Every year bikes get lighter, skinnier, and more efficient, giving you less, and less, and less. Specialized took a different approach with the Fuse Expert 6Fattie and gave you more. More traction, more flotation, and more laid-back fun. Rolling on 650B x 3.0-inch tires, the Fuse Expert delivers unprecedented traction and stability so you can shred the loosest, most off-camber and rock-strewn trails you can find. The solid M4 aluminum frame features Specialized's exclusive Diamond Stay technology to accommodate 6Fattie wheels and tires while maintaining the short chainstays that keep a bike playful and fun. The spec is dialed with a RockShox Reba RL fork, Specialized Stout wheels, and a 1 x 11-speed SRAM GX drivetrain with a wide-ranging cassette. There's even a dropper post for maximum control when things get rowdy. Get on a Fuse and find out what you've been missing.
