Typical Tiagra riders often place high importance on having a drive train and brakes that are dependable, consistent and require low maintenance. With the new Tiagra 4700 group set Shimano offers a great balance between performance, easy operation and low maintenance. 

The new rear derailleur has a revised cable pitch which offers precise and long-lasting shifting performance and is compatible with up to a 28T cassette. 
The SHIMANO TIAGRA rear derailleur shifts with a consistently smooth, light action. Designed for 10-speed road drivetrains, it is offered in short and medium cage options.
