Riders desiring hydraulic disc brakes on their road bikes can now get flat-mount discs from Shimano at a Tiagra price point. Previously, Shimano only offered this technology at Ultegra and 105 levels.
The BR-RS405 system uses 140 or 160 mm rotors with Shimano’s heat-dissipating ICE technology. Shifters feature 10 mm of reach adjust and will accommodate 10-speed cassettes.
Pricing has not yet been set. Aftermarket availability is predicted for July 2016.
