There's a fine line between tickling the ragged edge and cartwheeling through the weeds. Thanks to Specialized's Stumpjumper FSR Carbon 6Fattie, that line is going to be a little bit wider. Built to fit plus-size 650B x 3.0inch tires on 30mm wide wheels, you'll experience a mind-bending level of traction and control up, down, and in the twisties. But it's not all just about wide rims and fat tires. A FACT 9m Carbon frame, dialed geometry and 135mm of travel make this Stumpy an absolute riot to ride agressively. And, Specialized's innovative SWAT Door in the down tube has plenty of room to store some tools, a tube and a pump, so it's always ready to go. Finished out with a Specialized Command Post IRcc dropper, this Stumpy 6fattie is eager to get rowdy yet keep you on the right side of that fine line.
