With our new S-Works Enduro 29/6Fattie, some people asked us, "Why mess with a good thing?" But where some would comfortably rest on their laurels, we aimed to keep evolving. And the result is the most fun you'll ever have on a mountain bike. Seriously.

We gave it a geometry that features a slacker front end, a longer top tube, short chainstays, and a lower bottom bracket. All of this together makes the bike truly feel glued to the ground, and the platform is more responsive and capable then ever. We even added some bits, like integrated storage with a SWAT™ Door at the down tube, and made "old" new again by making a triumphant return to a threaded bottom bracket. To keep the weight down, the frame is constructed from our top-tier FACT IS-X 11m carbon fiber. And to ensure top-level performance on the descents, this material choice is greeted by 160mm of plush rear and 160mm front travel, plus a geometry that can be "adjusted" via a shock extension with a "low/high" setting.

And handling suspension duties out back is the revolutionary Öhlins single-tube rear shock. For the build, this Enduro spares no expense at hitting the pinnacle of performance, with a full SRAM XX1 Eagle 12-speed groupset, powerful Guide RSC Carbon brakes, hand-built carbon Roval wheels, and our Command Post IRcc Wu dropper post.

• The frame's FACT IS-X 11m carbon fiber construction stands as the pinnacle of lightweight, efficient, and tough trail performance. It's been built off our 29 Geometry in order to provide an aggressive, well-rounded ride. And with internal Command Post IR routing, a return to a threaded bottom bracket, and an integrated SWAT™ Door at the down tube, you get a bike that's clean, dependable, and ready for anything that the trail has to offer.

• Featuring a three-chamber air spring and TTX (Twin Tube) damping, the Öhlins RXF 36 fork perfectly mates stiffness with a plush, responsive ride quality, and stays smooth and high in the travel without compromising bump absorption, traction, or stability. It also features high-/low-speed and rebound adjustments, and sports 160mm of plush travel.

• The one-by drivetrain is controlled by SRAM's venerable XX1 Eagle components. The system forms the ultimate in efficiency and intuitive feel, while also having the added benefit of significant weight savings and minimal required maintenance.
