2018 Specialized SJ Expert 11m 27.5

Everybody loves carbon, and with this in mind, we took our budget-friendly, but no compromises, build of our Stumpjumper Expert, and paired it with an all-carbon, 11m frame. Add in our Fattie Wheel/Tire System, with its drastic increase in traction, control, and flotation, and you have the ultimate trail bike, all while keeping some extra jingle-jangle in your pocket.

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.

Then there's our 6Fattie Wheel/Tire System that takes 650b wheels and wraps them in 27.5x3.0" tires to provide a drastic, life-changing level of traction, control, and floatation. Impressively, 6Fattie pulls this off without sacrificing anything to climbing prowess. This system also allows you the opportunity to toggle between 29-inch wheels (not included) and 6Fattie wheels, allowing the ultimate in configuration options for the trail at hand. 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 when you factor in a build spec that has some of SRAM's best performing and durable components, you have a bike that will have you never looking back—unless it's to see your buddies eating your dust.
