Description
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.
