TRP TT HD-T910 is the all-new performance Time Trial Road Bike hydraulic disc brake. TRP took a unique approach to the time trial brake, by combining speed and style, resulting in the TT Hydro. Initially, the lever was handcrafted from clay, before finally being remade in aluminium, using the shape of the clay mould. This allowed their designers to offer maximum ergonomics and an elegant visual appearance. From there it was forged from alloy, given a replaceable rubberised grip, and finished with a carbon lever blade. The lever is matched to a black flat mount calliper, designed to offer controlled braking at any speed.Please Note: This brake is for handlebars with a diameter of 22-24mm. Brake system comes pre-bled, with lever disconnected. Please see  for fitment information.
