Zipp: PROPULSION IS POSSIBLE The Super-9 gives you the technology needed to do your best. Pro-proven, the Super-9 Tubular Disc brake wheel optimizes supreme aerodynamics, power transfer, stiffness, lightweight and durability. The Super-9 remains flat from its widest point all the way to the hub. This relatively simple-looking shape results in a wheel that’s fast and stiff. Add to that the modulation and stopping power of disc brakes, and you’re ready to attack the tri or time trial course.FEATURESNew Zipp graphics and cosmetic identity that screams speed applied with our ImPress direct-print technologyGreater stopping power and modulation of disc brakesAero, durable, light weightCenter locking rotor interface.
