Shimano Tiagra has long been a stalwart of the Shimano line. Functional, dependable, and incredibly durable, it was a groupset that cared more about getting the job done that about looks and having the latest tech. Well...that's all gone and changed. At least the looks and latest tech parts. Tiagra stays at 10-speed, but Shimano has completely redesigned the 4700 Tiagra groupset to give you the looks and technology found in the company's 11-speed groupsets, while maintaining the same attention to value, intuitive functionality, dependability and durability.
The all-new Tiagra BR-4700 rear brake is a worthy upgrade to its successor thanks to a new one-thrust pivot bearing that reduces overall caliper friction, and a linear braking operation that produces 30% more braking power and easier modulation. The new brakes also provide an all-new adjustable toe-in brake shoe that makes dialing in your brakes for optimal performance a breeze. These powerful dual-pivot brakes are designed to work perfectly with the new Tiagra 4700 levers (50-4322) for the best in total control.
