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.

Air Spring & Volume Spacers
The Yeti SB140 uses a 210 x 55mm shock.
The spec’d Fox Float Factory 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.
SAG is adjusted by PSI – typically Enduro riding styles gravitate to 25-30% sag. This would measure about 17mm for a plush setup.
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 Factory DPX2 Compression Controls
The FOX Factory DPX2 has a 3 position Open, Mid, Firm switch as well as external Low Speed Compression adjustment. The Low Speed Compression adjustment is located in the center of the 3 position switch and is controlled with an allen wrench.
The 3 way switch is great for small adjustments on trail. The Low Speed Compression control allows riders to supplement the air spring support with hydraulic damping. This produces a bike with more support in the mid stroke allowing it to ride taller in the travel. Riding taller in the travel is great for high speed, high g-force cornering as well as attacking steep terrain.

As a result “loose” bikes not only make noise but will also wear prematurely. BikeCo’s expert mechanics go through each chassis ensuring that suspension, bearings, and hardware are setup for maximum performance as well as longevity. Many home builders have a full frame assembly completed by BikeCo mechanics to ensure the best setup, in brief headsets, bottom brackets, suspension, derailleur hangers, etc are gone through piece by piece.
