The SB140 is Yeti's most versatile bike, hitting the sweet spot between efficient pedalling kinematics and aggressive geometry. It mixes the disciplines of mountain biking to create the ultimate trail bike, and these Lunch Ride builds add extra spice with more front travel, making the bike even keener on rougher trails and bigger features.

The 29" SB140 frame is packed with Yeti's race-proven design knowledge. At its core is a 140mm rear travel platform using the updated Switch Infinity system, paired here with a 160mm fork (standard models run 150mm). It's a perfectly balanced combination that makes easy work of all kinds of trail.

Switch Infinity uses a patented translating pivot that changes direction as the bike moves through its travel. Through the pedalling zone it moves up, giving a flat, high anti-squat curve for an efficient, consistent platform; deeper in the travel it reverses, and anti-squat drops away to let the suspension move freely.

There are two builds. The T3 uses Yeti's TURQ Series carbon, its finest layup, for the best balance of stiffness, compliance and finish. The C2 uses C-Series carbon with identical geometry but a different layup, making it more affordable at the cost of a little extra weight, and C-Series bikes now come with FOX Factory suspension.
