The Fat Bike Company, better known as the people behind Colorado-based Borealis, is on a roll. The company recently completed a move into a new spacious 11,000 square foot facility in Colorado Springs, which will support its expanding in-house engineering, production, and sales departments. It also has a host of new products that it was showing off at last week’s Interbike trade show in Las Vegas. Here’s what you need to know.

Borealis Crestone Frame

The Crestone is a new “state-of-the-art” carbon fiber fat bike frame that continues to “demonstrate Borealis’ commitment to providing fat bike enthusiasts with the industry’s most cutting edge equipment to ensure they have the very best carbon fiber fat bikes available,” said Steve Kaczmarek, company Founder and CEO.

Borealis says it challenged staffers to utilize an entirely new computer generated design process, which helped reduce waste in manufacturing along with reduction of the frame’s weight. The development team took months to test the frame and invested countless hours to ensure they got the geometry just right.

The bike is touted as being 150 grams lighter than Echo, Borealis' first carbon framed fat bike.
