Echo

Named after Echo Canyon in Dinosaur National Monument up in the northwestern boonies of Colorado, the echo is the first performance-oriented, full carbon frame designed around the brand new RockShox BLUTO fat bike suspension fork. The extreme lateral stiffness combined with geometry optimized for the BLUTO’s 100mm of travel truly revolutionized fat biking. We also spec 35mm clamp stems and handlebars on our top two build kit models; this new oversized standard is a perfect match for the extra-wide tires of fat bikes. Internal dropper seatpost routing is the cherry on top of the echo’s design features that make it stand out as a do anything, ride anywhere, year round adventure shredding machine. See the full specs for each build kit below.

You’ll have to go ride one for yourself to find out just how much fun you’ll have. Check out our dealers page to find out where you can demo an echo.

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.
