Description

There are places in this world ordinary bikes can’t take you. And when every ounce counts, when every pedal stroke drives you further into the wild, get there on the Borealis Crestone. The lightest and toughest carbon fat bike on the market lets you follow northern lights deep into a Wisconsin winter as part of the 42K Solstice Chase, or pack it up for a blitz across the tundra – the Crestone is the premier choice for fat biking fun.

As fat biking differentiates itself, carbon rigs are a way to outdistance your fellow riders – both at the trailhead and when deep in the bush where no trails exist. The Crestone is the elite choice.

Stack and Reach are the fundamental fit elements, they are both measured relative to the bottom bracket. When choosing the Borealis that is right for you, it’s important to find a balance in these measurements to ensure the best performance.
