The 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.

GEOMETRY & SIZING

Borealis offers four frame designs with unique fit and geometry to suit your every Fat Bike need. Begin by taking a rough size approximation on the chart below that is based on height, then select the corresponding bike with your fit needs by using the geometry chart further below. We recommend a similar fit to you mountain bike, so grab a measuring tape and dial it in.

RIDER HEIGHT RECOMMENDATIONS

Based on our research, riders at the heights below will usually take the corresponding frame size. If you’re at a transitional height that spans two sizes, look at the geometry chart to get the Stack and Reach you like based on other bikes you are comfortable on.

GEOMETRY CHART

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.
