2023 Yeti SB140 29″ Inventory

A 29er for mountain and trail domination.

The 2023 Yeti SB140 29" is a bike for the most untamed mountains and trails. You can ride as deep as you want to discover what's on the other side. A new model also means new features. A different frame silhouette with a high-clearance downtube, for - you guessed it - even better ground clearance.

The downtube has protection, too. If you do hit something, there's no damage. Fully enclosed cable routing keeps things tidy while preventing rattling and cable rub. The universal derailleur hanger pivots back and out of the way to protect your derailleur against chain jams.

Standard sized Enduro Max bearings are housed in the pivot linkages instead of the frame. You're much less likely to damage the frame when you have to replace them. Not to mention, the bearings can be found at almost any bike shop, Yeti dealer or not. It's the same with the UDH.

Worried about the bike not fitting you? No need. The frame comes in small to extra-extra-large to fit a wide range of heights. Everyone gets the same level of performance with the size-specific seat tube angles and chainstay lengths. The wishbone shock extender is for optimal clamping and shock compatibility.

Other highlights include DT Swiss XM Wheels, 4 piston brakes, and ODI Elite Pro grips. Plus two new colorways, Sangria and Sage. In addition to the famous Yeti Turquoise and Raw Carbon. That way, your riding companion can match your personality.

  • What's the difference between TURQ and Carbon Series SB140?

    TURQ Series bikes have the highest quality carbon fiber available to optimize their weight, stiffness and durability. Carbon Series bikes have a modified carbon fiber layup. So they have the same stiffness and durability, but they weigh more.
