FEATURES

THE LOWDOWN ON THE SB140 AND ITS FEATURES

FRAME FEATURES

1. SWITCH INFINITY TECHNOLOGY PATENTED SUSPENSION SYSTEM
   • The SB140/LR delivers 140 MM of travel with our patented Switch Infinity Technology. Efficient pedalling performance while still smooth and continuous when the going gets rough.
2. HIGH MODULUS CARBON FIBER MAIN FRAME AND SWING ARM
   • High-modulus carbon provides a stiff, strong and lightweight chassis.
3. COLLET AXLE SYSTEM ON PIVOTS REDUCES BEARING WEAR
   • Collected pivot axles help create a stiff interface between the front and rear triangles of the frame. Custom Enduro Max sealed bearings keep things moving freely at the pivots.
4. OPTIMIZED FOR 1X DRIVETRAINS ONLY
   • The SB140/LR does away with the front derailleur mount, making it a 1x drive-specific frame. This increases stiffness in the frame.
5. ISCG 05 CHAINGUIDE MOUNTS
   • ISCG 05 chain guide mounts are included on the SB140/LR in case you want to go for some extra drivetrain security in the rowdy sections.
6. INTEGRATED HEAD TUBE (41MM/52MM)
   • Using our integrated head tube on the SB140/LR allows for a larger head tube with more area, increased stiffness, and lower overall ride height without compromising any performance.
7. SUSPENSION BY FOX
   • The SB140 uses a 210mm x 55mm Float DPS shock by Fox Racing Shox.
   • The SB140LR uses a 210mm x 55mm Float X shock by Fox Racing Shox.
8. CUSTOM DEBRIS AND CHAIN SLAP GUARDS
   • Custom guards on the seat stay, chain stay and down tube keep things quiet while riding and protect the frame.
9. INTERNAL CABLE ROUTING
   • The SB140/LR features internal routing for all cables, making the bike quiet and clean looking as well as reducing cable rub on the paint.
10. INTEGRATED AXLE AND DERAILLEUR HANGER SYSTEM
    • Dedicated 12 x 148 Boost dropouts and integrated hanger with axle threads for strength, stiffness, ease of hanger and wheel installation.

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 fibre layup of our TURQ Series bikes. By using different materials and tweaking the fibre layup, we can 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 190g 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 pedalling 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 website 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 SB140?
  • All replacement frame parts for your SB140 can be found through your local dealer or on our website. 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 cannot 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 mounted to your bike without any interference or play. Pay special attention to all the bike 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 anglesets available for this style of 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 150 mm 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 with no problem. Bottom line – max axle to crown measurement of 577mm. 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 TYRE CAN I FIT ON THE SB140?
  • The short answer is the SB140 can accept up to a 2.6” tyre. There is great tyre clearance on the SB140 but tyre 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 with a piggy-back shock. We recommend using a side-entry cage for the easiest access.
• WHAT CRANKS AND BOTTOM BRACKET CAN I USE ON THE SB140?
  • The SB140 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.
• WHAT REAR WHEEL AXLE FITS ON MY SB140?
  • The SB140 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 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.

FREQUENTLY ASKED QUESTIONS (2 OF 2)

• 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 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 chain line and the chainring shape. Shimano / SRAM Boost cranks: 34t round / 32t oval RaceFace / 52mm chain line Cranks: 34t round / 32t oval
• Minimum Chainring Size: 28t round / 30t oval Confused?
  • Ask your local dealer or call us at 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 chain guide 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 reservoir 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 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 pedalling 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 SB140?
  • 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 tyre rubs on your saddle or your dropper bottoms out in the frame. Your local Yeti dealer can help you sort this out. We run a 125mm drop on XS-SM frames, a 150mm drop on MD and a 200mm drop on LG-XL.
• CAN I CONVERT THIS BIKE INTO A “MULLET” BIKE AND PUT A 27.5” WHEEL ON THE REAR OF THE SB140?
  • Yes, but it does change the GEO quite a bit. The Headtube angle and seat tube angle get slacker and the bottom bracket gets higher. Some people will like these changes and some won’t but that is up to you to decide.
