Yeti Cycles SB140 LR T2 Eagle 90/X0 Carbon Wheel Mountain Bike

Crush tech trails with the SB140 29 LR T2 90/X0—agile, plush, and trail-hungry

What Our Gearhead® Experts Are Saying:

"I’ve been lucky to get extended time on the SB140 29 LR with the T2 X0/90 kit and upgraded EXC 1501 carbon wheels, and it’s a rocket. The TURQ carbon frame and Switch Infinity V2 platform keep it ultra responsive on climbs, while the 160/140mm suspension combo begs to charge into steeper, rowdier descents. This setup seriously blurs the line between a trail bike and an all-mountain weapon."

Whether we’re chasing high-alpine ribbons of dirt or threading through dense forest singletrack, the SB140 29 LR T2 90/X0 brings balance to every line. Yeti’s TURQ carbon frame and Switch Infinity V2 platform feel composed and efficient under pressure, giving us the confidence to ride deeper, longer, and with less compromise.

Up front, a 160mm FOX Factory 36 GRIP X2 fork paired with 140mm of FOX FLOAT X rear travel means we’re well-equipped to tackle technical descents and square-edge hits without sacrificing responsiveness. The upgraded DT Swiss EXC 1501 carbon wheelset drops weight and boosts lateral stiffness—climbing feels snappy, and tracking stays locked even in off-camber compressions. SRAM’s 90/X0 Transmission keeps shifts smooth and rock-solid, even under load, and Code RSC brakes haul us down in a flash. This bike’s ready to play hard and fast, all day.

Heads up — We do our best to keep bike specs and images current, but occasional component changes can happen without warning—and sometimes the photos might not show the exact build you’ll receive. If you want to double-check the details, our Gearheads are always here to help.
