SHIMANO TIAGRA 4700 Double Left Lever

The SHIMANO Tiagra 4700 left lever is just like the Japanese brand's mid-range groupset: simple yet incredibly effective.

Adopting a new ergonomic design closer to the top-of-the-range models, this lever guarantees more precise gear changes requiring less effort. Similarly, braking is smoother and more progressive, for enhanced comfort.
And, as an added bonus, they allow internal cable routing.
