Yeti SB140 Mullet Options
Like the Yeti SB165 the SB140 is designed as a 27.5″ bike. However, it’s geometry and personality make it a great candidate for a 29″ front wheel or mullet build.
Why add a 29″ wheel? Improved roll over, cornering traction and braking.
Why not go to a true 29″ with the bigger wheel as well? The smaller 27.5″ wheel is quicker around corners and the smaller diameter means riders can get lower on the bike in the steeps or jumps.
De-Traveled Mullet Setup
With the increase of the wheel radius a Mullet 29″ will have a shorter fork travel than it’s 27.5″ counterpart. We’ve actually gone a bit further with the concept and have been working with 29″ forks that mimic the axle to crown measurement as close as possible to the designed 27.5″. This gives the bike a turning and climbing personality close to the Yeti design. Poppy, Confident, Fun. Giving up the extra travel on the fork is negated by the additional “false travel” or increased feel from the larger wheel.
One of the most notable improvements when going to a 29″ front wheel from a 27.5″ option is the extra traction when braking. The larger fore to aft contact patch means the the bike is working harder without as much input. This is great in situations where you may have to trail brake into a corner.

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 into” 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.
Compression.
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 spring’s 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
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 bike’s 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 suspension’s use of travel it therefor lowers the air spring’s PSI. Properly setting compression controls will help ease the load on the rebound system by controlling the air spring’s 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’re in for a potentially rough ride.
Rebound
Rebound damping controls a suspension’s 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 doesn’t 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.

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. On the stock 160mm setup 15% equals 24mm or about 1 inch of sag. 20% will use 32mm or about 1.3″ of sag.
Volume Spacers
The 160mm FOX 36 is factory spec’d with 1 volume spacers (bike manufacturers may or may not change this). The 160mm 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.
FOX 36 GRIP Rebound Controls
The GRIP damper provides 10 clicks of low speed rebound located at the red knob on the bottom of the fork lowers.
FOX GRIP Compression Controls
The Performance GRIP offers a 3 position on-the-fly adjuster for Open, Mid and Firm.
FOX also offers micro-adjust detents between the settings.
Learn more about the Yeti SB140’s FOX Float Performance DPX2
Air Spring & Volume Spacers
The Yeti SB140 uses a 210 x 55mm shock.
The spec’d Fox Float DPX2 is the most popular based on its wide variety of terrain capacity. Enough shock for the bigger stuff while poppy on your trail adventures.
Some riders will upgrade to the more robust Float X2 with high and low speed adjustments for both rebound and compression.
SAG is adjusted by PSI – typically Enduro riding styles gravitate to 25-30% sag. This would measure about 17mm for a plush setup.
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 DPX2 Rebound Control
The FOX Factory DPX2 provides a low speed rebound control.
As rider ground speeds increase they will allow the rebound to “speed up”.
The higher PSI the more rebound control a rider will need to control the more forceful air spring.
Rebound should be set to allow the suspension to return to neutral before the next terrain feature without being so fast as to “skip” across the trail.
FOX Performance DPX2 Compression Controls
The FOX Performance DPX2 has a 3 position Open, Mid, Firm switch.
The 3 way switch is great for small adjustments on trail.
