Why We Like The SB150 Turq Mountain Bike Frame
If your ideal ride consists of point-and-shoot-style rock gardens on steep chunky trails that you pedaled yourself up to, then you'll need a capable and trustworthy steed between your legs like the Yeti SB150 Turq Mountain Bike Frame. Equipped with 150mm of plush Switch Infinity travel, slacked out enduro race geometry, and monster truck 29-inch wheels, the SB150 is a race bred machine that's designed to get you down the mountain as fast as humanly possible. That being said, the steep 77-degree seat tube angle and inherent efficiency of the Switch Infinity platform means this bike is no slouch on the climbs either, easily handling long transfer stages and big backcountry rides that require a lot of elevation gain. Compared to its shorter travel sibling the SB130, the SB150 is much more composed on steep technical trails, and it does a better job carrying speed in variable terrain than the longer travel SB165 thanks to the 29in wheels. So if going fast is your priority and you want a capable bike that won't hold you back, get in touch with one of our bike gearheads and get started with building up your dream bike.
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. Shortly after the SB150's release, Yeti pro Richie Rude piloted the SB150 to consecutive victories at EWS Ainsa and EWS Finale Ligure, solidifying the legitimacy of this new hard-hitter from Yeti and proving that the wagon wheels are here to stay. 29ers simply roll faster and don't get hung up as easily on obstacles, making them a stellar choice for covering ground quickly 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 bike.
The unmistakable Yeti ride quality comes from 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 head tube angle for better stability on descents and high speeds, all while maintaining excellent steering precision as the shorter fork offset keeps the wheelbase length in check. 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 Factory 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 in spite of its enduro-focused geometry, 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 for riders who prioritize the descent.
This frame 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 sure footed 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. Also, it's worth noting that the rear triangle has clearance for up to 2.5in rubber, letting you run high-volume rear tires if desired.
