2026 Yeti SB165 T2 X0/90 Transmission

The 2026 Yeti SB165 T2 X0/90 is the ultimate enduro and big-mountain weapon—crafted for riders who seek the steepest descents, the deepest travel, and unshakable confidence when the trail drops away. With a TURQ Series carbon frame as its foundation, this bike delivers maximum strength and stiffness while keeping weight impressively low. Yeti’s legendary Switch Infinity suspension technology works in harmony with its progressive geometry to offer an unparalleled balance of plush small-bump sensitivity, supportive mid-stroke, and bottom-out control—ensuring every inch of its 165mm rear travel is dialed for aggressive riding.

Frame & Suspension

It's built on a top-of-the-line TURQ Series carbon fiber frame, engineered for durability and precision handling. TURQ Series frames are Yeti's best frame option. They're made with the highest-quality carbon fiber, and designed for the perfect balance of stiffness and compliance. They're built to handle aggressive riding while remaining solid and smooth, and are tested by some of the best racers in the world to ensure they're up to spec.

The Switch Infinity suspension, tuned specifically for the SB165, smoothly adapts to terrain changes, maintaining traction and efficiency while devouring rock gardens, drops, and chatter. Internally tunneled cable routing keeps the lines clean and quiet, while sealed Enduro Max pivot bearings ensure longevity under hard use.

The suspension setup is pure big-hit performance: up front, the Fox Factory 38 Grip X2 fork offers 170mm of travel, delivering stiffness, adjustability, and control for the rowdiest tracks. In the rear, a Fox Factory DHX2 coil shock (with size-specific spring rates: SM 400#, MD 450#, LG 500#, XL 550#) adds unmatched suppleness and consistency for downhill-charging confidence.

Drivetrain

The SB165 T2 X0/90 comes equipped with SRAM’s Eagle Transmission—a direct-mount, hangerless drivetrain for unmatched precision and durability. The X0 Eagle Transmission crankset (30t, 170mm) pairs with the X0 cassette and Flattop chain for smooth, crisp shifting under full load. The Eagle 90 Transmission derailleur and shifter offer electronic shifting with instant responsiveness, so you can focus fully on the ride. Power transfer comes through a SRAM DUB BSA 73 bottom bracket, ensuring rock-solid performance.

Wheels & Tires

Confidence starts with the wheelset, and the SB165 delivers with DT Swiss Custom EX1700 30mm rims—light enough for long days but strong enough for bike park laps. Rubber choice is pure enduro gold: a Maxxis Assegai 2.5 EXO+ fronts the bike with unbeatable cornering grip, while a Maxxis Minion DHR II 2.4 Double Down anchors the rear with superior braking traction and durability.

Braking Power

Stopping is handled by SRAM Maven Silver brakes, delivering top-tier modulation and brute-force stopping power—paired with 200mm Centerline rotors front and rear to keep control on even the steepest chutes.

Cockpit & Contact Points

A Yeti Carbon 35x800mm handlebar and Burgtec Enduro MK3 35x50mm stem provide a stable, responsive front end. A Cane Creek 40 integrated headset ensures smooth steering feel, while a WTB Silverado Custom saddle balances comfort and performance for long days out.

For dropper duties, the Fox Transfer seatpost comes in size-specific travel lengths—150mm (SM), 175mm (MD), and 200mm (LG–XL)—ensuring optimal fit and clearance no matter your frame size.

The Bottom Line

The 2026 Yeti SB165 T2 X0/90 is bombproof, big-mountain machine for riders who live for the edge. With a premium carbon chassis, coil-sprung suspension, cutting-edge SRAM Transmission drivetrain, and bulletproof DT Swiss wheelset, it’s designed to handle the roughest lines with poise and speed. Whether you’re charging blind enduro stages, dropping into gnarly freeride zones, or smashing bike park laps, the SB165 gives you the confidence to send it bigger and ride it faster.
