Orro Venturi STC SIG Ultegra Di2 is an excellent road bike for women. It has a carbon frame and fork, hydraulic disc brakes, and Shimano Ultegra drivetrain and shifters. The frame is made of carbon, which makes it lightweight and highly durable. The front end is aerodynamically optimized, and the finishing kit is made of carbon fiber for a smooth ride. The bike also has fully integrated cables that run through the bar and stem for a clean look. Plus, the coefficient of drag is reduced to help you go faster. The bike is easy to upgrade, so you can change the bar and stem if you want. It also comes with complimentary bike tools. The only downside is the price, which is quite high.
