The all new Hylex HD-C8110 hydraulic disc brake features a slimmed down hood profile and new ergonomic lever blade that matches the form of the TRP HyWire Pinion and TRP Vistar Classified electronic shifter/brake levers. Pair a front and rear Hylex together for your single speed drop bar bike, or run a left only and pair it with a HyWire or Vistar shifter lever.
