For street or off road use, the hybrid carbon impregnated X formula pads deliver medium lifetime with powerful cool rotor temperature braking due to the carbon granules within the material. Extremely popular on ATV and MX sport bikes in non-contaminated riding conditions or streetbike enduro models. For longer life or extreme mud riding, see the EBC Brakes MXS series pads or for ATV the R series heavy duty sintered pads.
