Borealis Echo X01

Borealis Echo X01


Seen here with X01 livery and 45NRTH Husker Du tires, the Borealis Echo starts to look less like “just a fat bike” and a lot more like a mountain bike. SRAM’s unflappable one-by drivetrain, hydraulic disc brakes, and a real-deal suspension fork from RockShox round out the Echo’s already-capable carbon fiber frame. Borealis believes that fat bikes are meant to be ridden anywhere and everywhere, and when we see them built like this, we’re inclined to agree. It’s nearly as efficient as your favorite hardtail, but with heaps more traction and confidence over rough trails and chunky downhills. At the heart of the Echo is the 197mm rear spacing and 135mm front spacing that allow for super-strong, dishless wheels.
