On Monday, De Rosa announced the DeRosa 70, a lightweight aero bike. The company says that since the headset tube has no edges, the bike has no interference with aerodynamic flow. The name is a reference to 70th anniversary of the company’s founding by Ugo De Rosa. The legendary frame builder died in March.
The top tube slopes slightly and has a hexagonal shape, adding to its aero features. The bike was designed by Pininfarina, the Italian car design company and took 22 months to create. The frame comes in at 730 g, but is still stiff and responsive.
According to De Rosa, its the company’s most advanced frame to date.
