Shift/Brake Set Shimano Tiagra ST-4720/BR-4770 Right, 10-speed

The Shimano TIAGRA ST-4720 + BR-4770 is a right-hand 10-speed Dual Control shift and hydraulic disc brake set designed for 2x10 road drivetrains. It delivers improved ergonomics, confident braking power and smooth rear shifting for road and cyclocross bikes.

The redesigned, slimmer STI lever provides a more comfortable grip and reduced lever travel. Paired with the BR-4770 flat-mount caliper, the system offers stable and well-modulated braking performance in all conditions. The one-way bleeding system simplifies maintenance, while Shimano mineral oil ensures consistent and reliable operation.
