"The All-Rounder
From the rolling terrain in Okinawa to the KOM challenge in Taiwan, Racing Spec 4.2 has shown its limitless potential in the past few seasons. It is the ultimate all-rounder, ideal for handling all versatile racing conditions.
With its unique 45-mm deep rim shape, the 4.2 offers top-in-class aerodynamic efficiency and stability under cross-wind. Its 26 mm rim width is designed to equip wide tubeless tires at lower air pressure to maximize riding efficiency. Specially designed diamond-shaped aero blade spokes cut through the air in low drag. These spokes are stiff and light, enhancing rapid response. Â
Based on TORZC’s second-generation Ultra Smooth Carbon Fiber Moulding Technology, the wheelset is light in weight yet tough enough for daily use. The Racing Spec. 4.2 is ready to take on any opponents anywhere with you !
