Forget the numbers. Mute the speculation. Let the other guys invent cute alternatives for "Cross country". Steer clear of pigeon holes and limiting beliefs. Strap on your blinders and go get lost. Then decide what the SB120 means to you. And you alone. Definition ready.


LOOKS THE PART. BECAUSE IT IS.

With a new-gen approach to their shortest travel bike, the Yeti SB120 now has a frame silhouette that’s inspired by its longer legged siblings. Torsional precision and impact clearance has increased, without transferring unwanted feedback to the rider. And the refined Switch Infinity makes this bike punch well above its weight.

MORE BALANCED AT SPEED.

The nimble reach of the SB120 darts through singletrack. Its steep seat tube angle makes light work of climbs. Its head angle and balanced vertical suspension travel prioritize downhill fun, making it an incredible Trans-Cascadia style race whip. Point is, the SB120’s geometry is so balanced and agile, forgetting how much travel it has on the way up and down is totally possible.

A relatively linear progression curve gives riders usable, active travel at 30% sag – a far greater margin than other 120mm travel bikes. The SB120’s small bump compliance delivers incredible traction. Its supportive mid-stroke ensures riders don’t blow through travel when pushing against the suspension in turns or when getting the wheels off the ground. Oh shit moments are handled with ease – the curve has been tuned with increased bottom-out control.

Threaded BB - Threaded aluminum bottom bracket shell with integrated ISCG-05 tabs. This critical drivetrain interface is now more durable, cleaner, and easier to service.

Cable Management - Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub. Whether running a mechanical drivetrain and dropper or a wireless setup, cable management is intuitively easy and quiet.

Universally Ready - If a hanger bending crash occurs, the new Yeti models use the Universal Derailleur Hanger (UDH) interface — the industry standard mount for a rear derailleur. The UDH is available in nearly any bike shop, Yeti dealer or not.

WHAT TRAVEL FORK IS THE SB120 DESIGNED TO USE?

The SB120 is designed to run a 130mm travel fork. Yeti 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 150mm fork with no problem. Bottom line - max axle to crown measurement of 564mm. 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.

WHAT TYPE OF HEADSET DOES THE SB120 USE?

The SB120 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.

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 SIZE SEAT POST DOES THE SB120 USE?

The SB120 uses a 31.6mm seat post. In theory, you can run any travel dropper as long as you are above the minimum insert mark and you are not so low your tire rubs on your saddle. Yeti usually run 150mm drop on SM-XS frames, 175mm drop on MD, and 200/210mm drop on LG-XXL. (T4 kit uses a Fox Transfer SL Factory post with 125mm drop on XS-SM and 150mm drop on MD-XXL)

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.
