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

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. 

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