Only a few words are needed to describe this bike...super light and super stiff. It is the epitome of a classic road bike. The Squoval 3 tubing has been redesigned, as well as the fork, which nets a 7.5 watt power savings. With a 9.5% stiffer bottom bracket compared to the last generation R5, this bike is perfect for acceleration, climbing or on the attack, while a 15% increase in torsional head tube stiffness offers improved handling. Tried and true Shimano Ultegra shifters, brakes and derailleurs, with an awesome Rotor 3D BBright crank with compact and pro chainrings, complete the drivetrain. Mavic Aksium S wheels and FSA cockpit. Super sick, light weight bike that is ready for touring or racing.
