Step onto your aerodynamic bike, place your arms on the bar-end and your hands on the new EPS™ controls. Snap into the pedals, and you're ready to challenge the clock. The new EPS™ controls are designed to keep your hands in the most aerodynamically efficient position at all times. With a simple click of the controls, the front or rear derailleur move quickly and precisely into the desired position without wasting a hundredth of second more than necessary, letting you focus every ounce of your energy on beating the clock or your opponents.
"Back to Zero position" system: allows the lever to maintain an optimal position with respect to airflow and allows for less effort for the athlete
SWITCH MODE BUTTON: the "mode" buttons allow the user to check battery charge, make fine adjustments to the rear or front derailleur - even in the middle of a race (with the "riding setting" procedure), and set the zero position of the rear and front derailleur ("zero setting" procedure)
Multi-Dome Tech™: these controls strike the perfect balance between operating force and tactile shift feedback, and also eliminate the possibility of unintentionally shifting the rear or front derailleur.
