THE FLUME: Simply the best equipped aluminum Fat Bike on the market
Fatbiking adventurers know that inspiration matters, and a ride (or bike) is only as good as the idea that created it. The expedition-ready Flume capitalizes on all the sweetness of the Crestone, but does so in lightweight, 6000-series aluminum. Up mountains, down glaciers, and across deserts: the Flume is ready for action.
There are all kinds of alloy fat bikes on the market, but none with the Flume’s purebred heritage. The custom tubeset mates ideal, high-performance geometry with competition-ready spec. But if pedaling across our blue planet is more your speed, the Flume will speed you through.
-The Flume is built on an alloy frame that draws on all of our experience in making fat bikes at a much lower price.
-All aluminum frame with careful attention to finish details
-Borealis unique geometry for the best ride experience
-Available in two colorways
-Reduced stand over height
-Chainstay and seatstay protectors
-Rear axle and derailleur hanger
Frameset includes all of the above as well as:
-Complete headset and compression plug/ star nut
Based on our research, riders at the heights below will usually take the corresponding frame size. If you're at a transitional height that spans two sizes, look at the geometry chart to get the Stack and Reach you like based on other bikes you are comfortable on.
