Shimano Tiagra ST-4720 Hydraulic Mechanical STI/4770 Flat Mount Calipers

The biggest innovation within the Tiagra group is undoubtedly the introduction of a group-integrated hydraulic disc brake system with new BR-4770 flat-mount calipers.

The new ergonomic dual-control shift/brake levers (ST-4720). For even more customisation options, the Tiagra Group offers an additional STI model (ST-4725), which has been specially designed for drivers with small hands by changing the angle to the handlebars and outwards.
