It's a fine line between in-control and tickling the ragged edge. But, thanks to Specialized's Stumpjumper FSR Expert 6Fattie, that line got a little bit wider. Rolling on beefy Specialized 650B x 3.0-inch tires that are mounted to 29mm-wide rims, you'll experience a higher level of traction and control. But it's not all about fat tires; the FACT Carbon frame, dialed geometry, and 135mm of travel make this Stumpy an absolute riot to ride. And, Specialized's innovative SWAT door in the downtube has plenty of room to store some tools, a tube, and a pump so that you're always ready to go. The Expert is packed with excellent components, like a plush 150mm-travel Fox fork and a 750mm-wide handlebar. There's also a SRAM X01/X1 1 x 11-speed drivetrain and carbon crank to put the power down. Finished out with a Specialized Command Post IRcc dropper, this 6fattie is ready to devour some singletrack.
