EXT Ferro EMX Fork

The #1 Ultimate Fork for Small eMoto!

EXT Racing Shox FERRO USD 36 is an upside-down 36mm hard heat-treated chrome moly steel stanchions with Superfinish surface treatment, 7000 series aluminum construction upper legs, and a 205mm travel design with a dedicated triple clamp, developed for minimum friction and high stiffness.

The FERRO USD 36 fork uses the HS3 technology, the unique hybrid air spring system, already been famous with the appreciated MTB fork ERA V2. Two separate positive air chambers work with one high-volume self-equalizing negative air chamber; HS3 is focused on mid-stroke support around the dynamic sag position while offering amazing sensitivity and bottom-out protection.

A high-flow 3-way adjustable hydraulic cartridge is installed inside the fork and, with independent High/Low speed compression and Rebound adjustments, sets a new standard for fork adjustability, allowing each rider to properly adjust the damping forces according to his riding style and weight. The possibilities to tailor the fork to your preferences have become unlimited!
