"After one ride on the all-new Stumpjumper FSR Expert Carbon 6Fattie, you'll never be riding trail again. It's a bold statement to make, but the increase in traction, control, and floatation that our 6Fattie Wheel System provides is nothing short of revolutionary. And then, of course, there's the rest of the bike. It features our FACT 9m carbon fiber for the bulk of the construction in order to provide an ultra-lightweight, strong, and stiff frame. 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. And when you factor in a build spec that mixes some of SRAM and Shimano's best performing, durable components, you have a bike that will have you never looking back—unless it's to see your buddies eating your dust."
"Jumping off the S-Works 29er onto the S-Works 650B the trails felt very different to ride indeed, not so much easier or faster, we were just able to 'let it hang out' a bit more and that's more our style."
"I'll admit that while interested in plus size tires and bikes, I was a little hesitant to hop on one while out in Graeagle, CA. Here we were starting around 6K feet of elevation and I'm about to ride with a bunch of super fast riders including Ned Overend and they hand me a 6Fattie? OK, then. Honestly though, after we started climbing out of camp towards the summit of Mills Peak there wasn't one point in which I even thought to myself about wishing I was riding something else. The big tires climbed much better than they should, no doubt helped by the carbon rims."
"Overall, I think the new Stumpjumper 650b is an absolute winner. Stiffness and response is as good if not better than my 26", it pedals better than my 26" and the cornering traction and rollover ability is nice improvement and it jumps just as well and the 26". The only real down side is it is slower to accelerate and take a little more effort on slow climbs, but something nice carbon wheels might narrow the gap. To me the bike is an ideal replacement for the 26" SJ Evo, and I'll be ordering one up real soon!"
