SB120 LR T3 X0 Transmission Mountain Bike

What Our Gearhead® Experts Are Saying:

"I reach for the SB120 when I want an efficient pedaling bike that can still land big hits without flinching. The 140mm Pike pairs perfectly with the 120mm rear travel, giving it noticeably more stability than a traditional short-travel platform. The Transmission drivetrain is a huge plus—it shifts cleanly under load and feels mechanically solid. It’s a perfect choice for riders who love technical terrain but want XC-style speed."

The SB120 LR T3 X0 Transmission blends lightweight efficiency with trail-focused capability, giving riders a bike that feels razor sharp on climbs and composed on fast, technical downs. Its TURQ carbon chassis delivers stiffness where hard efforts demand it while maintaining the compliance needed for long days tackling mixed surfaces. The Switch Infinity V2 system enhances mid-stroke support and traction, helping the bike stay lively when pedaling and predictable when the terrain breaks loose.

This build adds a 140mm RockShox Pike Ultimate fork and a RockShox Super Deluxe Ultimate rear shock for a more confident front end and improved small-bump sensitivity. SRAM’s X0 Transmission drivetrain brings durable, full-power shifting, while the DT Swiss XM1700 wheelset offers dependable strength for fast, aggressive riding. With Maxxis tires chosen for grip and rolling speed, plus a size-specific Fox Transfer post, it’s designed for riders who want a bike that pushes into trail-bike territory while keeping the nimble character of a short-travel machine.
