EXT Reveal Brand New ERA MTB Fork

EXT are the makers of some very highly regarded MTB rear shocks and are endorsed by Chris Porter of Mojo Rising who are the UK Distributor.

The ERA fork uses our HS3, hybrid air spring. Two positive air chambers work with one, high volume self-activating negative air chamber. Combined with a high-volume damper cartridge this system offers a lot of tuning capability and offers a lot of support in a suspension fork.

About the EXT ERA MTB Fork

HS3 is focused on mid-stroke support around the dynamic sag position while offering amazing sensitivity and bottom-out protection.
The air spring is complemented by an integrated coil spring to create a frictionless sliding movement and a highly responsive fork giving the best grip to the front tyre.

New, patent-pending, crown design that increases stiffness in all load directions and gives more riding precision.

We looked at everything that needed a low friction solution to improve smoothness and sensitivity, that took us to our motorsport heritage:
Developed in the World Rally Championship our new DU bushing material used in the magnesium Lower are sized to defined tolerance for each fork assembly and works in harmony with our dedicated EXT oil and guarantees zero stiction and super low friction properties even when combined with high sideloads.

ERA adopt an innovative Floating internal shaft guide in the damper cartridge uses a Superfinish shaft taking friction to the lowest possible level.
EXT high-volume cartridge uses a high flow piston to generate control for your bike, the ERA is a performance upgrade for your bike and your riding. Like all EXT products, the ERA offers a fully tunable fork with a useable damping range for each rider and riding style.

Our new cartridge also introduces a new Bump valve design (HDRV – High Dynamic Response Valve) with 2 different shim stack for mid and high speed and an Internal Floating Piston guided piston combined with a bespoke thrust bearing to enhance fast response and guidance.

ERA concept wants to be a no-compromise fork on implementing a solution to create performance and better ride control.
