Shimano's Di2 electronic gear shift system enables riders to shift gears with electronic shifters rather than conventional control levers. This system permits gear shifts that are faster than a mechanical system. Di2 is not affected by stretched or worn cables and the smoothness of electronic shifts can reduce shock on drivetrain components. It allows for an accurate and effortless shift.

Yes, I recommend this product.
The bike is fantastic, fast and aerodynamics. I am very pleased with the purchase. I recommend everyone TMR01. I have only one problem, the seatpost saddle has come down when you step on a few holes, even making the adjustment with a torque wrench.
