“But that’s not REAL mountain biking!” …or is it?

Shops roll fat tired bikes onto their showroom floors to prepare for the onset of a long, snowy winter. Riders are shaking down their snow-specific rigs, checking to make sure they have all the gear they need to brave the cold, dark, wet trails of winter—and inevitably, adding more gear to their Christmas wishlists.
Some people have argued that fat biking isn’t even really mountain biking, or is almost another sport entirely. Of course, I disagree with that sentiment—I think fat biking is one of the most important revolutions in the sport of mountain biking, ever.
