EXT ERA V2.1 PRODUCT DESCRIPTION The ERA V2.1 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 incredible tuning capability and sets a new level for support in a suspension fork. The Era V2.1 introduces features and upgrades that aims to improve the experience, safety and performance of the previous production. At its core the Era V2.1 has the same configuration that made Era famous and appreciated: HS3 system, creak free crown, great mid stroke support, excellent stiffness and performance.The Era fork has a magnesium lower design that makes them lighter and load-optimized and it's made possible by a specific production process called Thixomolding. Other improvements are addressed to increase sensitivity, smoothness, lubrication and safety like the improved end-stroke devices for the HS3 system, the top up bump rubber and titanium plate that reduces noise on ++ chamber or the new DU design that grants better lubrication.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. 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 a defined tolerances 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 side loads. ERA V2.1 adopts 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 V2 .1 is a performance upgrade for your bike and your riding. Like all EXT products, the ERA V2.1 offers a fully tunable fork with a useable damping range for each rider and riding style.

New Era V2.1 features & upgrades Listening to comments and suggestions coming from our riders, we have developed a new kit for the HS3 that’s retrofittable to all V1/V2 models! The system increases Negative Chamber volume, as well + Chamber ,with the task to make the Era even more sensitive over small bump, but also even softer during the main part of the travel to gain more comfort, thanks also to the new spec 53/50. New DU guide bushings All the 2023 fork have now a new Lower DU guide bushing upgrade that are also available to all of the existing forks!The new DU design and material are proven to be a very important improvement for sliding quality, mantaining tolerances and surface low roughness with a very long lasting life span, more than 500.000 cycles, that in” automotive standard it’s considered “life”, with an increasing service maintenance to more than 100 hours.
