Yeti SB120 T-Series Suspension Details

Learn more about the stock SB120 Turq FOX Factory suspension as well as available upgrades.

Yeti SB120 T4 Fork

White the Yeti SB120 T1 and T3 are spec’d with a 130mm travel FOX Factory 34 GRIP2 the SB120 T4 is spec’d with the FOX Factory FIT4.

The FIT4 provides a 3 position “on-the-fly” adjustment for Open, Mid & Firm as well as 22 clicks of low speed compression.

Of course, riders can also upgrade to the GRIP2 damper as well!

The GRIP2 provides riders both high and low speed controls for rebound and compression.

Air Spring & Volume Spacers

The FOX 34 provides riders a range of setup options using air spring as well as volume spacers.

Suggested sag is 15% for a firm feel and 20% for a plush fork. On the stock 130mm setup 15% equals 20mm of sag. 20% will use 26mm of sag.

Volume Spacers

The 130mm FOX 34 is factory spec’d with 2 volume spacers (bike manufacturers may or may not change this). The 130mm fork can carry a maximum of 5 volume spacers.

Do not install more volume spacers than the FOX advises. Installing more than the maximum volume spacers will result in  product damage and potential for injuries, etc.

FOX 34 FIT4 Rebound Control

The FIT4 damper provides Low rebound control (LSR).

There are 10 clicks of adjustability on the FOX FIT4 rebound.

With the updated fork architecture riders can also utilize the GRIP2 damper in the FOX 34. Riders who prefer the option of High and Low Speed Rebound should investigate the GRIP2 (more on this below!)

FOX FIT4 Compression Controls

FOX FIT4 Compression Controls

The FOX FIT4 has a 3 position “on-the-fly” switch with Open, Medium and Firm compression settings. (shown in blue on the image above)

The FIT4 also offers riders 22 clicks of low speed compression adjustment in the OPEN mode. (the black dial in the center of the damper)

GRIP2 Upgrade: riders looking at the GRIP2 damper will not have the “on-the-fly” switch but gain a Low and High Speed Compression adjustment.

Yeti SB120 T-Series Shock Spec

The Yeti T Series (or Turq Series) SB120 T1, T3 and T4 builds are spec’d with the FOX Factory DPS.

Air Spring & Volume Spacers

The spec’d Fox Float Factory DPS is the most technical single can shock on the market

SAG is adjusted by PSI – typically Down-Country / XC riding styles gravitate to 25% sag.

Volume Spacers

Volume spacing provides fine tuning options to support the air spring.

By adding volume spacers, thus reducing the volume, you increase the air spring’s ramp rate for improved bottom out support and pop.

Conversely removing volume spacers produces a more linear feel as the air has more volume during shock compression per mm of travel.

Do not install more volume spacers than the FOX advises. Installing more than the maximum volume spacers will result in  product damage and potential for injuries, etc.

FOX Factory DPS Rebound Control

FOX FLOAT DPS Rebound Controls

Low Speed Rebound is controlled on the red knob shown above.

As your ground speed increases you will speed up your rebound setting to allow the fork to reset for the next obstacle more quickly.

Heavier riders tend to require more rebound control to make up for the higher piston PSI to keep the bike settled.

Not 100% sure on suspension? No problem. When you buy a bike from we are here to help you dial it in and then we work with our clients to fine tune and adjust the setup as their riding changes and ground speeds increase.

Fox Factory DPS Compression Open Adjust and 3 position switch

FOX Factory DPS Compression Controls

The FOX Factory DPS provides 2 compression controls.

First is the lever actuated Open, Medium & Firm settings (also called a climb switch). This is shown in blue in the image above.

The Factory DPS also provides a 3 position Open Mode adjuster. It is mounted between the rebound and the lever. 1 is open, 2 is a bit more support and 3 is even more support – all in the OPEN mode of the lever.

BikeCo Exclusive: Pro Tune Suspension

There are a lot of reasons to shop at The Bike Company ( Some are: Unmatched attention to detail. Incredible after sales setup follow up. Pro Tune Suspension.

Our team works with the FOX fork and shock lineup to take the already great FOX suspension to the next level. Working with our team of suspension tuners we will narrow the FOX performance window based on your size, riding style, terrain, ground speeds, aggression, goals and chassis.

What’s it mean to narrow the performance window? Well, each click is more precise. The fluid is hand picked for you. The bleed is more precise.

On trail your suspension will be more plush while maintaining the support and progression you need to really attack the trail.

For racers our tuned suspension subtracts seconds from your run. For pleasure riders it improves the traction and feel allowing you to progress quicker in your riding.

Yeti SB120: Comparative Bikes

What else is on your short list when shopping the Yeti SB120?

You’re looking for something fast. Flickable. And confident. The SB120 would compare with the Nukeproof Reactor and Ibis Ripley in many ways. Going slightly larger you might shop the bigger Yeti SB140 or Mondraker Raze as well. For a more XC oriented bike the Ibis Exie and Mondraker Podium are class leaders.

The SB120 is a very confident Down-Country and Trail bike. It might be a little bigger than a pure XC rig, but that tends to make it a fun bike in a wider range of trails.
