PIVOT
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.
2.6" TYRE CLEARANCE
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.
OFFSET REAR AXLE
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:
- More even spoke tension
- Less exposed brake rotor
- Weight savings over a 157 mm hub
- You can keep your 148 mm wheels. Redishing them by 4 mm can be done keeping the same spoke lengths (theoretical difference is less than half a millimeter.
Designed for Carbon
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.
