FOR BAR DIAMETERS BETWEEN 23-24mm With the evolution of disc brakes on time trial bikes, TRP saw the need for a high-performance hydraulic TT disc brake resulting in the all-new HD-T910. We took a unique approach to the time trial brake by combining speed and style which resulted in the TT Hydro. Initially, the lever was handcrafted from clay before being finished off in aluminum. This allowed our designers to offer maximum ergonomics and an elegant visual appearance. From there it was forged from alloy, given a replaceable rubberized grip, and finished off with a carbon lever blade. The lever is matched to a black flat mount caliper designed to offer controlled braking at any speed. The levers come in two widths for differing bar diameters: For bars measuring a diameter between 22-24 mm: HD-T910 For bars measuring a diameter between 24-25 mm: HD-T912 FF-5 adapter required for mounting caliper to fork
