Frequently Asked Questions - Yeti SB140/LR Owner's Manual

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 angleset 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 12x1.0 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.
