Yeti SB140 29 Frame (shown with Lunch Ride shock) – Turquoise, Sangria, Sage and Raw Carbon available in Small, Medium, Large, X-Large and XX-Large

SB140 29 Lunch Ride vs. SB140 29?

Couple major differences: the Lunch Ride is spec’d with a 160mm fork which gives it the slightly slacker headtube, higher bottom bracket and longer wheel base as well as trail measurements than the standard 150mm travel fork.

The Lunch Ride is spec’d with a more Enduro oriented FOX Factory Float X. Read on to learn more about the Yeti SB140 29 Lunch Ride Frame and SB140 29 Shock Options below.

Yeti SB140 29 T-Series Shock Spec

The Yeti T-Series are spec’d with the FOX Factory Float DPS rear shock.
T-Series Lunch Ride bikes are spec’d with the FOX Factory Float X rear shock.

FOX Factory Float X (Lunch Ride)

The Float X is the next step up in shock disposition for riders looking to push the SB140 into chunkier, faster terrain. The Float X offers better heat capacity and a more aggressive architecture to maintain top level performance longer into fast, burly runs.

Notably the Factory Float X has more sophisticated low speed compression controls which are used to give the bike additional support through the hydraulic system (notably to help the bike ride taller into fast corners or chunky sections). With the increased setup range from the improved compression controls riders have more range to fine tune air volume spacing and therefor ramp rate with the Float X

Debating which rear shock is right for your SB140? Chat with the team at – we will look at your riding style, locale, terrain, ground speed and disposition and help you define where the best value is to get your dream bike performing like you’d expect!

FOX Factory DPS

The DPS FOX rear shocks provide adjustments via PSI, air volume spacing, low speed rebound, 1-2-3 low speed compression in Open mode as well as an Open-Mid-Firm On-The-Fly compression switch.

The FOX Factory DPS is an overall great shock – robust and easy to maintain.

Quick Conclusion: DPS vs Float X

The DPS is lighter, but not by a whole, whole lot. It tends to have a slightly poppy personality than the larger shock option.

The Float X is the more aggressive shock, however, it is also a more adjustable shock overall – so, like the GRIP2 damper on the fork you’re seeing these more aggressive shocks used to facilitate the widest range of tuning as well.

Unlike the fork which can have the damper system swapped out you’ll want to get your rear shock choice right the first time…

Yeti offers a wide range of cross-over kits and can fine tune any build with your dream parts: so if you know what you want let’s get you dialed.

Not sure? Well, you’re in the right place for that. Chat with our team today about your riding style, terrain, aspirations and ground speed and we will help you define which shock will work best for your riding!

Air Spring & Volume Spacers

The Yeti SB140 T-Series spec’s the FOX Factory Float DPS while the SB140 T-Series Lunch Ride spec’s the FOX Factory Float X.

SAG is adjusted by PSI – typically Trail / Enduro riding styles gravitate to 20-25% 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.

Factory Float DPS vs Factory Float X

Both shocks offer low speed rebound adjustment with similar adjustment ranges. Riders shopping the differences between these shocks will often compare the Compression controls and the air spring basics. In theory, the Float X’s rebound circuit is less susceptible to heat saturation issues at high speeds due to the architecture and design.

Rebound Controls

Both the FOX Factory Float DPS and Factory Float X feature a low speed rebound control.

Some Rebound Setup Basics:
Typically higher ground speed means a faster rebound setting.
Heavier riders will use higher rebound settings to better control the increased PSI on the shock’s piston.
Your Rebound Settings will likely change as you progress – this is normal!

One of the advantages working with is a resource to help you stay on top of your settings. We love to stay in contact with our clients and help them fine tune suspension, wheels, tires and cockpits as their riding progresses.

FOX Factory Float X Compression Controls (Lunch Ride)

The Float X provides an on-the-fly switch as well as low speed compression controls.

You can see the compression control positioning on the Float X below.

FOX Float X Compression and 2 position switch

The FOX Factory Float X provides 2 compression controls.

The blue dial above offers 11 clicks of low speed compression control. The low speed compression will help riders fine tune available support into corners or terrain. Paired with volume spacing riders can also adjust bottom out compression and feel for a more progressive, poppy, shock.

Also shown above is the 2 position lever actuated Open & Firm settings (also called a climb switch). This is a quick compression control riders may use on long climbs, however, many riders prefer the Open position on most terrain.

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.

You’ll see the blue lever as well as the black 1-2-3 low speed setting in the image below.

Learn about suspension setup basics on the following tabs. Each tab has a video with the basics of Air Spring / PSI, Volume Spacers, Compression, Rebound (or watch it all in one place with the final tab).

Each tab has a text section with a bit more in-depth look at the typical MTB suspension settings and how they intertwine.

PSI / Spring Rate

MTB suspension must accommodate a wide range of rider weight. To achieve this nearly all forks and rear shocks use an adjustable air spring.

By varying air pressure riders set a desired sag, or percentage of travel that the bike, sits in, under neutral loading.

Modifying this sag percentage will change small bump compliance as well as bottom out characteristics.

Learning how to Pre-Charge your suspension pump will help you make finite adjustments to sag.

Typically 15% sag is for a firm setup and 20% sag is considered plush.

Air Spring Fine Tuning Control(s): Volume Spacers & Compression

Volume Spacers
Air springs ramp rate, sometimes called Spring Rate, is based on how air compresses in the containment cylinder. As the air is compressed the PSI increases according to the decreasing volume of the containment. This is done via non-compressible volume spacers in the air chamber.

Hydraulic damping assists air spring providing support in mid-stroke and bottom out.

Opposing Control: Rebound.
Higher spring rate will drive the suspension back to neutral with more force than a lower spring rate. To keep the bike from skipping across trail rebound damping is utilized.

Volume Tuning

As suspension compresses (travel reduces) a piston moves closer to the end of a sealed container. By decreasing the volume of the container the PSI pushing back on the piston is increased.

By adding or removing non-compressible volume spacers riders modify the air springs ramp rate which directly changes the amount of support and bottom out feel of the fork or shock.

By removing volume spacers a rider increases the available volume in the suspension. The larger volume compresses less per mm of travel resulting in a lower PSI per mm of travel. This creates less support and is utilizes more travel.

Adding volume spacers decreases the available volume. With less air volume the PSI per mm of travel increases providing more support and greater resistance to bottom out.

Opposing Control: Rebound.
Rebound may need to be adjusted for volume tuning depending on how drastic of a PSI change is being tuned in or out of the suspension.

Helping Control: Compression.
Compression provides additional support and bottom out resistance.


Compression controls provide damping to slow suspension travel as a load is applied and the suspension is compressed. (easy one right?)

When riders have found sag and volume spacing preferences compression controls provide minute adjustments to dial in performance. Adding compression provides more support allowing the suspension to ride taller in its travel which is important when dialing in a bikes personality in corners, etc.

With too little compression a bike will sit deep in the travel. This compromises cornering and braking force resistance. Headtube angle, bottom bracket height, front to rear weight bias, etc are modified as a bike goes through its travel. Maintaining control of the use of travel is paramount for good performance.

Since compression hydraulically slows the suspensions use of travel it therefor lowers the air springs PSI. Properly setting compression controls will help ease the load on the rebound system by controlling the air springs push back onto the rebound circuit.

Too much compression will cause a bike to feel harsh and not use appropriate amounts of travel.

Generally, compression settings are fine tuned after sag and volume spacing have riders, in the ballpark.

Low speed compression controls mid-stroke as well as support in cornering and against brake dive.

High speed compression helps with bottom out and high shaft speed inputs.

3 positions switches are a type of compression circuit with Open the most plush, Mid providing some additional support and Firm for climbing. If you climb in firm remember to put it back to plush for the downhill or you are in for a potentially rough ride.


Rebound damping controls a suspensions shaft speed returning to a neutral position. Or, how fast the air spring pushes back as the load changes.

More rebound damping slows the suspension by decreasing the amount of fluid allowed to pass through the hydraulic design.

Less rebound damping allows the suspension to return faster with less hydraulic restriction on the damper.

Rebound setting is based on weight, ground speed, terrain and aggression. Setting the rebound properly means finding the right frequency or feel for your riding.

If your rebound is too fast, or does not have enough clicks of rebound, the bike will tend to skip and suffer poor small bump compliance.

When the rebound is too slow, or you have too many clicks of rebound, the suspension may pack up creating a harsh ride as each bump uses progressively more travel forcing the suspension deeper into the travel, which will have higher spring rates.

Opposing: Air Spring PSI / Spring Rate.

Helping Control: Low & High Speed Rebound.

Some suspension is designed with 2 rebound circuits. The High Speed Rebound circuit is designed to provide additional control resisting increased PSI late in suspension travel.

Typically High Speed Rebound settings are used as the Low Speed Rebound controls edge towards closed. Example: you might not use any clicks of High Speed Rebound until you reach X clicks on the low speed.

Yeti SB140 29: Comparative Bikes

What else is on your short list when shopping the Yeti SB140?

Well obviously you’re looking at the slightly more robust SB140 29 Lunch Ride as well. The Lunch Ride has a fork with 10mm more travel, but more than the travel the more relaxed headtube angle and higher bottom bracket it give it a touch more capacity in the bigger terrain.

Along with the Lunch ride other bikes slightly larger than the SB140 29 include the Ibis Ripmo, Mondraker FOXY and Nukeproof Mega.

If you’re shopping slightly smaller than the SB140 29 the Ibis Ripley, Nukeproof Reactor, Mondraker Raze and Yeti’s SB120 are all a bit more Down-Country and Trail versus the SB140 29 which is an excellent Trail into Enduro chassis.
