Shift/Brake Set Shimano Tiagra ST-4720/BR-4770 Left, 2-speed

The Shimano TIAGRA ST-4720 + BR-4770 is a left-hand 2-speed Dual Control shift and hydraulic disc brake set designed for 2x10 road drivetrains. It combines an ergonomic STI lever with a powerful flat-mount brake caliper, delivering improved control and confident braking in all riding conditions.

One of the biggest updates in the Tiagra series is the introduction of hydraulic disc brakes with the BR-4770 caliper. The redesigned, slimmer levers provide enhanced grip and reduced lever travel. The one-way bleeding system makes maintenance quick and simple. The result is consistent braking performance and smooth front shifting for road and cyclocross applications.
