HD-T910 is a fully hydraulic disc brake specifically designed for time trial and triathlon bikes. It integrates the previously external master cylinder into the handlebar grip, thus fulfilling a further function as a driver contact point. The co-moulded rubber grip slides easily over the end of a standard 24.2 mm TT base bar, therefore no handlebar tape is needed. The modular grip system is designed to neatly connect to modern electronic gear shifting systems and does not require adjustment after assembly.
