Diamondback’s Sortie Black 29 is a premier machine ready to devour rock-strewn trails and ribbons of tacky singletrack alike. Your speed will hold fast as you power the feathery Diamondback aluminum frame over rough sections, letting the Knuckle Box linkage use its 5 inches of Fox Float Factory CTD suspension to deftly navigate whatever Mother Nature puts in your path. Crank Brothers' eye-catching Cobalt 29-inch wheels wrapped with WTB tires instantly hook up to the ground and inspire confidence as you steamroll roots, rocks and rubble. You'll love SRAM's class-leading XX1 drivetrain with XX brakes for World Cup level performance. The top-tier component spec continues with Crank Brothers Cobalt bars and stem combined with the Kronolog dropper post to ensure an insanely capable trail bike that's ready to charge.
