Details

Skip hibernation this year.

Extend the riding season and play in the snow like a kid again with the 2018 Borealis Bikes Flume NX/Bluto Complete Fat Bike. Not only is riding a new bike in the snow exhilarating, you'll stay fit over the winter months and have a leg up on your riding buddies come spring. This bike is such a hoot to ride that even after the snow melts, the Flume is plenty versatile and fun that you'll continue to pound out frequent miles on non-snow covered trails, bikepacking expeditions, or even a coastline tour.

The lightweight 6066-series aluminum frame is paired with a 100mm travel Rock Shox Bluto RL suspension fork so you can bomb down the sketchiest snow and ice covered singletrack with total confidence. The wide-range SRAM NX 1x drivetrain gives you plenty of gearing for tackling epic days in the snow-covered backcountry, loaded touring, or the burgeoning fat bike race scene. 4in rubber on 80mm rims gives you great flotation over the freshest powder and the geometry is honed from the experience that can only come from a company that specializes exclusively in crafting fat bikes. The frame's reduced stand over height is super helpful with the frequent mounting and dismounting that is expected with heavy boots and snow pants.

  • A no-nonsense fat bike for winter adventures
  • Fat bike specific geometry blend agility and stability
  • Aluminum frame is lightweight and responsive
  • SRAM NX group offers plenty of range
  • Colorado-based Borealis focuses solely on crafting fat bikes
  • Item #BOR000O

Unanswered Question

I was wondering if the wheelset is the tubeless ready FTD FR80 seen in the pictures, or the listed FR80? Also the tires listed are 45nrth and surly in the pictures?
