FREQUENTLY ASKED QUESTIONS (2 OF 2)
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 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 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,
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.

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.
