Have you ever been able to shift during an all-out sprint to the line or as you attack up a climb without slowing your pedal stroke? With Shimano Di2 electronic shifting, you finally can. Make the ultimate upgrade away from the limitations of cable shifting. Shimano boasts well over 1,000 miles before the battery ever needs to be charged. Plus, it only takes ninety minutes to charge!
The brake lever and shifter ergonomics feel perfect in your hands.
