Have it both ways! Our Borealis Flume bikes come dirt-ready with 27.5 X 3" plus tires and Bluto suspension forks. As a bonus, these are fully fat-compatible and ready for winter with the addition of a fatbike wheelset.
With premium frame quality and only the best components, the Borealis Flume offers the best value on the market. This expedition-ready MTB mirrors the Crestone geometry, 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 bikes on the market, but none with Flume’s purebred heritage and durability.
Traditional fatbike bike geometry is both responsive and nimble for variable conditions in snow or sand.
Standard features include Eagle NX 12-Speed drivetrain, Rock Shox Bluto Fat Bike Fork. carbon handlebars, carbon seat post and durable Velocity 27.5 rims with dirt-gripping Schwalbe Nobby Nic 3" tires. New Moon offers HED alloy and carbon fatbike wheelsets to upgrade a summer-ready Flume demo starting around $1700. Contact us for more info.
