Yes, it holds a water bottle. But there's much more to Yeti's new SB150 than the two appropriately placed bolt holes in its carbon frame. It's the most aggressive 29er that the Colorado-based company has ever released, with geometry numbers that place it on the cutting edge of the long and slack movement. The SB6 and its 27.5” wheels used to be the burliest machine in Yeti's lineup, but this new beast has taken the crown.
As the name suggests, there's 150mm of travel out back delivered by Yeti's unique Switch Infinity suspension design. Pair that with a reduced offset 170mm fork up front and you get a bike that's designed to take on pretty much any type of terrain imaginable, whether that's an Enduro World Series Race, laps in the bike park, or bashing around on your local trails.

There are five different build kits available, along with a frame only option, but even the GX Eagle base model will still leave a sizeable dent in your bank account – it's priced at $5,199 USD. The frame alone is priced at $3,800. For recent lottery winners, the top of the line XX1 Eagle option can be upgraded with DT Swiss XMC carbon wheels, putting the final price at $10,399. Frame Details
The SB150's carbon frame still has that distinctive Yeti look, thanks to its clean lines and the Switch Infinity suspension layout, but the downtube now straightens out a few inches before the bottom bracket, creating enough room to fit a water bottle, which is a welcome sight.
The shock is no longer attached directly to the swingarm, as it was in past models. Instead, there's a short aluminum link that sits just in front of the seat tube, with two curved links sandwiched inside it that are attached to the shock.
The shock is driven by a short link mounted just in front of the seat tube.
Yeti debuted their Switch Infinity system four years ago, so the basics should be familiar to many riders, but if you need a refresher, here it is: The system uses two short Kashima-coated rails (courtesy of Fox Shox, who collaborated with Yeti on the design) located just above the bottom bracket to manipulate the bike's axle path. Initially, as the bike goes through its travel the carrier moves upwards on the rails, giving the bike a rearward axle path for improved pedaling performance. As the rear wheel goes deeper into its travel, the mechanism moves downwards, reducing the amount of chain tension for better big hit absorption. Geometry
The SB150's geometry is what truly sets it apart from any of Yeti's previous offerings. It's slacker, with a 64.5-degree head angle, and longer, with a reach of 480mm for a size large. Tall riders haven't been overlooked either – the 505mm reach of the XL should fit riders up to 6'6” without any issues. In order to help keep the bike manageable while climbing, the seat angle sits at an appropriately steep 77-degrees.
Yeti also chose to spec the SB150 with a reduced offset fork (44mm instead of 51mm), which is becoming a common choice when it comes to this category of bike. How much handling difference the reduced offset truly makes is up for debate, but it does reduce the wheelbase slightly, and can add a little more stability at higher speeds.
