Editor’s Note: Along with longtime Mtbr forum member Kent Robertson (KRob), the 2016 Outerbike Test Sessions were conducted by Ben Slabaugh, aka Schlim on Mtbr. Ben, 37, has been riding mountain bikes since he was 12, and today leans toward the XC side of things. This year, the pair headed to Moab, Utah, for the annual Outerbike consumer demo event where they rode as many bikes as possible. These posts are first ride impressions only — not full reviews. However, they stand by their opinions, and feel like they are good at feeling out the true identity, strengths, weaknesses, and soul of any given bike. For each session, they attempted to get set-up and suspension as dialed as possible. Test rides usually lasted 30-60 minutes. All bikes were then rated on a scale of 1-5 for visual impression/looks, climbing ability, descending, cornering, general agility, fit, and an intangible factor. Lowest possible score is 7. Highest is 35.

My upfront admission is that the Yeti SB5+ was my favorite bike at Outerbike this year. It’s a dedicated 27.5 plus semi-fat setup with 127mm of travel rear and a 150mm boost fork up front. As fate would have it, we had to wait out a rainstorm on Sunday afternoon before heading out on our last run. The rain made the desert dirt a little more tacky and took down the dust very effectively to showcase the all around benefits of big traction on the Bar M trails.

Not everyone will love the elevated chainstay, but it was a necessary evil to get this bike to work.

The tech who set up the bike told me that the SB5+ frame might be able to fit a 29×2.2” wheel-tire combo, but standing it up against a Yeti SB4.5, there is a visible 1” difference between the tire diameters, with the 4.5 being the taller of the two. According to my un-scientific observation, 29er hoops would definitely raise the bottom bracket and likely change the handling. The SB5+ front triangle is a different carbon mold than the SB5 or the 4.5, so Yeti has a considerable investment in it.

For 2017, it looks like Yeti is going to Ergon saddles, which other brands featured at Outerbike as well. The Ergon isn’t bad, it just isn’t great for my own backside compared to a WTB Volt, Devo, or Silverado. Also, to get the obvious out of the way, the elevated chainstay looks inorganic and not really in keeping with the flowing lines of the current Yeti line. It does, however, provide clearance, and the single-piece bracing at the bottom looks stout as heck. And onboard you don’t see the rear triangle; the feel and experience is all Yeti.

Out on the trail, the SB5+ felt comfortable and sure-footed like you might expect a plus bike to ride. It was downright capable and damned playful in temperament. The rear axle is boost 148 spacing, which should assist in minimizing flex and keeping things snappy. But I did not expect a plus bike to ride like this one did. Every lip and rise in the trail felt like a launch pad. Every step down was a chance to fling the Yeti into the air.

My measure for an extraordinary bike is always to ask, does it make me a better rider than I think I am? Like maybe one other bike I rode this weekend, this one does. Riding along behind me, Justin said my own riding technique looked better on the SB5+ than the other bikes I tested. One telling trait was that I was willing to hang onto bad lines on the Yeti and just give it a few more seconds to crank it out before giving up and bailing out because I trusted the grip and handling to give me an edge.

The Maxxis Rekon is a beast of a tire, and at 2.8” you didn’t feel the need for a wider 3.0” option.

The scrambling score, for lack of a better descriptor, was top-notch. The long front-center of the bike assisted in the stability to hit successive drops and navigate technical chunk with velocity. I was looking out specifically for the switch infinity suspension to hang up on square-edged hits and step-ups like the SB95 with the switch link eccentric did, but I never felt that hiccup in motion.

I was also a fan of the overall build choices on the SB5+. The Maxxis Rekon is a beast of a tire, and at 2.8” I didn’t feel the need for a wider 3.0” option (although the frame would accommodate it without a problem). As with the other Shimano-equipped rigs, this one felt more precise and refined than the SRAM drivetrains, and my own choice of build right now would be Shimano.

Another marked improvement over a couple of years ago is the Fox Float 34 fork. This run of 34s is right there in terms of feel with the smooth off the top action of RockShox Pike and Revelation forks when left at full open. It pretty much operates invisibly when set up correctly. I didn’t get any wrist zinging like I did from other bikes with narrower tires and alloy bars, and I didn’t have to put it in the trail setting to keep it from diving. The whole experience was very seamless in a way I rarely experience from demo bikes.

Plenty of clearance at the rear if you want to go wider.

As I mentioned in my Pivot Firebird review, I bought a Yeti SB4.5 29er this year. Yeti totally sucks for coming out with something that is probably better than the 4.5 so soon. I’ve been raving about that bike since March and how it is the best all around bike I have owned or ridden, but it would be an extremely hard choice between the SB4.5 and SB5+ if I had to buy again right now and could only have one. With the SB5+ you can lean and lean and lean without breaking loose. Over a multi-hour ride you’d feel the extra weight, but I think 80-90% of riders could use this as their primary go-to mountain bike. It has oomph and braaap, and yeehaw all built in.

Outerbike Test Session Score: 33 out of 35

    Cool review. I’m left wondering if overall I’d be a faster rider on a well dialed plus bike like the SB5+ or something more Enduro focused like the SB5.5 w/ 2.5 tires installed?

  • WasatchEnduro says:

    For beast trails the 5.5 is the way to go. The 5+ seems like a better bike for a lot of “trail riders”. No way can the 5+ touch the 5.5 for proper all mountain riding.

  • Mark Sevenoff says:

    Been on a S-works 29 Enduro for the last 2 years, before trading it in on a 150mm front/135mm rear Stumpy 6 fattie. Nearly all my DH times are faster on the plus bike here in Moab including taking 10 minutes off my Whole Enchilada time from last year. (proof) = https://www.strava.com/activities/764865618
    #plusCANbefaster – as long as you can keep air in the tires 🙂

    I hate FS bikes. I don’t know why, but I could never climb up any technical trails with any FS bike. That was until I rode a SB5+ two weekends ago under the wettest conditions in one of the most rocky and technically challenging parks in my area. Boy, was I blown AWAY by how this thing climbs over slippery rocks! Not specifically the traction (which I expected since I have a Trek Stache 9 with 3.0 Chuppas), but the fact that the suspension did not hang me up while climbing! It climbed as well as ANY HT I have every ridden before. And off course, on the ‘plus’ side, now I could descend with abandon! HT’s are a compromise, but since I could never climb with a FS, I accepted it. I always enjoyed climbing more than descending. Now I can enjoy BOTH. I want to ride the other Yeti’s with the Switch Infinity suspension system (non-plus 29er and 27.5), but I feel the grip on the plus tires will be so much more helpful in the wet conditions on the rocky East Coast. Either way, the switch infinity suspension is magic and I can’t wait to get my hands on one of these.

      Agreed. I’ve been riding all-mountain hardtails exclusively the last couple years, in large part because I never found a FS bike that climbed like I wanted it to. I demo’d a SB5+ for a couple days and was blown away. I’d never been on a bike with that much smooth travel, that could also climb the way it did. And it is hands-down the most playful plus bike I’ve ever ridden. As the author states, this bike just wants to pop off everything, with butter smooth landing manners every time.
