Ultimate Shimano TT Groupset redesigned hydraulic disc brakes balance speed control and stopping power like never before. DURA-ACE brakes feature easier maintenance as well as better modulation and control. The new brake calipers offer increased pad-to-rotor clearance when the brake is disengaged, lessening the likelihood of rotor rub even if a rotor is slightly out of true.
