The long-travel 29er segment has moved to the forefront of the mountain bike market as riders discover how well the wagon wheels carry speed and roll over obstacles, preserving your hard-earned momentum both up and down the mountain. And with the continual push towards longer and slacker geometry, we've been impatiently waiting for Yeti's new crop of big-wheeled Super Bikes to hit the market. After much anticipation and speculation, the SB150 Carbon GX Eagle Complete Mountain Bike has hit our shelves, and it's markedly different than Yeti's previous long-travel 29er, the SB5. 5. Right off the bat you'll notice that the SB150 now has room for a water bottle in the front triangle, foregoing the mount on the underside of the down tube that subjected your bottle to mud, grime, and who knows what else. For those of us that ride without a pack and rely heavily on frame-mounted hydration, this is a huge plus. The SB150 also sees extremely progressive enduro geometry with a head tube angle approaching downhill bike territory at 64. 5-degrees, longer reach and wheelbase paired with a short 44mm offset fork, and a steep 77-degree seat tube angle that moves the rider weight forward for more control over the front end, as well as a better position for putting power to the pedals while accelerating up a climb. The chainstays are shortened to 17 inches to enhance cornering and provide quick power transfers for getting up over obstacles. In addition to these geometry changes, the suspension kinematics have also been revised for slightly more progressivity, and there's an extra 10mm of travel front and rear. This all adds up to a bike that's incredibly stable on descents, slaying steep enduro stages and chunky high-speed terrain with confidence-inspiring composure, all without losing the nimble handling and playful pop that make tamer trails more enjoyable to ride.At this point, it's hard to question the benefits of 29in wheels when riders are winning Enduro World Series races ...
