Yeti SB165 Complete – Black & Dust (images may not show kit referenced on this page)

SB165 C-Series Suspension Details

Learn more about both the stock SB165 C1 suspension as well as the upgraded FOX Factory option.

This is one of the most popular upgrades, especially on Enduro MTB bikes, as it offers the top of the line FOX dampers with improved compression controls.

Learn more about the Yeti SB165’s 180mm Fork Options

Stock: FOX Performance GRIP
Upgrade: FOX Factory Float 38 GRIP2
BikeCo Upgrade: Add the GRIP2 damper to the Performance to create a Performance Elite fork with improved damping on the black body fork.

Both feature 180 Direct Post Mount and capacity for 230mm rotors, Air Channels and Floating Axles

Factory Suspension includes Kashima Coat, enhanced GRIP2 damper with High and Low Speed Rebound as well as Compression, Internally Elliptical Steerer and Air Bleeders.

Air Spring & Volume Spacers

The FOX 38 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 170mm setup 15% equals 25.5mm of sag. 20% will use 34mm of sag.

Volume Spacers

The 170mm FOX 38 is factory spec’d with 2 volume spacers (bike manufacturers may or may not change this). The 170mm 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.

Stock: Performance GRIP

Rebound – 10 clicks of Low Speed rebound control

or Upgrade to the Factory GRIP2:

GRIP2 High and Low Speed Rebound Control at the base of the damper leg lower.

FOX 38 GRIP2 Rebound Controls

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.

FOX Performance GRIP compression lever

STOCK: Performance GRIP

Three on-the-fly compression damping positions: Open, Medium & Firm

or Upgrade to Factory Suspension

FOX GRIP2 High and Low Speed Compression Controls

FOX GRIP2 Compression Controls

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.

SB165 C1 Rear Shock Options

Stock: FOX DHX2 2 position
Upgrade: FOX Factory DHX2 2 position with SLS spring

Designed around the plush, linear FOX DHX2 coil the SB165 can also run the more progressive FOX X2. Not sure which is for you? Chat with our team about the personality differences on the Yeti SB165 coil versus air shock.

FOX Factory DHX2 Rebound

Like the compression both Low and High-Speed Rebound adjustments are available on the Factory DHX2.

Low-Speed Rebound is adjusted with an allen key near the compression adjustments on the shock head.

FOX Factory DHX2 Rebound Control

High-Speed Rebound is adjusted under the air can. It can be adjusted by hand, although a small allen key inserted in the machined holes may be easier to spin.

As with the compression settings Low and High-Speed Rebound tend to be adjusted within a range.

If you find your adjustments have more than a couple clicks more variance than suggested you might review other settings as well.

FOX Factory DHX2 Rebound Adjustability

High-speed rebound (w/VVC) – 8 clicks
Low-speed rebound – 16 clicks

You can learn more about the base FOX settings here.

FOX Factory DHX2 Compression Controls

The FOX Factory DHX2 rear shock provides riders High and Low Speed compression as well as a 2 position OPEN – FIRM switch.

High & Low-Speed Compression

Adjustments to the High and Low-Speed Compression are found on the shock head.

Low-Speed Compression is adjusted with a 3mm hex while a 6mm adjusts the High-Speed Compression.

FOX Factory DHX2 Compression Control Standard

Low-Speed Compression is typically used with air spring and volume spacing to balance support. With increased Low-Speed Compression the shock will “stand taller” in the travel which helps bikes in fast corners or blasting through the chunk.

High-Speed Compression is often used along with volume spacing to resist high speed shaft movements such as bottom out.

Low and High-Speed Compression are typically set in a similar range. Riders might have a click or two one way or another for fine tuning but if you find yourself with large gaps between the Low and High in order to tune the shock you might review Coil selection and other tuning options which would affect the rebound requirements (check the learn more tab for a video discussing interactions between the various adjustments).

FOX DHX2 Compression Adjustability:

High-Speed Compression: 8 Clicks of Adjustment
Low-Speed Compression: 16 Clicks of Adjustment

DHX2 2 position OPEN FIRM Lever

FOX Factory DHX2 2 Position Switch

The Factory DHX2 2 position switch provides riders a “climb switch” shifting the shock from it’s OPEN circuit to a redesigned independent FIRM circuit.

With this redesign the DHX2’s FIRM position is notably improved for the long climbs for those big descents.

Tuning with Pre-Load & Spring Rate

We’re going to use the FOX DHX2 damper as an example to show you how multiple spring rates will produce similar resistance at a SAG measurement while allowing riders to fine tune the available resistance later in the stroke, often quite notably.

We touched on Spring Rate in the Fitment tab – it’s measured in LBs/IN – how many pounds it takes to move the spring some portion of an inch. Since this is consistent it creates what’s considered a linear spring rate (it will graph in a line) compared to a progressive spring rate of an air shock (which graphs in a “J” shape).

First let’s look at Pre-Load

FOX recommends a minimum of 8 clicks of Pre-Load on a spring and allows for a maximum of 26 clicks (to minimize the chance of coil bind as well as controlling the forces on the spring perches, threads, etc)

So you install the coil, tighten the Pre-Load perch down to contact and then adjust it between 8 and 26 clicks to fine tune your SAG setting, which we’ll say is 30% of the SHOCK TRAVEL. If your coil is sized appropriately – ie more coil travel even with Pre-Load added than available shock travel the coil will be at less than 30% of it’s travel. So remember, the measurement you’re looking for is a difference that equates to 30% of the SHOCK stroke.

example: 55mm SHOCK stroke = 16.5mm of SAG at 30%. so a 210x55mm shock will have an eye to eye endearment of 210-16.5= 193.5mm. If you measure off another component adjust your math as needed (such as spring perch to spring perch, etc depending on accessibility of the shock in your frame).

If with the minimum of 8 clicks your sag setting is LESS THAN 30% sag you’d benefit from a lighter spring rate.

Should 26 clicks find you at MORE THAN 30% sag a firmer spring rate is required.

Spring Rate Cross-Over with Pre-Load Adjustments

Here’s where it gets interesting: Variations in Pre-Load settings create overlap at SAG PSI – meaning you likely have a choice if you want to use the higher spring rate at a lower Pre-Load (which will have a more aggressive spring rate deeper in the travel) or use a lower spring rate at a higher Pre-Load (which will have less aggressive spring rate deeper in the travel).

Here’s an image from our calculator as a quick reference:

BikeCo eMTB and MTB Coil Comparison Example

You can see there is cross over at sag, highlighted in light yellow, between the higher Pre-Load Settings on the 250# coil as well as the lower Pre-Load Settings on the 275# coil.

Looking at the rest of the charts you can see that the higher spring rate coil will provide higher resistance as you pass the 30% SAG measurement. This is kind of like how volume spacers are used to adjust an air spring’s ramp rate.

Want to explore the crossover more? You can use the google sheet FOX Coil Spring Rate calculator here (opens in new tab).

Quick Details on Rising / Falling Rate Suspension

How much of the spring’s power is actually applied into the linkage varies in part tied to the angle of the linkage compared to the spring’s “push”. As this angle is variable with suspension linkage the percentage of the springs actual output to the suspension system will vary.

Coil Spring Angle Correction Factor

Rising / Falling Rate Suspension Illustrated

Above you’ll see a basic illustration showing two rising then falling rate suspension linkages.

What makes this important – a coil spring (or air spring) is only 1 to 1 effective when the spring’s power is pushing at 90 degrees to the linkage arm. On the upper graphic this is shown in the Orange details.

Continuing to reference the upper graphic: at full extension the spring’s effectiveness will be slightly less than the spring’s power rating. As the linkage rotates (clockwise in this case) to the 90 degree angle (shown in orange) it is a Rising Rate suspension.

As the linkage passes the orange 90% point until full compression it is a Falling Rate suspension.

How does this matter or effect you?

Well if you’re read this far I hope you’re learning something and it’s interesting right?

Let’s compare the red details between the upper and lower illustrations now.

In the upper illustration the angle between the spring and linkage is more exaggerated than the lower illustration.

This means at full compression the upper spring is exerting a percentage LESS of it’s rated power compared to the lower red detail which is closer to the 90 degree position, thus it is exerting a HIGHER percentage of the spring’s rated power to the linkage.

If I was considering two spring rates I would likely consider using the HIGHER Spring Rate with less Pre-Load in the upper concept and the LOWER Spring Rate with more Pre-Load in the lower scenario.

Is this somewhat splitting hairs? Of course. But, the data is out there, the components are out there so what harm can the knowledge do? (and, I hope that a disclaimer like this eliminates the snarky comments, or at least some of them!)

Final Thoughts on the Above Calculator

So, the calculator won’t tell me what spring to use? Correct. There are too many individualized factors in each bikes’ design to make that really feasible. This calculator ideally gives you a comparison point if you’ve started with some understanding or data point on your setup.

Your bike dealer or manufacturer should be able to provide you with some basic setup concepts and the calculator would provide a reference to compare options around what they suggest.

Yeti SB165: Comparative Bikes

What else is on your short list when shopping the Yeti SB165?

Well, the SB165 is at the top of the longer travel 27.5″ bikes. As many manufacturers lean out of 27.5″ “big” bikes the SB165 not only performs but outperforms.

This is a bike that’s playful as a 27.5″ bike, has even more capacity in the tank as a mullet with a 29″ front tire – and produces quite the Enduro slayer in the configuration.

For tall riders you may consider a 29″ enduro bike – but if you’re looking for that “compact” wheel to change direction quickly, particularly in the steeps the SB165 is hard to beat.

Chat with our team about the details on which rider and riding style gravitates to the SB165, or a Mullet SB165 or is borderline on the 29″ bikes like the SB160.
