By creating a Step-Cast option in the FOX 34 designers were able to shave even more weight from the lowers. The FOX Factory 34 Step-Cast is available in both 120 and 100mm travel in 29″ forks as well as a 120mm travel 27.5″ option.

The Factory 34 Step-Cast 100mm fork has an even lighter option in the 32 Step-Cast – however – as more bikes take on wider ranges of terrain the slight weight increase of the 34 Step-Cast is rewarded with increase stiffness.

What is Step-Cast?

It’s a “step” in the casting allowing for a lighter fork lower.

FOX Factory Float 34 Stepcast Lower Detail

You can see in the images (above and below) how the FOX 34 Step-Cast fork lowers are uniquely shaped. The lower travel required for the air shaft and damper allowed the fork lowers to be modified.

These forks still utilize the standard 110mm axle width.

The FOX Factory 34 Step-Cast also features the Kabolt axle to trim even more weight off your bike.

The FOX Factory 34 Step-Cast is available in the 3 position FIT4 damper in a standard (lever at the top of fork) or Remote configuration. The Remote FIT4 offers 3 positions with the FOX remote (sold separately).

Click through the tabs above to learn more about the Factory 34 Step-Cast options, configurations and BikeCo options.

FOX 34 FIT4 Fork

A great option for lighter riders or those looking for a climb switch or on-the-fly adjustment or riders looking for a poppy, lively fork at a bit lower speeds than the GRIP2 damper.

FIT4 Damper

On trail the FIT4 gives riders easy access to a 3 position Open, Medium and Firm setting – great for stiffening the bike’s fork on those long climbs. The FIT4 is robust enough for Enduro duty for lighter riders and provides a great Trail riding feel for a wide range of users.

FOX Factory FIT4 Compression Control

Above is the standard FIT4 3 postion lever.

Below is the FIT4 Remote configuration. The FIT4 Remote requires an remote, sold separately, and routes a shift cable to the 3 position switch.

FOX FIT4 Compression Controls

The inner black knob controls the FOX FIT4’s Low Speed Compression (or Open Mode Adjust) while the larger diameter blue lever is a on-the-fly 3 position Open, Medium, Firm switch.

On-The-Fly – 3 Positions: Open – Medium – Firm
Low-Speed Compression (Open Mode Adjust) – 22 Clicks

Looking for a little more support on your climb? The FIT4 3 position Open, Medium, Firm switch provides a popular pedal platform for those long grinds.

The FIT4 also provides riders tunable support and bottom out resistance with 22 clicks of Low-Speed Compression adjustment. This setting will shift the performance in the 3 position switch’s Open mode. This is popular to give the bike a bit more support in the corners, under hard braking, etc. The 22 clicks of Low-Speed Compression are typically tuned in concert with the fork’s volume spacers.

FOX FIT4 Rebound Controls

The red knob at the bottom of the lower controls the FIT4 Low-Speed Rebound.

Low-Speed Rebound – 10 Clicks

Rebound settings will vary depending on rider size, ground speed and terrain. Ideally rebound is set fast enough to allow the fork to return to neutral before the next obstacle without being a pogo-stick!

*note (per FOX’s site): 34 FLOAT, FLOAT SC, and Rhythm maximum pressure is 120psi/ 8.3 bar

The FOX Float EVOL air spring has been fine tuned over the years to provide riders exceptional performance.

Using volume spacers the FOX Factory 34 Step-Cast fork can modify its progression rate creating either a more linear (less volume spacers, more total air volume) or more progressive (more volume spacers, less total air volume) feel.

FOX 34 Step-Cast Fork Maximum Volume Spacers

Do not use more volume spacers than FOX specifies. Severe damage to the fork and or loss of control will occur.

FOX 34 Step-Cast Maximum Volume Spacers

120mm: 4
100mm: 5

Float 34 Step-Cast: FOX Performance vs. Factory Kashima

Let’s look at some differences from the Factory 34 SC compared to the FOX Performance or a OEM Performance 34 SC.

Float 34 Defining The Differences

FOX Factory

FOX Factory forks feature the Kashima coating as well as the top tier FIT4 damper in standard or Remote configuration.

They’re called Factory or Kashima options. And they’re pretty easy to spot with the dark brown hue.

The FIT4 provides a 3 position OPEN – MEDIUM – FIRM switch for climbing on those long days. The standard FOX 34 Step-Cast features a lever on the top of the fork uppers. The Remote offering uses a shift cable to manipulate the lever (requires remote purchased separately).

FOX Performance ELITE

FOX Performance Elite forks typically feature the top tier damper systems, with all the adjustments of the Factory fork, but have a black ano coating.

FOX Performance

Some forks are available from FOX in a Performance configuration. The FOX Performance forks tend to have a less sophisticated GRIP damper, generally without as many compression controls as the Factory or Performance Elite shocks are spec’d with. The damper body has a black ano coating.

OEM FOX Float 34

You might see take-off shocks in a variety of configurations. Manufacturers can spec differences in the body, dampers, etc so understanding which damper is spec’d on an OEM fork will allow you to compare “apples to apples” so to speak.

FOX Factory 34 SC vs Performance 34 SC

Improved Compression Setup

This is the biggest difference.

The FOX Factory 34 FIT4 offers a 3 position OPEN – MEDIUM – FIRM as well as the 22 clicks of Low-Speed compression adjustment in the OPEN mode.

The Factory forks use the low-speed compression with volume spacing to control support and bottom out.

The Performance 34 GRIP damper has some adjustment to compression, however the circuit is simplified compared the FIT4.

Therefor a Performance fork leans on the volume spacing and PSI to produce support and bottom out characteristics.

This added Compression control is exceptionally notable as your ground speeds increase as well as for larger riders.

Kashima Coating vs Black Ano

Without access to all of FOX’s testing I’m referencing my years of experience riding both FOX coatings as well as our background on custom shock manufacturing and tuning.

The Black Ano coating works well. I ran a Performance Elite fork and shock with the black ano for years without noticing any wear in the coating.

The Kashima coating is slightly more “slippery” – which means less stiction – probably more notable for smaller riders.

When BikeCo has done custom internals or custom branded shocks we work closely with our coating specialists. Many of the additive packages aimed at producing a surface with less surface friction have an additional benefit that they work really well at negating or minimizing heat input on the shaft. This helps minimize performance changes to the shock during a fast run with thousands of shaft inputs. BTW: these additive packs tended to produce a rich, brown color… Just saying…

So in conclusion: Factory forks have notable advantages in overall tuning setup as well as direct benefits for large and small riders on different sides of the spectrum!

Comparing the FOX 34 Step-Cast to other forks

The 34 SC fork is available in 100mm or 120mm travel aimed at the Cross Country, Endurance and into the Down-Country bike lineups.

The 120mm Step-Cast is unique to the FOX 34 while an even more “ultra-light” version of the FOX 32 Step-Cast is available in 100mm travel.

Riders on the fence for a 100mm option should look at their physical size and riding style. The FOX 34 Step-Cast will be slightly stiffer and more robust than the FOX 32 SC.

Riders looking for slightly longer travel options will shop the standard FOX 34 fork.
