The Essential is the bike that started ARC8. A bike designed for best fun out on the trails, but as it turned out also light and efficient enough for success in XC racing. Now in its second generation, it has grown more character, expanding its versatility even further. Still at XC weight, it now sports a 64° head angle for a lot of control on steep, technical descents, while the low BB and short chainstays bring the party to the woods.
Staying true to its original spirit, it turns trails into your playground, no matter where you are. Big days in the mountains or just having fun in your local woods, the Essential is your best companion.

Frequently asked questions

It covers well what people call trail or all mountain. But it doesn't mind an occasional XC or enduro race. 

The Essential was developed and tested for a maximum system weight (rider, bike, riding gear) of 110 kg. 

We recommend cleaning the rails after every ride and removing any dust or dirt from the wipers. In adverse conditions (mud or fine dust) or after a few days on the trail, it's helpful to apply a drop of suspension fork oil in front of and behind the Slider on the rails. Then compress the bike to work in the oil. Wipe off any remaining dirt once more. We've had good experience with R.S.P HyperWiper, for example. After that, your bike is ready for the next ride.

All shocks we specify for our mountain bikes are tuned in close collaboration with the respective suspension manufacturer and tailored to the bike’s kinematics. Due to our custom suspension layout, standard shock tunes often don’t work optimally and may limit the bike’s performance. For example, the compression tune might be too firm, or the rebound too slow. That’s why we strongly recommend using a shock we’ve specified – to ensure you get the most out of your bike and enjoy every second on the trail.

Unfortunately, the Essential is not approved for use with coil shocks.

In general you can mount any 4-piston brake, if it is a flatmount brake. As far as we know, there is only one supplier offering a 4-piston fatmount version. Unfortunately at this point there is no adapter solution which solves this. 

Yes, the Essential is UDH compatible.

For the Essential, you need a T-Type chain with 116 links. Setup is done on the 7th cog (21 teeth). Setup key position is A. This applies to 32 and 34T chainrings. More info: https://axs.sram.com/guides/fullmount/chain/calculator

The Essentialis designed to be used with short stems. We recommend stems that are 35 to 55 mm long. 

The Essential uses a BSA threaded bottom bracket. For SRAM: DUB 73 WIDE; for Shimano: MT800 (BSA) with 3 × 2.5 mm spacers
