Top of the trail.
Drawing inspiration from light, nimble XC rigs and burly enduro sleds alike, the 2017 Yeti Cycles SB5+ Turq XT Complete Mountain Bike lands in the sweet spot as a snappy, responsive, trail bike that whips up to speed and handles burly terrain like the champ that it is. Its plus-sized tires add much appreciated grip through loose ground and dicey terrain, and its Shimano XT build kit and DT Swiss hoops mean it's ready to shred whether you're pinning on a number or heading out for a day of spontaneous adventuring.
The SB5+ Turq's geometry closely mirrors its smaller-tire SB5 sibling, with slight tweaks to embrace up to three-inch tires for smooth, stable traction across loose terrain. Of particular note is the SB5+'s elevated chainstays, which curve upward from the shock and create a sharply pointed triangle that increased stiffness and opens up tire clearance. This curved design keeps the chainstays at a svelte 17.2 inches for snappy, confident handling when whipping through switchbacks and rocketing over dusty trails.
The frameset carries Yeti's new Turq designation, which represents the brand's most advanced frame construction method. For the SB5+ Turq, that means a more precise carbon layup that's molded to reinforce key stress points along the frame without adding bulk. Yeti also claims it reduces weight by almost 300g compared to the regular version. This process results in strength where you need reinforcement, and lightness where you don’t.
With a 67.1-degree head tube angle, the SB5+ Turq is itching to bomb its way aggressively through steep rock gardens that leave little room for indecision while the short, snappy rear triangle tracks lines on a dime. Amplifying this bike's handling prowess, Boost rear spacing allows for stubby, quick-thinking chainstays that take successive bumps in stride while finessing a tough line.
Yeti’s Switch Infinity suspension is the lynchpin of the SB5+'s versatile capability. Its linear travel hits the sweet spot of anti-squat to keep pedaling sharp across rocky climbs, and it also erases the momentary harshness that its predecessor, the Switch Link design, would display when pushed to the absolute limit. Riding with the shock open won’t condemn you to bottomless squish when you have to transition quickly into a short climb on the other side of a long descent; the bike will still claw up anything without leaving you wide-eyed and white-knuckled when you fly down a deep rollover on the other side.
Other than those changes, long term Yeti fans will be relieved to learn that the suspension systems are fairly similar. Like the Switch Link, the Switch Infinity slider travels upward under the first phase of compression, when the SB5+ 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. Deep in the stroke, the slider works in conjunction with the upper pivot to produce a vertical wheel path that flattens big hits. On the trail, you'll be tempting faster lines across the chunky stuff as the SB5+ tidies up sloppy, questionable lines and sweeps rider errors under the rug.

- Familiarity: I've put it through the wringer
Yeti introduced there first plus bike, SB5+, last fall. Unlike some of its competitors, Yeti designed the SB 5+ around plus tires. Other manufactures designed there plus bikes to run 29ers as well as 27.5+. Yeti does not recommend running a 29er but I found that you can through on a 29 2.2. My first impression of the bikes design was it seemed a bit goofy with the elevated pivot point. Yeti’s Switch Infinity suspension platform and smart frame design will bring ease to a variety of trail conditions. The bike felt comfortable cornering, climbed remarkably well for a plus bike. Were it really excelled was on the descents. It was nible yet had amazing grip on those tight turns. Once the trail opened up I could just point the thing a fly downhill. I found that the Yeti felt lighter than most of its competitors. If you are looking for a plus size bike then look no further. Yeti has once again come out with a masterpiece in the plus class.
Feel free to hit me up with any questions regarding bikes:
Size Frame: What size frame should you go with?
Travel: Finding the right amount of travel that fits your riding style.
Full Package: Can provide a quote for both a custom or complete box build that fits your budget.
Comparison: How does this bike ride compared to others in the same class? What are the pros and cons of going with another option?
- Familiarity: I've used it several times
I was able to put the SB5+ through the paces for 3 days during a trip to Summit County, CO this fall. I've had the SB5 in the past, and presently have SB4.5 in the garage, so it's safe to say I'm a disciple of the Switch Infinity linkage suspension. The SB5+ follows in the same vein as the other bike of the SB lineup with incredible pedaling efficiency and power transfer paired with a supple, bottomless, feel once things get pointed downhill.
I didn't have a scale with me, I'd put the Yeti's claimed weight of 28lbs without pedals as being pretty accurate. My SB45 weights 26.5 with Enve wheels/pedals, and the SB5+ didn't feel much heavier in hand, or riding on the trail. The benefits of plus tires proved true, with confidence inspiring grip in loose conditions, and forgiving float over chunk rock gardens. I was tentative about flatting, so I ran what I felt was a higher than normal pressure of 15/16 PSI F/R for my 140lb frame, and had no punctures to speak of, so credit to the Maxxis Rekons there. My biggest day was a ride over the Ten Mile Range from Copper Mtn ski area into the town of Frisco. Going up, the plus tires had grip for days, and if I had the capacity to turn the pedals, the bike would have kept going, but damn did it get steep! Once on top, and coming down through the scree and roots and rocks, the SB5+ only inspired more and more confidence.
The last day I decided to experiment, and moved my 29" Enve M60 boost wheels onto the SB5+, clearance was a non-issue on both the rear triangle, and the 27.5+ Boost Fox fork (photo'd below). Ride wise the bikes geo wasn't adversely affected, and I didn't notice and difference in steering or feel. The most noticeable thing was the reduced wheel weight going from an alloy 27.5+ setup to a carbon 29" setup with 2.35 tires. I charged down the last part of the descent I had ridden the previous day on the 27.5+ wheels with the same confidence and speed. BB height on the stock SB5+ is on the lower end at 13", and I did notice more rock strikes initially, but never felt it was a constant problem. Overall I came away very impressed with the SB5+, I don't race regularly any longer, but still like a fast, capable bike. Should the occasional race pop up, I'd have no problem calling the 29" wheels into duty.
