Shimano's new TIAGRA group set gives grassroots & new road cyclists the opportunity to ride a group set inspired by professional riders, whether for challenging sportives, everyday commutes or long weekend rides. For the first time in its history TIAGRA supports internal cable routing, which gives the road bike a much more clean & professional look. Along with internal cable routing TIAGRA has also adopted the iconic four-arm crank design. The new TIAGRA shifting platform provides virtually effortless & accurate shifting operation. TIAGRA 4700 runs on a 10-speed drivetrain operated by enhanced ergonomic shift/brake levers (STI). The slim & compact bracket grip offers easy reach to the brake/shift lever from the hood position & a comfortable lever feeling for a wide range of riders. With the new TIAGRA 4700 group set Shimano offers a great balance between performance, easy operation & low maintenance. The new rear derailleur has a revised cable pitch which offers precise & long-lasting shifting performance. Meanwhile the new TIAGRA brake system offers consistent all-round control in all conditions. Compared to the previous generation the braking power has increased by 30%, while the modulation of the brakes has enhanced too.
