Zipp 303 Firecrest Carbon Road Wheels (Black) (Shimano HG 11/12) (Rear) (700c) (Centerlock) (Tubeless)

Zipp 303 Firecrest wheels were designed to make you faster. Zipp focused on making the wheels as efficient as possible because efficiency=speed. Zipp made the 303 Firecrest wheels more efficient by creating a wider and shallower rim profile. It allowed for wider tires to reduce rolling resistance, it helped reduce weight, and the bulbous design proved to be more aerodynamic.

• Optimized for wider 28mm tires
• Wide 25mm internal width
• The ZR1 DB hub has 66 points of engagement for a quicker response
• Hookless rims require hookless tires and max tire pressure of 73 PSI
