YETI SB140/LR OWNER’S MANUAL

Overview
The YETI SB140/LR is a high-performance mountain bike designed to deliver an exceptional riding experience. The bike is equipped with patented Switch Infinity technology, a high modulus carbon fiber main frame and swingarm, and other advanced features that provide efficient pedaling performance and smooth support on rough terrain.

Frame Features

• Switch Infinity Technology Patented Suspension System: The SB140 delivers 140mm of rear travel with our patented Switch Infinity technology. Efficient pedaling performance while still smooth and supportive when the going gets rough.
• High Modulus Carbon Fiber Main Frame and Swing Arm: High modulus carbon is hand laid to create our Turq Series frames. That same stiffness and efficiency can also be found in our carbon series frame sets.
• Floating Collet Axle System on Pivots Increases Bearing Life: Floating collated pivot axles help create a perfectly aligned connection between the front and rear triangles of the frame. Allowing the enduro max sealed bearings to keep things moving freely at the pivots.
• Integrated ISCG-05 Mounts: 3-bolt ISCG-05 chain guide mounts are there for you in case you need extra drivetrain security for rowdy sections.
• Rattle-Free Cable Port Assembly Secures Cables and Hoses to Provide a Silent Ride: The SB140 is designed with clamping cable ports to insure a quite ride, reduced cable movement and clean aesthetic. The ports are configurable so you can chose cable or wireless components without leaving behind open housing ports.
• Internally Molded Cable Tubes for Hassle-Free Routing and a Quiet Bike: Gone are the days of fishing your cables through your downtube hoping they pop out the other side. The SB140’s internally molded cable tubes allow you to put the cable in one port and have it come out right where you want it.

DROPPER POST INSERTION GUIDE

Droppers are an essential tool for the modern mountain bike but proper clearance checks are required before heading out for your first ride.
The key checks are as follows:
Ensure your dropper is short enough to fit into the seat tube without interfering with the frames structure but you are still able to achieve your desired BB-Saddle measurement. See the max insertion depth chart to confirm this distance for wired and wireless posts.
There are some scenarios where you can fit a longer dropper in your frame but when you drop your dropper the saddle or battery for AXS posts could interfere with your tire during a suspension compression. See the Min BB-Saddle at full drop to confirm this distance.
Always perform a final check to ensure your post is installed to at least the minimum insertion line. Also, compress the dropper and suspension, let the air out of your shock, to ensure there is no tire interference to the saddle or AXS battery at full bottom out.
We strive to spec out dropper lengths to provide the maximum drop for the highest percentage of our riders. There is a wide range of saddle heights for every frame size. There is a possibility saddle height could fall outside of this range. A small percentage
of customers might find they require a shorter or longer post given their saddle height.
Please ensure you check the minimum dimensions in the below tables before going for your first ride. Failure to do so could result in tire to saddle rub or tire to battery contact for AXS posts.
Please confirm both of these measurements, they are both required to ensure proper dropper fitment.
If you have any questions, please contact Yeti or your local bike shop.

*These measurements are only for cabled droppers. Please make sure if you have a wireless post you confirm that there is not any interference of the tire hitting the battery when the post is fully dropped and the suspension is fully compressed.
**If you go lower then listed minimum you run the risk of tire to saddle interference.

FREQUENTLY ASKED QUESTIONS (1 OF 2)

WHAT IS THE DIFFERENCE BETWEEN THE TURQ AND CARBON SERIES SB140?
TURQ Series bikes are manufactured with the highest quality and best- performing carbon fiber available and offer the perfect balance of stiffness, durability, and compliance. The result is a bike that feels smooth, solid and aggressive. Carbon series bikes use a modified carbon fiber layup of our TURQ Series bikes. By using different materials and tweaking the fiber layup, we are able to make a more aggressively priced carbon high-performance mountain bike while maintaining the strength and stiffness of its higher end sibling. The carbon series SB140 weighs a bit more, about 220g for a frame.

WHAT IS SWITCH INFINITY TECHNOLOGY AND HOW DOES IT WORK?
Switch Infinity utilizes a patented translating pivot that automatically switches direction as the bike moves through its travel. This provides excellent anti-squat characteristics for superior pedaling performance and ideal suspension characteristics as it gets deeper into the travel. Inside are a pair of greased bushings that slide up and down on two Kashima coated rails – it’s not an extra shock that needs to be filled with air. Just keep it greased and wiped clean per our maintenance recommendations below.

DOES THE SWITCH INFINITY SYSTEM REQUIRE MAINTENANCE?
The fully sealed Switch Infinity mechanism has external grease ports to lube the bushings and seals. Yeti and development partner Fox Racing Shox recommend a lubrication interval of 40 hrs of riding. It is important not to over lube the system and adhere to the recommended interval.
It also doesn’t hurt to wipe off any excess dust and dirt that may accumulate throughout the week. Any maintenance supplies you need can be found on our webstore or at your local dealer.

CAN I REPLACE OR MODIFY ANY YETI FRAME PARTS ON MY SB140?
All replacement frame parts for your SB140 can be found through your local dealer or on our webstore. Only genuine Yeti parts should be used when replacing any parts on your frame. We know there are a lot of aftermarket products out there that seem legit but we do not have the ability to qualify and ensure all of these products are safe to use on our frames. If it is found that any frame part has been modified or replaced all warranties will be voided and all liability will be assumed by the customer.

CAN I CHANGE OR UPGRADE THE SPEC COMPONENTS ON MY SB140?
There are many options in aftermarket parts to upgrade or personalize your bike. Some parts are standardized, especially from the big brands like Fox, Shimano, SRAM etc. You should always confirm with a professional mechanic that your parts are the correct standard and correctly and securely mount to your bike without any interference or play. Pay special attention to all the bikes standards and check the fit before use

CAN I USE AN ANGLESET ON THE SB140?
The SB140 was designed with an integrated headset which has the headset cups molded into the frame so you can easily drop the bearings into the cups. There are some aftermarket angle-sets available for this style headset however the frame was not tested for the use of these and therefore should not be used. Yeti’s warranty will be voided if it is found an angle set was installed on the frame and all liability will be assumed by the customer. See “What travel fork is the SB140 designed to use” for more information.

WHAT TRAVEL FORK IS THE SB140 DESIGNED TO USE?
The SB140 is designed to run a 150mm or 160mm travel fork. We tested this frame to 20mm over the spec fork. So if you’re feeling the need to beef up the fork you can run up to a 180mm fork no problem. Bottom line – max axle to crown measurement of 595mm. Increasing your fork travel will slacken the head angle and seat tube angle and raise the bottom bracket. Running a shorter fork is fine too if that suits you. Shortening the fork will steepen the head angle and seat tube angle and lower the bottom bracket For more geometry information, check out the geometry section.

HOW BIG OF A TIRE CAN I FIT ON THE SB140?
The short answer is the SB140 can accept up to a 2.6” tire. There is great tire clearance on the SB140 but tire sizes vary widely by manufacturers, so it is hard to give a number that works for all brands.

CAN I FIT A WATER BOTTLE INSIDE THE FRONT TRIANGLE?
Yes, we designed the SB140 to accommodate a standard sized water bottle inside the front triangle of sizes L-XXL with a piggy-back shock. Size SM and MD frames will fit a standard 21oz water bottle with a piggy-back shock. We recommend using a side-entry cage for easiest access.

WHAT CRANKS AND BOTTOM BRACKET CAN I USE ON THE SB140?
The SB140 bottom-bracket standard is BSA 73mm and only wide “q” factor cranks are compatible. It is readily compatible with Shimano, SRAM, and RaceFace cranks, but a fit
check is required for other brands.

WHAT REAR WHEEL AXLE FITS ON MY SB140?
The SB140 is designed to work exclusively with SRAM’s Universal Derailleur Hanger at 12x148mm spacing. This axle has a thread pitch 12×1.0 and a length of 172mm. Note that this axle is only compatible with frames specifically designed with the Universal Derailleur Hanger.

WHAT TYPE OF HEADSET DOES THE SB140 USE?
The SB140 uses an Integrated 41mm/52mm tapered headset. This system allows for the headset bearings to be contained inside the head tube for an overall lower ride height, more simplified installation, and increased stiffness.

HOW BIG OF A ROTOR WILL FIT ON THE FRAME?
The SB140 has a direct mount rear brake tab and can run a 180mm rotor without the need for
a brake adaptor. With the use of a brake adaptor the frame can accept up to a 203mm rotor.

CAN I RUN A STEALTH SEATPOST DROPPER ON THE SB140?
Yes. The SB140 has routing options for stealth only.

WHAT CHAINLINE WAS THE SB140 DESIGNED AROUND?
The SB140 was designed around a 55mm Boost chainline. Depending on the crank and chain ring configuration you can run other chainlines but you will have to do a clearance check first.

WHAT IS THE MAX SIZE SINGLE-CHAINRING THAT FITS ON THE SB140?
Without getting too technical, the max chainring size depends on the crank chainline and the chainring shape.

• Shimano / SRAM 55mm chainline Boost cranks: 34t round / 32t oval
• Minimum Chainring Size: 28t round / 30t oval

Confused? Ask your local dealer or call us 303.278.6909.

DOES THE SB140 HAVE ISCG MOUNTS?
Yes. The SB140 has integrated ISCG ’05 mounts. It is designed to work best with low-profile modern guides; depending on the brand, some older models with larger upper guides may not fit. We always recommend performing a fit-check with a specific chainguide to confirm compatibility.

WHAT TYPE OF SHOCK DOES THE SB140 USE?
The SB140 uses a 210 x 55mm shock. Depending on the shock model, it can be locked out but we recommend running it fully open for the best compliance and traction.

WHAT TYPE OF SHOCK HARDWARE DOES THE SB140 USE?
The SB140 uses M8x36mm hardware on the air can side and a custom Yeti reducer on the shaft side. If you swap between shocks, the reducer can be found here, https://yeticycles.com/gear/detail/shock-eyelet-spacer

CAN I PUT A COIL SHOCK ON MY SB140?
Yes, the SB140 is designed to be compatible with both air and coil-sprung shocks.

WHAT PERCENTAGE SAG DO YOU RECOMMEND FOR THE SB140?
We would advise starting with 30% sag, or 16.5mm of shock stroke for optimal pedaling efficiency and terrain compliance. Be sure to set your sag at your normal riding weight, gear included. Feel free to venture slightly above or below 30% to suit your personal preference.
Visit our shock set up page to help set up your suspension, https://shocksetup.yeticycles.com/calculator

WHAT SIZE SEAT POST DOES THE SB140 USE?
The SB140 uses a 31.6mm seat post.

WHAT SIZE SEAT COLLAR DOES THE SB140 USE?
The SB140 uses a 36.4mm seat collar.

WHAT IS THE WARRANTY ON MY SB140?
The SB140 has a LIFETIME manufacturer’s warranty.

WHAT IS THE LONGEST TRAVEL DROPPER POST I CAN RUN ON THE SB160?
This is mostly defined by your inseam. You can run any travel as long as you are above the minimum insert mark and you are not so low your tire rubs on your saddle or your dropper bottoms out in the frame. Your local Yeti dealer can help you sort this out. We run 150mm drop on SM frames, 175mm drop on MD frames and a 200mm drop on LG-XXL.

CAN I CONVERT THIS BIKE INTO A “MULLET” BIKE AND PUT A 27.5” WHEEL ON REAR OF THE SB140?
It is possible, but we would not suggest it as it would lower your BB too much and slacken your head tube angle and seat tube angle. But hey, if those changes suit your ride style then go for it.
