Big shoes to fill.

Given the implications of its mythological mascot's large footprints, it's little surprise that Yeti Cycles is among the first manufacturers to adopt the new, stiffer, extra-wide Boost rear hub standard. It's also a given that, of the venerable brand's stable, the first model to make use of it would be the SB6 in 2016, with changes carrying over to the 2017 SB6 Carbon Mountain Bike Frame, easily recognizable on enduro podiums the world over as Yeti's flagship sled. With geometry that's proven powerful, it's not surprising that Yeti opted not to make big changes to the SB6 when it was boosted in 2016, choosing to give it a swap in shock to the favored FOX DPS model, but keeping things feeling just as plush and capable that has proved to be a fan favorite. We're left with a frame that's a bit of an enigma. Is it an enduro sled? A short-travel DH rig? A plush backcountry charger? All of the above? We're not sure we're prepared to answer those questions, but we do know that Yeti's large footprint and Switch Infinity suspension keep it floating over the earth, regardless of the terrain ahead.

The Switch Infinity suspension system is a big reason why the SB6 is so versatile. Switch Infinity originally replaced the Switch Link design, which experiences a momentary harshness when rapidly successive hits kept it hovering above the 30% stroke point. The new design has a more linear travel arc, so the eccentric link changes direction without getting caught in that minute dead spot. Of course, 95% of all riders won't ever push the Switch Link hard enough to experience this dead spot, but Yeti (being Yeti) went ahead and fixed it anyway. For those of us who are our own mechanics, Yeti also simplified maintaining the Switch Infinity by including easily accessible grease ports, which do away with the need for time-consuming rebuilds.

Other than those two changes, the suspension systems are fairly similar. Like the Switch Link, the Switch Infinity slider travels upward under the first phase of compression, when the SB6 is settling into its sag point. As the rear end compresses deeper, the direction changes, and the DH-inspired slider travels down toward the bottom bracket shell to maintain a steady pedaling platform. This change of direction is smoother, without the above-mentioned dead space, but the effect is the same. Deep in the stroke, it works in conjunction with the upper pivot to produce a vertical wheel path that effortlessly flattens big, square-edged impacts.

The SB6's frame itself returns with minimal changes. There is, of course, the rear triangle, which bulks out to accommodate a Boost axle, but the basic construction is the same. Yeti's carbon fiber ethos involves maintaining a focus on increased efficiency and decreased weight while dialing the geometry to its signature enduro standards. This involves dropping the head tube angle to a slack 65.5 degrees — down a full degree-and-a-half from Yeti's more trail-minded SB5. That, combined with the long top tube, makes for a long, low ride that can't help but charge down steep and chundery terrain with power and speed.

  • Drop-in like a sasquatch with Yeti's enduro monster
  • Switch Infinity is the missing link in suspension design
  • Slack 65.5-degree head tube for conquering descents
  • Long cockpit adds stability to the most foolhardy line selections
  • Carbon fiber construction for sleek lines and stiff tracking
  • Boost rear axle leaves a huge footprint
