Shimano's Sora Dual Control Levers offer smooth shifting and confident braking. The hoods are ergonomically contoured for a comfortable grip and easy access to shifting controls from any handlebar position. Top-view gear indicators ensure you know which gear you're in at all times.
SRAM's Force DoubleTap Control Levers offer a competitive advantage that allows you to shift from the hoods, drops, and even when sprinting. They're crafted with carbon and magnesium to create a system so light that it won't slow you down whether you're racing for prizes, bragging rights, or World Championships. The single-lever-shifting design allows for fast, smooth shifts and is completely independent of the brake levers, eliminating the possibility of braking when you shift. The front shifter uses Zero-Loss technology, instantly engaging the cable for precise gear changes. And both levers incorporate the popular reach adjust feature that allows you dial in exactly where your levers are in relation to your bars.
