Yeti SB140 LR T2 Bike

The Yeti SB140 LR T2 Bike is what Yeti calls "the mountain bike" — not a trail bike hedging between efficiency and capability, but a machine purpose-built to handle both without apology. The SB140 runs 140mm of rear travel on a TURQ-Series carbon frame built around Yeti's Switch Infinity V2 suspension, paired with a Fox Factory 36 Grip X2 fork up front at 160mm. The T2 build puts a SRAM Eagle X0/90 Transmission drivetrain and full Fox Factory suspension under you, which means this bike is ready for the kind of terrain that gets called "too technical" on lesser rigs.

At the heart of the SB140 is Yeti's Switch Infinity V2 — a next-generation translating pivot suspension design that resets expectations for kinematics, small-bump sensitivity, and long-term durability. The TURQ-Series carbon frame is constructed with size-specific carbon layups that are individually tuned to deliver consistent torsional stiffness and chassis flex across every frame size. Whether you're on the small end of the range or the large, the feel is precise, compliant, and composed in the same way. The frame includes a threaded aluminum bottom bracket shell with integrated ISCG-05 tabs for a chainguide mount, internally tunneled cable routing with secure port closures that eliminate cable rattle over rough ground, and a Universal Derailleur Hanger (UDH) so a replacement is available at virtually any shop.

The SB140's suspension runs a near-linear progression curve with slight ramp-up at the end of travel — 14% progressivity — delivering quality small-bump sensitivity, a supportive mid-stroke, and a composed feel when the terrain demands every millimeter of travel. Yeti's patented compact wishbone shock extender positions the Fox Factory Float X forward in the frame, which opens up space for two internal water bottle mounts, reduces stand-over height, and expands shock compatibility options without any downside on performance. The geometry is designed with a forward-bias posture: size-specific seat tube angles keep riders efficiently centered over the pedals on climbs, while size-specific chainstays ensure the rear center of the bike scales proportionately with the rider. On an XL frame, that translates to a 65.4° head angle, 510mm of reach, and a 631mm stack — numbers that inspire confidence at speed while staying manageable on the way up.

Design Benefits

1. Switch Infinity V2 suspension — Yeti's proprietary translating pivot design sets the standard for suspension kinematics at this travel range: active under power, sensitive on small bumps, and composed when the trail turns serious. The V2 generation improves on longevity and feel over the already well-regarded original.
2. TURQ-Series carbon with size-specific layups — the frame is individually engineered at each size for matching torsional stiffness and chassis flex, so every rider gets the same precise, compliant character regardless of where they fall in the size range.
3. Fox Factory 36 Grip X2 fork + Fox Factory Float X shock — full Factory-grade suspension front and rear. The 36 platform handles the aggressive trail geometry and Minion tire package with authority, and the Float X shock has the damping range to match whatever conditions you're riding into.
4. SRAM Eagle X0/90 Transmission drivetrain — the mixed X0/Eagle 90 T-Type spec puts a stiff, chain-drop-resistant drivetrain under the bike. The 30T front ring with 10-52 cassette handles long climbs and extended descents without running out of range at either end.
5. Patented wishbone shock mount and full-travel dropper — Yeti's compact wishbone extender keeps two water bottle mounts accessible inside the frame while enabling 200mm dropper posts on larger sizes. Tire clearance runs to 2.6", leaving room to run more rubber than the stock Minions if the terrain calls for it.

Final Take

The SB140 LR T2 is for riders who want a trail bike that doesn't flinch. The TURQ-Series carbon frame, Switch Infinity V2 suspension, Fox Factory suspension package, and Maxxis Minion tire spec all point in the same direction: a bike built to go deep into technical terrain and come back wanting more. The T2 kit is the entry point to the full TURQ SB140 experience, and at $7,700 it's a strong one. If the plan involves sustained climbs followed by consequential descents, this is the build that holds up on both sides of the day.
