A propulsive ride for pure speed When it came to creating the new Cielo X1, we kept our foot on the gas pedal and eliminated anything that didn’t enhance the ride. Designed with dynamic cutouts for weight savings, this ultra-fast road racer features a winged carbon fiber plate sandwiched between two layers of resilient PEBA foam. Sporting a speed-centric rocker shape, breathable knit upper, and gusseted knit tongue, you’ll be locked and loaded for racing.
