Catlike is a continuously evolving brand that needs to adapt to the rapidly changing market. The new trends in the various cycling disciplines are generating new needs in terms of materials and components for athletes. CHORNO was created to cover the range of specific products for short time trials and triathlon competitions, where a very aerodynamic and versatile helmet is necessary, for this reason it is a hybrid solution between the old time trial helmets and road cycling helmets. Our experience of more than 10 years working together withCatlike, professional cyclists and wind tunnel laboratories led to the rapid development of the CHRONO model.
