About Zipp 303 Firecrest Tubeless Carbon Disc Brake Rear Wheel

Zipp's 303 Firecrest Carbon Tubeless disc brake 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.
