OWNER’S MANUAL

HOW BIG OF A ROTOR WILL FIT ON THE FRAME?
The SB135 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 SB135?
Yes. The SB135 has routing options for stealth only.
WHAT CHAINLINE WAS THE SB135 DESIGNED AROUND?
The SB135 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.
Minimum clearance from the chainring teeth to the chainstay must be 3.5mm.
WHAT IS THE MAX SIZE SINGLE-CHAINRING THAT FITS ON THE SB135?
Without getting too technical, the max chainring size depends on the crank chainline and the
chainring shape. Minimum clearance from the chainring teeth to the chainstay is 3.5mm.
• Shimano / SRAM 55mm chainline Boost cranks: 34t round / 32t oval
• Minimum Chainring Size: 28t round / 30t oval

DOES THE SB135 HAVE ISCG MOUNTS?
Yes. The SB135 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 chainguide to confirm
compatibility.
WHAT TYPE OF SHOCK DOES THE SB135 USE?
The SB135 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. Note that sizes
XS and small are not compatible with piggy back style shocks due to limited clearance in the
front triangle.
WHAT TYPE OF SHOCK HARDWARE DOES THE SB135 USE?
The SB135 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,
CAN I PUT A COIL SHOCK ON MY SB135?
Yes, M-XL size SB135s are designed to be compatible with both air and coil-sprung shocks.
Sizes XS and small are not compatible with piggy back style shocks due to limited clearance
in the front triangle.
WHAT PERCENTAGE SAG DO YOU RECOMMEND FOR THE SB135?
We would advise starting with 30% sag, or 16.5mm 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 COLLAR DOES THE SB135 USE?

WHAT IS THE WARRANTY ON MY SB135?
The SB135 has a LIFETIME manufacturer’s warranty.
WHAT IS THE LONGEST TRAVEL DROPPER POST I CAN RUN ON THE SB135?
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 tire rubs on your saddle or your dropper
bottoms out in the frame. Your local Yeti dealer can help you sort this out. We run 150mm
drop on XS-SM frames, 175mm drop on MD and a 200mm drop on LG-XL. See the owners
manual for a more detailed fit check procedure.
CAN I CONVERT THIS BIKE INTO A “MULLET” BIKE AND PUT A 29” WHEEL AND FORK ON THE FRONT
OF THE SB135?
Yes but it does change the GEO quite a bit. Headtube angle and seat tube angle gets 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.
HOW CAN I TELL WHICH SB135 LINK IS NEEDED FOR EACH SIZE OF SB135 FRAMES?
The SB135 uses two different links between all the sizes offered. XS and SM frames use link
part number 200020426 and is designated by two dots on each side of the link. MD, LG, and
XL frames use link part number 200020427 and is designated by two dots on the drive side
of the link.
