SB120 LR T3 X0 Transmission Mountain Bike

What Our Gearhead® Experts Are Saying:

"I’ve ridden the SB120 on everything from punchy desert singletrack to long alpine loops, and it keeps surprising me. The Switch Infinity V2 platform makes the rear end feel incredibly composed, especially when pedaling through rough sections. The 140mm Pike up front adds enough confidence for bigger moves without making it feel sluggish on climbs. With the X0 Transmission kit, the shifting feels bombproof—this build is the definition of a modern downcountry trail bike."

When we point the SB120 down rolling singletrack or wind it through tight forest climbs, we feel how balanced and confident a lightweight trail bike can be. Yeti’s TURQ carbon construction keeps the frame lively and efficient, while the upgraded 140mm fork gives this build the extra punch to stay playful on rock gardens, drops, and fast corners. From smooth ribbons of dirt to chunky high-country terrain, the SB120 is built for riders who like to cover big miles without sacrificing fun.

Switch Infinity V2 suspension is the heart of the bike, giving us traction, support, and stability on everything from technical climbs to flowy descents. Paired with SRAM’s X0 Transmission drivetrain, the bike delivers precise shifting even when we’re standing and hammering. With durable Maxxis tires, a reliable Fox Transfer post, and a dialed cockpit, this version of the SB120 is ready for long days and all-terrain adventure riding.

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.
