Description
Purchase both Ferro fork and Arma MX rear shock together and save 20%!
EXT Racing Shox is extremely proud to introduce the brand new FERRO USD 36, an upside-down 36mm stanchions fork which it’s going to complete our E-MX line-up. Hard heat-treated chrome moly steel stanchions (Superfinish surface treatment), 7000 series aluminum construction upper legs and a 205mm travel design with a dedicated triple clamp, make the core of the new 36mm USD fork, 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.
An high-flow 3-way adjustable hydraulic cartridge is installed inside the fork and with an independent High/Low speed compression and Rebound adjustments set a new standard on the fork adjustability, allowing each rider to properly adjust the damping forces according to his riding style and weight. The possibilities to tailor the fork on your preferences have become unlimited!
Available with a flat crown for 19" wheels and drop crown for 21" wheels.
Basic guideline for flat vs drop crown: If you keep stock wheels or go 16/19" or smaller (like 17" street or 16" supermoto wheels) the flat crown is perfect. If you have a Talaria MX3/MX4/R or run a 21" front wheel on your Surron Light Bee, go with the drop crown. The drop crown will fix the Talaria's low front end and will technically work for all wheel sizes.
PRE-INSTALLATION SERVICES (see install video below)
Make installing your new fork a breeze with our pre-install kit and service. When you purchase the Fork Install Kit and the Fork Install Kit Service your fork will arrive already cut to length, starnut installed, and lower steer tube bearing pressed onto your fork and greased. This avoids having to buy expensive special tools or convincing your local MTB shop to do this install for you (most won't). You'll also need a steer tube Spacer Set and if you want to run a 21" with the flat upper crown you'll also need a Zero Stack Upper Headset. You'll be able to install your fork with basic tools that you probably already have. For easy install you will also need a boost spacer to bolt wheel to fork.
If installing on an MX4 or E Ride Pro SS, you will need a 220mm rotor adapter.
