The STI® lever incorporates an integral shift sensor that allows the computer to display not only the current gear selection but the gear ratio as well. The cycle computer also provides a display of pedal cadence in addition to the conventional speed, top speed, and elapsed time functions.
The mode select button on the STI lever lets you call up the desired function without taking your hands off the bars. You can also start the computer as you start your ride without changing hand position on the bar. The Flight Deck not only tells you how you're riding, it helps you ride better as well. It's a new milestone in user-friendly component design.
