Not many bikes can match the F2 SL’s extraordinary blend of light weight, stiffness, strength and forward-thinking technology. It’s the balance of all these traits—achieved through meticulous engineering and superior Ultra High Modulus carbon fiber materials—that sets the F2 SL apart. And the performance of the precision frame and fork is even further enhanced by Shimano’s revolutionary Dura-Ace Di2 electronic shifting.
