Maximum efficiency for time trials with an aerodynamic design elaborated in the wind tunnel, respecting the weight since there are triathlons and mountain time trials. Side wind is no longer a problem thanks to the new aerodynamic design AIR PLUS U-Shape profile with a maximum width of 28mm. This allows the use of wide tires without negatively influencing the wind flow. Rim: Tubular AIR PLUS Carbon High modulus fiber with new formula High TG Epoxy more resistant to heat. B.S.T. braking band (basalt) Graphics with decor transfers on lacquer. Hub: NITRO Aluminum CNC Oversize straight pull. Spokes: SAPIM aero CX-RAY Closures: PG-404 Weight: Tubular Set 1.650g
