SET ROTI FULCRUM RACING ZERO CARBON C17 USB 28" Shimano HG

When this wheel came onto the market it marked a massive innovation in the field of low-profile wheels. What is innovative about the Racing Zero Carbon? The concept: carbon and aluminum blended together to form a unique combination. It has frequently been praised as “super stiff, sturdy and having razor-sharp precision", thanks to the aluminum spokes, and lightweight rim. The aim of Fulcrum's R&D department was clear and perhaps seen as a given: the character is not to be touched but the performance can be improved. The rim's standard measurements have stayed the same: 30 mm in height with a 17C groove that is a perfect fit for the 25 mm clincher tire. Twill carbon has been used plus AC3 technology for improved braking. The Racing Zero Carbon is an improved version of our classic Racing Zero.
