Yeti reveals the new MT featuring 140mm of Sixfinity rear travel, 160mm Fox 36 fork, and Turq Series carbon frame. Full specs, global pricing, and technical details.

AT A GLANCE: QUICK SUMMARY

    Market Positioning: The new Yeti MT officially replaces the popular SB140, positioning itself as the most versatile, high-performance 29er trail bike in the Colorado brand's lineup.

    Sixfinity Suspension: Bids farewell to the Switch Infinity linear slider to adopt the 6-bar linkage platform derived from Yeti's e-MTBs (160e) and World Cup DH race program under Richie Rude, drastically reducing routine maintenance.

    Travel & Geometry: Features 140mm of rear travel paired with a Fox Float X shock and a 160mm Fox 36 fork. Built around a 64.5-degree head tube angle and a 77-degree effective seat tube angle.

    Adjustable Kinematics & Size-Specific Stays: A 3-position flip chip at the shock mount alters progression (10%, 15%, or 20%) without shifting geometry. Chainstay lengths scale by frame size (436mm on Small to 452mm on XL).

    Frame & Features: Built exclusively from top-tier Turq Series carbon reinforced with Vectran. Features internal down-tube storage, a custom frame bag, top-tube accessory mounts, and an integrated AirTag/Tile tracker recess.

New Yeti MT: World Cup-Bred Sixfinity Kinematics Land in Trail Territory

Yeti Cycles has revamped its pedal-powered trail lineup with the unveiling of the all-new Yeti MT. Succeeding the highly regarded SB140, the MT arrives as a 140mm rear-travel 29er trail machine spec'd with a 160mm front fork, designed to bridge the gap between all-day alpine epics and aggressive trail riding.

Following the launch of the longer-travel LT earlier this year, the MT is Yeti's second non-assisted model to adopt the Sixfinity suspension platform. This six-bar linkage system systematically replaces the legacy Switch Infinity design first introduced in 2014, marking a major engineering evolution that also simplifies maintenance routines by utilizing standard sealed cartridge bearings.

Inside Sixfinity: Redefining Trail Kinematics

Developed over more than a decade of testing and proven under World Cup DH champions like Richie Rude, the Sixfinity platform uses six links to manage the rear wheel axle path and leverage rate.

By moving away from the translating slider mechanism of Switch Infinity, Yeti's engineers were able to decouple critical suspension characteristics:

    Optimized Anti-Squat: Anti-squat is tuned to provide crisp pedaling support around sag before dropping away smoothly deeper in the travel to eliminate pedal kickback and keep the suspension active on rough descents.

    Tuned Anti-Rise: Anti-rise has been tuned slightly lower than on the outgoing SB140, maintaining active traction and chassis stability under hard braking over chunder.

    3-Stage Progression Adjustment: A 3-position flip chip at the shock mount allows riders to tune leverage progression to 10%, 15%, or 20%. This adjustability allows seamless tuning for air or coil shocks without altering head angles, bottom bracket height, anti-squat, or anti-rise values.

Progressive Geometry & Size-Specific Rear Centers

The geometry of the Yeti MT reflects modern aggressive trail demands: a slack 64.5-degree head tube angle is paired with a steep 77-degree effective seat tube angle to deliver an upright, efficient pedaling stance on technical climbs. Up front, a 160mm Fox 36 handles trail duties.

Crucially, Yeti treats each frame size as an independent engineering project rather than just scaling up tube lengths. Rear center lengths scale dynamically across the size range:

    Size Small: 436mm chainstays

    Size Medium: 440mm chainstays

    Size Large: 448mm chainstays

    Size XL: 452mm chainstays

Turq Carbon Chassis, Down-Tube Storage & Radial Rubber

The Yeti MT is offered exclusively in Yeti's flagship Turq Series carbon, which incorporates Vectran fiber reinforcement in high-impact zones to bolster frame durability. In addition, all complete builds come stock with Schwalbe’s latest Radial casing tires (Albert Trail Pro up front and Romy Trail Pro at the rear) to maximize tire deformation and mechanical grip on technical terrain.

Key frame integration details include:

    Internal Down-Tube Storage: Built-in storage portal complete with an included custom Yeti protective frame bag.

    Accessory Mounts: Dedicated top-tube accessory mount for tools or tube straps.

    Security Integration: Embedded internal housing designed specifically for Apple AirTag or Tile tracking devices.

Frequently Asked Questions

Does the Yeti MT fully replace the SB140?

Yes. The Yeti MT officially takes over the 140mm trail category in Yeti's catalog, replacing the SB140. It updates the platform with the new 6-bar Sixfinity linkage and modern frame features while stepping away from the Switch Infinity linear slider.

What are the practical maintenance benefits of Sixfinity over Switch Infinity?

Sixfinity replaces the dual stanchion slider mechanism of Switch Infinity with traditional linkages rotating on sealed cartridge bearings. This significantly reduces mud buildup, eliminates slider seal wear, and makes routine frame servicing far simpler for riders.

Can I run a coil shock on the Yeti MT?

Yes. Thanks to the 3-position flip chip at the shock mount, riders can switch the leverage rate progression to 20%. This higher progressivity provides the necessary ramp-up to support coil shocks without harsh bottom-outs.

How does the Yeti MT differ from the Yeti LT?

The Yeti MT is a 140mm rear / 160mm front trail bike tuned for all-around agility and climbing efficiency. The Yeti LT is a long-travel enduro bike with increased travel and kinematics tuned to handle high-speed, heavy-impact terrain.

CyclOnline's Take

The Yeti MT confirms that the Sixfinity platform is not just a niche layout for e-MTBs or downhill race rigs, but the engineering blueprint for Yeti’s core trail lineup.

By eliminating the maintenance overhead of Switch Infinity, adding down-tube storage, and providing adjustable leverage progression without geometry compromise, Yeti has crafted one of the most refined trail bikes on the market. While pricing remains strictly premium, the performance of the Turq carbon chassis and Sixfinity layout makes the MT a standout contender in the modern 140mm category.
