2018 Stumpjumper Pro 29/6Fattie

Why should S-Works have all the fun? With our Stumpjumper Pro 29/6Fattie, you get many of the same performance features, like Öhlins front and rear suspension, so you can climb and descend with the best of them at the break-neck speed 29ers are known the world over for.

Starting at the carbon layup, it features our highest-end FACT 11m for an ultra-lightweight, strong, and stiff construction. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the all-new SWAT™ Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame. Further improving the ride, you'll also find an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, a slacked out front end, and our proprietary Rx Trail Tune at the shock. And to make things even better, the Stumpy's design also allows you the opportunity to toggle between 29-inch wheels and 6Fattie wheels (not included), allowing the ultimate in configuration options for the trail at hand.

And for this model, we outfitted the Pro with a high-performing build spec that features a SRAM X01 Eagle drivetrain, SRAM Guide RS brakes, Öhlins front and rear suspension, and hand-built Roval Traverse carbon wheels, so you get a bike that, without a doubt, is ready for anything on the trail.

The best of the best

I totally love this bike. I did extensive comparisons of this bike to many others on the market including other Specializeds, including the Camber and the new SJ and picked this as the winner for my type of trail riding. First and foremost, the full S-Works 11m FACT frame is incredible. Not only is it well made and looks great, the smooth ride that it produces has blown me away. The Ohlins suspension is also out of this world and is plushest, most comfortable suspension I have yet ridden on a mountain bike. No matter how rough the trail, the Ohlins tames it. In addition, adding to the smoothness of the frame and suspension are the awesome carbon 30mm Traverse wheels with the DT Swiss rear hub. The rolling resistance is nill on this bike even with the beefy Butcher and Purgatory tires. As for the rest of the components from the X01 drive train, carbon cranks and Guide RS brakes this is a killer package and I was lucky to get one of the remaining 2018s for a great deal. There's so much value in this bike that i couldnt pass it up! Finally I cant leave out the SWAT storage in the frame. What a useful thing to have on a mountain bike. Once you have SWAT in the frame, you will wonder how you lived without it. Ive had many many top end bikes over the years and this one is by far the best yet. Thank you Specialized!
