We are dedicated to progress and innovation, and are committed to providing the best possible solutions to the market. Our dedication to progress and innovation will ensure that our customers are always getting the best products available.

Since the growing worldwide success of electric dirt bikes, EXT Racing Shox saw the opportunity to use their decades-long knowledge of suspensions to create a custom solution to achieve the highest performance for their customers. As a result, they are proud to introduce the brand new FERRO USD 36, an upside-down 36mm stanchion fork. This fork is designed with hard heat-treated chromoly steel stanchions and a Superfinish surface treatment, 7000 series aluminium construction upper legs, and a 205mm travel design with dedicated triple clamps. All of these features make the core of the new 36mm USD fork, developed for minimum friction and high stiffness, and will take the E-MX line-up to the next level.
