SHIMANO TIAGRA 4700 Double Rim Brake Left Lever

The SHIMANO Tiagra 4700 left lever is just like the Groupesets mid-range: simple yet incredibly effective.

Adopting a new ergonomic design closer to that of 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.
