NEW FOR 2019

GRIP2

Next-Generation Sealed Cartridge FIT Damper

GRIP2 is our next-evolution sealed cartridge FIT system, our highest performing gravity-focused damper. The new damper shares its roots with the original GRIP architecture, but has been seriously enhanced with all-new technology: 4-way adjustability, VVC high-speed rebound circuit, high-performance mid-valve, and overall friction-reducing treatments.

GRIP2 Damper
GRIP2 Adjusters

4-WAY ADJUSTABILITY

The revolutionary design of the GRIP2 damper provides independently adjustable high- and low-speed compression and high- and low-speed rebound.

In addition to offering incredible damper control, the adjustments also have a wider compression damping range to increase support without adding harshness.

GRIP2 Variable Valve COntrol

VARIABLE VALVE CONTROL (VVC)

FIT GRIP2 now features high-speed rebound using our novel and patent-pending approach: Variable Valve Control (VVC).

It’s a revolutionary way to adjust the high-speed rebound circuit, effectively changing valve stiffness rather than adding preload.

Unlike normal adjusters that add valve preload, VVC uses a leaf spring to alter valve flex in the high-speed rebound circuit. The adjuster provides the same effect as revalving high-speed rebound but without the need for damper disassembly.

GRIP2 Mid-Valve

MID-VALVE

A sophisticated mid-valve design allows more effective shaping of the compression damping curve, offering confidence-inspiring support that resists brake dive.

Tested and proven on the demanding World Cup Downhill circuit, GRIP2 has been relentlessly tuned to deliver just the right amount of support without harshness, giving it another level of refinement over previous generation dampers.


FRICTION REDUCTION

During the development of GRIP2, engineering uncovered improvements that greatly reduce friction.

Low friction seals help improve small bump compliance and honed, polished, and coated shaft and tube surfaces further eliminate friction for an unmatched ride experience.

Aaron Gwin

"The new GRIP2 damper has been an all around improvement for me. I wanted a fork that could hold up under big compressions, soak up the small chatter, and give me really good front end feel traction wise.

It's no mystery to most that I've always run my suspension pretty stiff to get the hold up and stability that I want. This new damper has a smoother overall feel off the top while adding to that bottom out support deep in the travel which has allowed me to actually back off on my settings now a bit. The new high and low speed rebound adjustment also allows me to control how fast the suspension is reacting through different amounts of travel which leads to a precise set up and all around more controllable ride through the entire range of travel. My hands are thankful!"

Danny Hart

"I'm really happy with the new GRIP2 damper, it has been a really easy change over, I find it gives me much more bump force sensitivity! Gives me much more confidence in the corners because I have no end of grip!"

Danny Hart


TECHNOLOGY

FIT4

A reconfigured shim stack found in all 34 and 36 FIT4 forks provides more sensitivity while maintaining support during aggressive riding.

In its fourth generation, our patented FIT4 closed cartridge system provides three on-the-fly compression damping positions—Open, Medium, and Firm—to adapt to varying trail conditions. Factory Series forks feature an additional 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.

EVOL

Patented Air Transfer Port System

Our EVOL linear spring curve gives forks and shocks plushness off the top, extra mid-stroke support, and more tunable bottom-out progression, allowing riders to tap into the ideal pairing of front and rear-end feel.

FLOAT EVOL Air Spring
EVOL technology from rear shocks is integrated into all FOX forks. EVOL increases negative air spring volume, specifically positioned and sized for optimum small bump sensitivity.

GENUINE
KASHIMA COAT

Buttery smooth

Kashima's distinctive gold color is backed by its high performance attributes—properties that provide an exceptionally smooth feel and extreme durability.
