A glance is enough to perceive the first novelty of the Speed ​​CMPTZN DB wheels. In fact, the new models share the Black Label graphics Already adopted for the Racing Zero CMPTZN family.
The real challenge was to improve the superlative FULCRUM Speed ​​55 dB with which the Speed ​​CMPTZN DB wheels share some technical details, such as the Full Carbon circle with "Twill" finish and the Raggiaura 2: 1. This time we wanted to optimize a high -end product by offering one further step in terms of smoothness and lightness.
We therefore entrusted to the refined technology of our Cult ™ bearings which allow you to save weight (10 grams less than the Speed ​​55 dB) and to reach a smoothness of up to 9 times more than traditional solutions with saving up to 3.5 watts in pedaling. mechanics, the new hubs of the Speed ​​CMPTZN DB wheels also boast a Aesthetic restyling and show off a Matt Black look In perfect balance with black graphics on black of the circle.
The new models are available in the version 2-Way Fit which allows to mount both tubeless (for better smoothness and resistance to drilling) and coverings (for the more traditionalists).
