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.
