DROPPER POST INSERTION GUIDE

SB120 | OWNER’S MANUAL

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.

FREQUENTLY ASKED QUESTIONS (1 OF 2)

SB120 | OWNER’S MANUAL

WHAT IS THE DIFFERENCE BETWEEN THE TURQ AND CARBON SERIES SB120? 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 SB120 weighs a bit more, about 200g 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.
For detailed maintenance information, please visit https://www.ridefox.com/fox17/help.php?m=bike&id=465
CAN I REPLACE OR MODIFY ANY YETI FRAME PARTS ON MY SB120? All replacement frame parts for your SB120 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 SB120? 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 SB120? The SB120 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 anglesets 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 angleset was installed on the frame and all liability will be assumed by the customer. See “What travel fork is the SB120 designed to use” for more information.
WHAT TRAVEL FORK IS THE SB120 DESIGNED TO USE? The SB120 is designed to run a 130mm 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 150mm fork no problem. Bottom line – max axle to crown measurement of 564mm. 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 SB120? The short answer is the SB120 can accept up to a 2.6″ tire. There is great tire clearance on the SB120 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 SB120 to accommodate a standard sized water bottle inside the front triangle for sizes MD-XXL. Size XS will fit Yeti’s 15oz Hot Lap bottle and size SM will fit standard 21oz bottles. We recommend using a side-entry cage for easiest access.
WHAT CRANKS AND BOTTOM BRACKET CAN I USE ON THE SB120? The SB120 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 SB120? The SB120 is designed to work exclusively with SRAM’s Universal Derailleur Hanger at 12x148mm spacing. This axle had 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 SB120 USE? The SB120 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.

FREQUENTLY ASKED QUESTIONS (2 OF 2)

SB120 | OWNER’S MANUAL

HOW BIG OF A ROTOR WILL FIT ON THE FRAME? The SB120 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 SB120? Yes. The SB120 has routing options for stealth only.
WHAT CHAINLINE WAS THE SB120 DESIGNED AROUND? The SB120 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 SB120? 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 SB120 HAVE ISCG MOUNTS? Yes. The SB120 has an integrated 2-bolt ISCG ’05 mount. It is designed to work best with lowprofile 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 SB120 USE? The SB120 uses a 190 x 45mm shock. The shock can also be locked out if you so desire, but we recommend running it fully open for the best compliance and traction.
WHAT TYPE OF SHOCK HARDWARE DOES THE SB120 USE? The SB120 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://www.yeticycles.com/ gear/parts/shock-eyelet-spacer
CAN I PUT A COIL SHOCK ON MY SB120? No, the SB120 will not fit a coil shock due to sizing constrictions and limited frame clearance in the bike’s link.

WHAT PERCENTAGE SAG DO YOU RECOMMEND FOR THE SB120? We would advise starting with 30% sag, or 13.5mm 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 SB120 USE? The SB120 uses a 31.6mm seat post.
WHAT SIZE SEAT COLLAR DOES THE SB120 USE? The SB120 uses a 36.4mm seat collar.
WHAT IS THE WARRANTY ON MY SB120? The SB120 has a LIFETIME manufacturer’s warranty.
WHAT IS THE LONGEST TRAVEL DROPPER POST I CAN RUN ON THE SB120? This is mostly defined by your inseam. There is no frame limitation, so in theory, 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. Your local Yeti dealer can help you sort this out. We run 150mm drop on SM-XS frames, 175mm on MD and 200mm drop on LG-XXL.
CAN I CONVERT THIS BIKE INTO A “MULLET” BIKE AND PUT A 27.5″ WHEEL ON REAR OF THE SB120? 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.
