Yeti SB140 29 T4 Complete – Turquoise, Raw Carbon, Sage & Sangria (images may not show kit referenced on this page)
Want to learn more about all the available build kits or compare the SB140 vs the SB140 Lunch Ride? We have you covered right here!
Yeti was going to be hardpressed to improve on the game changing SB130 – but the attention to detail dialing in the new SB140 and SB140 Lunch Ride prove the hard work was worth it!
More than an additional 10mm of travel the Yeti SB140 29er has a refined linkage for improved mechanical suspension control. The updates to the linkage and shock location allow lower standover, more room for water bottles while still allowing the downtube to bottom bracket box connector to be raised for better ground clearance.
The 29″ SB140 is available in a larger size run – Small through XX-Large – with size specific geometry including size specific rear triangles with modified chainstay lengths per size!

What’s updated on the SB140 29er?
Is it like a SB130 with a Lunch Ride Shock? Sort of. But better in a lot of ways!
The new Yeti features improved Switch Infinity V2 Assembly on the Turq series builds and frames.
The downtube to bottom bracket interface has been angled up slightly for improved clearance.
SRAM UDH (Universal Derailleur Hanger) allows a stiffer rear end with the new 55mm chainline.
Threaded Bottom Brackets.
The 29″ SB140 Lunch Ride offers a 65 degree headtube angle with a 77 degree effective seat tube angle. The SB140 29er has a slightly steeper headtube angle (due to the 10mm shorter travel fork spec’d) at 65.4 degrees. The effective seat tube angle also is steeper by a half degree compared to the SB140 LR.
Switch Infinity V2
The Turq or T-Series Yeti’s feature the updated Switch Infinity V2 design. This refinement provides the Turq builds and frames with improved trail performance as well as improvements to the serviceability and service intervals.
One of the most notable updates to the Yeti linkage on the SB140 from a usability and user-servicable standpoint is the spec and location of the bearings.
Standard sized cartridge bearings, pressed into the linkage, instead of the front or rear triangle mean that if you need to replace a bearing it’s a far less intimidating process.
With Yeti’s unbeatable frame warranty, being able to freshen bearings or even full linkage without messing with press fits in carbon? Love it.
SB140 Linkage Updates & Improvements
Yeti’s marketing uses a pretty fitting tagline for the SB140: THE MOUNTAIN BIKE. And frankly having owned a SB130 from the launch till mid 2022 I’ll tell you that I believe them.
The advantages of the bike being designed around the 140mm rear travel from the start, compared to the “long shock” Lunch Ride on the SB130, mean that the leverage ratios have been fine tuned from design, through testing into production. This allows the rear shock to be tuned to improve the feel as the bike dips deep into the travel.
The Switch Infinity package provides riders with a lot of trail pop, or free speed when you pump the trail through corners and dips. You know when your friend on the Yeti just kind of disappears in the corners without pedaling? Well – now you know one of the secrets…
The 29″ SB140 also benefits from shock technology’s recent progression. A better understanding of what they need leverage wise to maximize performance from their air chambers. More time to perfect the damper to control the compressoin and rebound circuits. When you’re not changing shocks yearly the experience pays off. You can see that in the evolution of top tier frame designs like the Yeti.
29″ SB140: Yeti Frame Developments
(center) Threaded bottom bracket. Sounds minor? Well, no, not in my book! Threaded bottom brackets are available in a wider range of price (and performance) points. They’re generally easier and less intimidating to change. They tend to creak less although BikeCo’s frame prep service addresses a lot of that anyhow…
(right) SRAM UDH – Universal Derailleur Hanger. Easier to source parts when you have that big moment on a trip and don’t want to miss the next day’s riding. The UDH also allows for a 55mm chainline which produces a stiffer, better tracking rear end.

Looking to mix and match? No problem – dampers and air springs are interchangeable giving riders the ultimate setup options when working with BikeCo.com
Quick Review: SB140 vs SB140 Lunch Ride Fork
The SB140 Lunch Ride features the GRIP2 160mm travel fork while the standard SB140 is spec’d with the FIT4 150mm fork.
The FIT4 may be slightly lighter, but probably not enough for riders to notice. Instead the major differences are in the compression settings as well as the geo modifications from the taller fork.
The Lunch Ride will be slightly more relaxed at speed with a slacker headtube angle, slightly taller bottom bracket and a bit longer wheelbase.
The 150mm SB140 setup will be a bit more quick handling and may track slightly better particularly in steep, technical climbs.
Read more about the differences available in the GRIP2 vs FIT4 in the following tabs.
Air Spring & Volume Spacers
The FOX 36 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.
The 150mm FOX 36 is factory spec’d with 2 volume spacers (bike manufacturers may or may not change this). The 150mm fork can carry a maximum of 7 volume spacers.
The 160mm FOX 36 is factory spec’d with 1 volume spacers (bike manufacturers may or may not change this). The 150mm fork can carry a maximum of 6 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.

GRIP2 vs FIT4 Rebound Controls
Let’s take a quick glance at the differences between the FOX GRIP2, spec’d on the T-Series Lunch Ride, and FIT4, spec’d on the T-Series, Rebound Dampers
FOX GRIP2: High & Low
The GRIP2 damper provides both Low (LSR) and High (HSR) rebound controls.
The addition of the High Speed or HSR control provides increased rebound control to account for the higher PSI produced by aggressive or heavier riders.
Typically riders will adjust LSR, Low Speed Rebound, to suit riding style and taste and refer to FOX’s guide for the appropriate HSR, High Speed Rebound, pairing.
FIT4: On-The-Fly (Compression)
The FIT4 damper provides Low rebound control (LSR).
There are 10 clicks of adjustability on the FOX FIT4 rebound.
Quick Conclusion GRIP2 vs FIT4: Rebound
The GRIP2’s high speed rebound allows slightly more tuning range than a single low speed cartridge.
Whether this is something that the average rider needs, well, more dials is more fun?
The High Speed Rebound is typically moved in direct correlation to the low speed rebound – it would be rare to make “outside the box” adjustments to the high speed rebound setup.
Having ridden both for many years – the truth is the the major difference between the GRIP2 vs FIT4 is in: the Compression circuits – so read on the next tab!
GRIP2 vs FIT4 Compression Settings
The FOX GRIP2, spec’d on the T-Series Lunch Ride, and FIT4, spec’d on the T-Series, Compression Damper Differences
FOX GRIP2: High & Low
The FOX GRIP2 damper provides Low and High speed compression controls to fine tune support.
Compression circuits hydraulically damp (or slow) the fork’s input assisting the air spring in providing appropriate mid-stroke and bottom out feel.
Low Speed Compression helps provide mid-stroke support. This allows a bike to ride taller in the travel in cornering while resisting brake dive, rider weight shift and other slow shaft speed inputs.
High Speed Compression works to fine tune bottom out feel as well as other high shaft speed inputs also known as square edge bumps. Example: if you sprint straight into a curb you’re likely to engage the High Speed Compression even if you’re not using full travel. This is due to the speed of the shaft moving oil to compensate for the hit.
FOX FIT4: On-The-Fly
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)
Quick Conclusion GRIP2 vs FIT4: Compression
The GRIP2 damper will not have the “on-the-fly” switch but gains a High Speed Compression adjustment.
Both dampers have Low Speed Compression controls for fine tuning support into corners, under braking, etc.
The GRIP2’s High Speed Compression is a good tool to control high shaft speed compression as well as assisting with bottom out resistance. A high speed compression control allows riders to find support through the hydraulic system without having to max out the ramp rate through air volume spacers.
With more bits the GRIP2 is a bit heavier damper, however, if you’re looking for maximum adjustability whether you want to run a 150mm or a 160mm fork the GRIP2 is the damper. (in fact you’ll see the GRIP2 spec’d on many down-country and trail endurance bikes at this point as the fork is so adjustable…)
If you’re interested in the GRIP2 in the standard 150mm spec let us know and BikeCo is happy to work with you to dial in your bike.
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 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 “climb” compression switch.
The FOX Factory DPS is an overall great shock – robust and easy to maintain.
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 BikeCo.com – 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!
Quick Conclusion: DPS vs Float X
The DPS is lighter, but not by a whole, whole lot. It tends to have a slightly “poppier” 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 BikeCo.com can fine tune any build with your dream parts: so if you know what you want let’s get you dialed.

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 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.
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.
FOX Factory X Rebound Controls (Lunch Ride)
Below is the rebound adjustment on the FOX Factory Float X
FOX Factory DPS Rebound Controls
Below is the rebound adjustment on the FOX Factory Float DPS
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 BikeCo.com 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.
DPS vs Float X Compression Controls
Along with the air system and heat capacity the compression circuits offer the biggest differences between the DPS and Float X rear shocks.
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.
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.
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.

Yeti SB140 29: Comparative Bikes
What else is on your short list when shopping the Yeti SB140?
You’re looking for something truly “all mountain”. Between geometry and disposition the Yeti SB140 tends to find itself in the conversation with bigger bikes like the SB160. That’s because the SB140 is a fast bike, comfortable in bigger terrain. The SB140 is a bit quicker handling than the SB160 and will be a bit lighter.
Currently the list of bikes that are comparable to the Yeti SB160 would be the Ibis Ripmo with a 170mm fork and the 150mm travel Mondraker FOXY. Both available from BikeCo.com.
If the SB140 is on the bigger side of what you’re shopping you’d compare the SB120, Ripley, Raze and Exie. All of which gravitate in and around that super confident trail bike category.
