What is the difference between the TURQ and Carbon series SB115?
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 SB115 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 http://www.ridefox.com/SB100.
What was updated in the SB115 Switch Infinity?
The look and layout of our Switch Infinity mechanism was changed to best work with our shorter travel 115mm platform. Both Switch Infinity designs utilize a translating pivot point that allows us to tune the suspension kinematics to our desired characteristics. The SB115Switch Infinity link is rotated 90 degrees to allow for slimmer, more efficient packaging and is lighter than the previous design. TheSB15 Switch Infinity uses its own hardware but function is identical between both Switch Infinity designs.
Can I replace or modify any Yeti frame parts on my SB115?
All replacement frame parts for your SB115 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 SB115?
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 SB115?
The SB115 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 angleset was installed on the frame and all liability will be assumed by the customer. See “What travel fork is the SB115 designed to use” for more information.
What travel fork is the SB115 designed to use?
The SB115 is designed to run a 130mm travel fork. We test our frames 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. It 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 SB115?
The short answer is the SB115 can accept up to a2.3" tire. There is great tire clearance on the SB115 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 SB115 to accommodate a standard sized water bottle inside the front triangle. We recommend using a side-entry cage for easiest access.
What cranks and bottom bracket can I use on the SB115?
The SB115 bottom-bracket standard is PF92 [92mm] 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.
How many BB spacers do I need?
The SB115 has a 52mm chain line. For the SRAM DUB PF92 BB you will need a 2mm clip on spacer on the drive side and no spacers on the non-drive side for a SRAM DUB crankset with a 52mm chain line. For a Shimano PF92 BB you will need no spacers when using a Shimano 52mm chain line crank.
What rear wheel axle fits on my SB115?
The SB115 is designed to work exclusively with a Yeti or Shimano 148mm X 12mm E-Thru rear axle. The frame’s rear triangle has been optimized for stiffness and weight with these specific axles.
What type of headset does the SB115 use?
The SB115 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 SB115 has a direct mount rear brake tab and can run a 160mm rotor without the need for a brake adaptor. With the use of a brake adaptor the frame can accept up to a 180mm rotor.
Why are there composite frame guards on the SB115?
The SB115 has great impact resistance, but we have added composite frame guards to the SB115 frame for additional protection against any stray rocks and roots that you may encounter on the trail.
Can I run a stealth seatpost dropper on the SB115?
Yes. The SB115 has routing options for stealth only.
What chainline was the SB115 designed around?
The SB115 was designed around a 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 SB115?
Without getting too technical, the max chainring size depends on the crank chainline and the chainring shape.
Shimano / SRAM Boost cranks: 36t round / 34t oval
RaceFace 52mm Chainline: 36t round / 34t oval
Minimum Chainring Size: 26t round / 28t oval

Does the SB115 have ISCG mounts?
Yes. The SB115 has an integrated 2-bolt ISCG ’05 mount. 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 SB115 use?
The SB115 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 SB115 use?
The SB115 uses M8x25mm hardware on the air can side and M8x30mm hardware on the shaft side.
Can I put a coil shock on my SB115?
No, the SB115 will not fit a coil shock due to sizing constrictions and limited clearance in the bike's link.
What percentage sag do you recommend for the SB115?
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 32% 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 collar does the SB115 use?
The SB115 uses a 35.0mm seat collar.
What is the warranty on my SB115?
The SB115 has a LIFETIME manufacturer’s warranty.
What is the longest travel dropper post I can run on the SB115?
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 125mm drop on SM frames, 150mm on MD and 175mm drop on LG/XL.
Can I convert this bike into a "mullet" bike and put a 27.5" wheel on rear of the SB115?
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.
Can I convert my SB100 to the same travel as the SB115?
While this is technically possible, we do not recommend it. While the bikes are similar in geometry, there are significant engineering differences between the two models that make a safe conversion complicated and, possibly dangerous to the rider and detrimental to the integrity of the frame and Switch Infinity assembly if done improperly.
