SB150 Turq X01 Eagle Complete Mountain Bike
Seeing 29ers across the industry adopt slacker geometry and move to shorter 44mm offset forks, along with the release of the SB100 and its updated Switch Infinity design, we figured Yeti had some new big-wheeled bikes in the works. Well, the SB150 is finally here, and it's the burliest wagon wheeler yet from the Golden, CO based company. Six inches of plush travel afforded by the reconfigured Switch Infinity platform now allows room for a water bottle in the front triangle, solving an issue that has had critics nitpicking Yeti for years. But that's just one change of many that differentiate this bike from its predecessor, the SB5.5. Progressive geometry pushes the envelope with the head tube angle approaching downhill bike territory at 64.5-degrees, a longer wheelbase and reach, and a steep 77-degree seat tube angle to keep things pedal-friendly. The chainstays are shortened to a stubby 17 inches, quite a change for Yeti who has long held to more traditional chainstay lengths. The suspension kinematics have also been revised for slightly more progressivity, and there's an extra 10mm of travel front and rear. These changes all contribute to a ride that's incredibly stable when the trail gets rough and steep, without sacrificing the nimble handling and playful pop we enjoy on tighter trails. This bike, the SB150 Turq X01 Eagle Complete Mountain Bike, doesn't leave much to be desired with its top-level TURQ carbon frame, Fox Factory suspension, and SRAM's XO1 group checking all the boxes for the ever-increasing capabilities demanding by riders.
At this point, it's hard to question the benefits of 29in wheels when riders are winning Enduro World Series races and World Cup Downhills on them. Yeti's own Richie Rude piloted the SB150 to a stunning victory on the steep and loose stages of the EWS at Ainsa, immediately followed by another win at EWS Finale Ligure, solidifying the legitimacy of this new hard-hitter from Yeti and proving that the wagon wheels are here to stay. The fact is, 29ers just roll faster and don't get hung up as easily on obstacles, making them a stellar choice for quickly covering ground on rugged terrain. Of course, all of this was brought about by changes in modern geometry, boost spacing, better suspension, and refined frame materials—all things that Yeti took full advantage of with this new bike.
The unmistakable Yeti ride quality is attributed to their Switch Infinity suspension design. Honestly, Switch Infinity is some of the best we've ridden. It's plush throughout the 6 inches of rear travel, delivering a smooth ride quality that feels like you've got more travel than the numbers show, while maintaining impressive traction across chattery small bumps and square-edged hits alike. The key to its performance is the translating main pivot, aka the Switch Infinity link, which switches direction as the bike moves through its travel, providing excellent anti-squat characteristics for superior pedaling performance, and ideal suspension characteristics as it gets deeper into the travel. For the SB150, Yeti made the leverage ratio more progressive to provide greater compatibility with modern shocks and various rider weights and styles. The refined leverage ratio also gives the bike better small-bump compliance, quicker ramp-up in the midstroke for a more playful and supportive feel, and better bottom-out control while still allowing full travel usage. The SB150 is also the first to employ the patent-pending wishbone shock extender, which maximizes standover height and allows Yeti to fit a water bottle inside the front triangle, all while maintaining compatibility with a coil shock.
On paper, the long, low, and slack geometry with plenty of suspension travel make the SB150 look like a wicked descender, and that it is. By using a 44mm shorter offset fork, Yeti was able to seriously slacken the real head angle for better stability on descents and high speeds, all while maintaining excellent steering precision. The longer reach, steeper seat tube angle, and short chainstays help move the rider forward on the bike, keeping weight on the front wheel for better traction on steep chutes and chunky downhills. Paired with a metric Float X2 rear shock, this bike absolutely rips on the descents.
These geometry benefits are not one-sided though, as the steeper seat angle, short-offset fork, and forward riding position help keep power to the pedals and the steering quick and nimble when climbing. Frankly, we were quite surprised with how well this bike goes uphill, clamoring up the loosest, steepest, and most ledgy terrain we could find with relative ease, enough to convince us the SB150 is worthy of being a one-bike quiver.
This model uses Yeti's TURQ Series carbon fiber, consisting of the highest quality materials Yeti can get their hands on, delivering a fine balance of strength, low weight, stiffness, and compliance. This makes for a ride that's fully composed over rough terrain, and surefooted when you're stepping on the gas and railing high-speed corners. By using high-modulus carbon fiber, Yeti is able to shed roughly 250 grams from the Carbon series frames while maintaining the same levels of durability. They were also able to incorporate full-length tunnels for the cable routing, giving you a rattle-free ride and simplifying maintenance since it's so easy to feed your cables through the frame. The frame is tested to DH standards, well beyond what most others do for a 150mm trail bike. It has to be strong enough for a tank like Richie Rude, who makes the earth shudder underneath him while riding, so it's certainly tough enough for the rest of us. Yeti is so confident in their carbon that they are now offering a lifetime warranty on the frame, just for good measure.
As mentioned above, the build kit on this bike is everything we'd want without completely breaking the bank. Top-tier Fox Factory suspension with low-friction Kashima coating yields a plush ride, with a good range of adjustments to dial it in for your individual weight, riding style, and the terrain at hand so you can charge the hardest lines with confidence. When you need to arrest that momentum, XT 4-piston brakes do the job nicely with plenty of outright power and improved modulation. Acceleration duties are handled by a SRAM XO1 drivetrain that offers precise, reliable shifting with a wide gear range and a 50t bailout gear that helps you crest the steepest climbs. It's worth noting that the frame has clearance for modern 2.5in rubber, despite coming stock with a 2.3 in the rear.

Yeti get's it right! I've rode a few before and although I have always been a fan of the SI link for some reason I haven't just jived with the bikes. The SB5c when it came out although light playful, to me nervous twitchy. I was all excited for the SB6 and a great climber but I felt it lacked confidence in the front to really rally the the turns unless a berm was involved. To say the least I was excited and a bit apprehensive when jumping on the SB150. I also don't put much stock in the Geo numbers anymore I simply want to ride it and see if it works......
So I picked it up the SB150 strapped on the Shockwiz and proceeded to hit the rough and rowdy trails that I consider the norm. I'm a long travel kind of guy and if it isn't at least 160 up front meh someone else can ride it.
This fits the bill and doesn't under deliver at all. Handles the rough, rolls in the smooth and climbs really well for a LT bike which is all what you have heard before. Ok, so on to the stuff most won't say. Seat tube angle great, it's super steep and for the really steep climbs it's awesome but for the rest of the day I feel it kind of sucks. I feel that it positions me way to far over the cranks even with the seat slid all the way back, which when pedaling puts more of an emphasis on legs and doesn't engage the glutes which can wear you out a bit sooner. However it will climb a brick wall if you can get the traction. My only other gripe is that I feel it lacks a small amount of mechanical type grip in the flat corners. It rolls in with a lot of speed, turns in beautifully and then the front starts to slide and push. It's transparent and you can feel it loose traction and it will cause you to shift a little body weight over the bars when it happens which is easy to over come and rally on, but I think something is missing. (Disclaimer here: this is being really really nitpicking)
Great climbing LT 29er

smooth suspension and light feeling bike
Aggressor tire is for trail riding not Enduro
I would like more room to strap tubes, tools etc on frame
Like to see some rubber grommets or sleeves on the cable ports
