F-Si Carbon Black Inc.

To create the fastest XC race rocket the world has ever seen, innovation is not an option, it's a necessity. Using our System Integration approach, every part of the new F-Si - from the asymmetrically offset rear triangle and drivetrain, to the new-school geometry and custom rake Lefty - was designed as a system, fully integrated in the pure pursuit of speed.
