Yeti MT Details: Ditching Switch Infinity for Simplicity

For the better part of a decade, the SB130 and SB140 were the pinnacle of versatility in Yeti's catalog of mountain bikes; the geo was on point, and the Switch Infinity suspension design let it cash some pretty big checks. So how do you make such a capable bike better? Surprisingly, Yeti decided to ditch the Switch Infinity design for a new layout that has been in the works for almost 10 years.

The result is Sixfinity, which recently graced the Yeti LT, a long-travel enduro machine, and now breaks ground with a 140mm-travel trail bike that has everyone talking. Here is the what, why, and how of the all-new Yeti MT.

The new Yeti MT is a trail bike designed to replace the wildly popular SB130 and SB140 models, as we just went over. It is built to climb efficiently while handling aggressive, loose descents without compromise, thanks to the new Sixfinity suspension design.

As we saw with the LT , Yeti is moving away from the Switch Infinity design and adopting the new Sixfinity system, a 6-bar design that allows for finer tuning of the suspension kinematics, making a bike that not only climbs better but descends better, too. It's just better. This change also makes for a more maintenance-friendly bike by sunsetting the sliding links found in the Switch Infinity system.

• Travel:140mm rear / 160mm front

• Wheel Size:29-inch

• Frame Material:TURQ Series Carbon (with new Vectran reinforcement)

• Bottom Bracket: Threaded BSA

• Price: $11,500 USD – $8,000 USD ($4,600 USD Frame/shock)

Unlike the Yeti LT, the MT is a little less complex, with only one flip-chip, no MX wheel compatibility, and a more versatile travel range. However, the MT borrows more design features than just the Sixfinity from the MT, including proportional chainstays and a taller stack height across sizes.

The Yeti MT Build Kits and Geometry

The geometry is as you'd expect from a bike in this arena, with a 64.5-degree headtube angle and a 77-degree seat tube angle. The stack is also a tad higher, and the ZS44/56 headset means you could run a reach-adjust headset if needed.

The price is also predictably "Yeti", with the top-tier build coming in at $11,500 USD for full SRAM XX AXS and the "cheapest" option being $8,000 USD for a mix of SRAM Eagle 90 and XO. What I find interesting is that for only $500 USD more, you could upgrade to the Shimano XT Di2 build. There is also a frame/shock (Fox Float X) option available for $4,600 USD if you want to build a custom bike.

Yeti MT Overview

The Yeti MT and LT signal a massive shift in Yeti's trail bike lineup. By stepping away from the long-standing SB naming convention and Switch Infinity platform, the MT brings the top-tier, downhill-bred Sixfinity suspension into a versatile, all-day 140mm trail machine that looks really appealing.

The Move to Sixfinity Suspension

The most significant change to the MT is the retirement of Yeti's iconic Switch Infinity suspension platform (which had been standard since 2014). The MT adopts the Sixfinitysix-bar suspension layout.

This design drives anti-squat up hard through the pedaling zone for highly efficient climbing, and drops it off sharply deeper in the stroke so the rear wheel tracks perfectly and feels loose and forgiving on rowdy descents.

Three-Position Flip Chip

Unlike the recently released LT, the MT is much less adjustable, with just one flip chip at the lower shock mount. The MT has a tunable leverage rate via this flip chip, allowing riders to switch among three leverage curves. Crucially, adjusting this chip changes the suspension feel (from supportive/efficient to extra bottom-out resistance) without altering the bike's geometry, head angle, reach, or anti-rise.

"The Cavity" In-Frame Storage

To meet modern trail bike demands, Yeti has introduced The Cavity, a nice nod to the running joke that only dentists can afford Yeti bikes. This is a fully integrated downtube storage compartment that lets you stash tools, a spare tube, or an extra layer directly in the frame, helping you ditch the riding pack.

Vectran-Reinforced Carbon Layup

Yeti is utilizing a new layup for the MT's TURQ series carbon frame that integrates Vectran. This specialized reinforcement adds significant impact strength and durability to the frame, particularly against rock strikes, without adding noticeable weight to the overall build.
