What the Fox 36 Factory mountain bike fork is and how it works

The Fox 36 Factory mountain bike fork is a single-crown suspension fork designed for 29-inch and selected 27.5-inch mountain bikes in the aggressive trail and enduro category, using stanchions of 36 mm diameter for added stiffness under hard braking and cornering Fox Factory, 01/10/2025.

It uses a FLOAT air spring, which allows riders to set sag and overall spring rate with a shock pump rather than metal coils. Air pressure can be tuned to rider weight and style, while volume spacers can be added or removed to change how progressive the fork feels deeper in the travel Fox Tech Help, 04/15/2025.

The Factory trim level typically includes Kashima coated upper tubes, which Fox states are intended to reduce friction and improve durability compared with standard anodized tubes by using a hard anodizing process licensed from Miyaki Fox Owner Manual, 03/05/2025.

On the damping side, current versions rely on GRIP or GRIP2 damper cartridges depending on model, with independent adjustments for rebound and compression circuits. Riders can control low-speed compression for support when pumping terrain and high-speed compression to manage sharp impacts Fox GRIP2 Guide, 02/20/2025.

Internally, the fork uses lubricating oil and low-friction seals to control stiction as the stanchions slide in the lower legs. Periodic lower leg service, involving cleaning and fresh oil, is recommended after a set number of riding hours to keep performance consistent and protect bushings and seals Fox Service, 03/01/2025.
