We'll cut to the chase the difference between the regular X01 SB6 and this one is the wheels. ENVE M70 wheels stand in for the stock DTs, and they're laced to DT Swiss 240 hubs. You've probably read about Switch Infinity, or at least seen the strange looking mini stanchions, and you may have even heard that, lo and behold, those little things actually work. . The SB6 Carbon is in that small class of long travel trail bikes that is truly capable of being pedaled all day long, largely due to the Switch Infinity platform. The first thing you'll notice about the SB6C are the unconventional pivots, and the tiny bit of Kashima coated, Fox branded bits at the bottom. Don't let the color and Fox brand fool you, though, these little stanchions aren't shocks. Rather, they're much more closely related to the rail system used in Yeti's downhill bikes, most recently the 303. They're there to provide a linear spring rate, which, among other things, minimizes the felt impact of big bumps when you're deep in the travel. To complement all of that engineering, we've outfitted the SB6 with choice components from Fox, SRAM, Shimano, and Easton. The 1x11 X01 group takes care of drivetrain duties, and stopping is handled by Shimano's excellent XT brakes matched up to 180mm Ice Tech rotors. A Thomson Covert dropper post supports the WTB saddle, FOX's FLOAT 36 and FLOAT X fork and shock take care of the squishy bits, and traction is provided by Maxxis' 27. 5 inch High Roller tires.
