Details

Since 2013, Borealis has specialized in lightweight carbon fiber fat bikes. The Crestone is their tried and true flagship model. Its frame geometry is optimized for riding in snow and sand with clearance for up to 5” wide tires. Paired with the most technically advanced components in the industry, the Crestone sets the standard for premium quality carbon fiber fat bikes.

Each Borealis Crestone is a custom build, the bikes we have in stock are in many configurations (color, drivetrain, wheels/tires, brakes, etc) and sizes.

Frame geometry provides responsive handling, offering maximum control for varying conditions in snow or sand.

Tire clearance up to 26x5” and 27.5x4.5”.

Compatibility for 100-120mm of suspension travel for more technical riding.

Lightweight, durable carbon fiber frame comes with internally routed cables, 2-3 bottle cage mounts and lizard skin protectors on both the down tube and drive-side chain stay.
