Lighter. Faster. Better.
This is the next evolution of the bicycle wheel. And it is amazing.
There’s never been a wheel this incredibly light, this amazingly strong, and so aerodynamically slick—not in one single package—because there’s never been a wheel technology like ours.
We’ve replaced the traditional wheel—a structure comprised of dozens of individual parts like spokes, nipples, hub and rim—and reimagined it as a singular construct, a one-piece tensioned structure fused into a single cohesive unit.
Mad Fiber wheels give you everything. At 1,085g/pair, Mad Fibers are perfect for big climbs—but still provide full aero performance. And with 60mm front and 66mm rear aero rim profiles they are fast—but still climb and accelerate with the kick of ultralight wheels.
