The URSA Major sets a new standard for steel fatbikes with its ultra short 435mm chainstays, 197 thru axle stainless sliding dropouts and class leading standover clearance. Designed for compatibility with either a rigid 483 axle to crown for or a Bluto 80/100mm suspension fork. The URSA Major has been snow raced and tested in Utah, Idaho, Wyoming, and Colorado and on the dirt in Colorado and throughout Texas. We've lowered the top tube on all sizes to give the best in class standover height. When you standover your bike in the snow you'll thank us. MADE IN USA.
