DOUBLE TAP
DoubleTap makes changing gears easier and faster, eliminating the cumbersome and awkward engagement associated with two- lever systems. DoubleTap handles up- and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars.

ERGODYNAMICS
Longer brake levers, independent reach adjust for the brake and shift levers, and optimized hood shape gives riders of any size comfort and easy access to the controls.

Reach Adjust 握距調整功能
煞車把手貼合度與主觀意識有強烈的關係。握距調整功能，可針對多種手掌尺寸個人化設計。Reach Adjust 可輕鬆調整你的手桿，為每個人提供最大的單指控制。

YAW
With a front derailleur cage that rotates to maintain a consistent angular relationship with the chain, Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.

ZERO LOSS
ZERO LOSS simply means, well, zero loss - when you push on the lever, for an upshift or down shift, the cable is engaged instantly - zero loss of movement. There is no middle- ground where you're waiting for the shift to come. Gear changes are instant and precise.
