With its 2017 SB6 Carbon Eagle Complete Mountain Bike, Yeti takes advantage of trickle-down technology in its choice to split its frame lines into standard Carbon and advanced Turq models this year, with the SB6 Carbon falling into the former category. Don't be mistaken though—this SB6's carbon construction is still top notch, and is a testament to just how far the industry has come with carbon. It's just a little bit heavier than the highest of high grade Turq, which means you're getting a bomber bike at a more attainable price point for the sacrifice of a mere claimed 260g, which is about the weight of a small cup of coffee if we put it in real world terms. Yeti pairs the SB6 frame with SRAM's new X01 Eagle drivetrain, which gives the surprisingly capable chassis an ultimate bailout gear in the form of a 50t cog.
The Switch Infinity suspension system is a key element behind the SB6's versatility. Switch Infinity originally replaced the Switch Link design, which experienced 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.
Aside from these updates, the two 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.
Yeti's carbon fiber ethos maintains 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 handle steep, lumpy terrain with ease and speed.

I had a chance to ride the Yeti SB6 in Moab, Utah at the biannual bike extravaganza known as Outerbike. Everyone there wanted to test the new SB5+ so the SB6 was easier to get my hands on. I have tested older models of this bike but with the updated Boost hub spacing, Eagle 1x12 drivetrain and forever evolving Switch Infinity pedaling platform this is by far the best iteration to date. The only thing you lose with this particular model is the Carbon frame is about 265g heavier than the Turq version. We rode Magnificent 7 which has a little of everything that Moab has to offer: smooth/buff berms, drops, slickrock, technical climbs and rocky, loose descents. I have been working on a modified rating system for all the bikes I have tested and here is my breakdown for the SB6:
Plowability - 9
Climbability - 7.5
Maneuverability - 8.5
Wheelie Rating - 7.5
Closest Competitors: Santa Cruz Bronson, Pivot Mach 6
Feel free to contact me directly with any questions on the SB6, Turq frames or any other Yeti bikes. If you are interested, I would be glad to help you build your next dream bike from the frame up. Also check out my article on "How to Choose a Mountain Bike" for additional info.
See you out on the dirt.

This build is perfect for those who are looking for one of the best enduro bikes of 2017, and don't want to break the bank. If you expect the high performance descending and perfectly capable climbing of the SB6 Turq, and are willing to gain a little weight to save a few bucks, this bike is for you!
The SB6 Carbon is the less expensive of the two carbon layups (albeit, still very high quality carbon) that Yeti offers for their 2017 SB6. However, don't discount this bike's ability perform! Coupled with the X01 Eagle drivetrain, there's not much this bike can't handle. It was born and bred to descend like a monster and the Switch Infinity suspension system and ridiculously high gear ratio maintains pedaling efficiency for a bike with this geometry. The SB6 has a longer wheelbase and slacker head tube angle than the SB5; making descending through any terrain a breeze. The trade off, compared to the SB5, is that it doesn't climb quite as nimbly. With that being said, the SB6 climbs better than most bikes in its category. I was super impressed with efficiency of the pedal strokes and its ability to get up and over rocks and roots on the climbs.
I'm 5'9" and I found the medium to fit me perfectly. Please feel free to contact me directly with any questions or to discuss sizing.
