Most manufacturers build bikes using sintered metal pads and these are direct replacements for that technology with several differences. First the refined compounds researched and used exclusively EBC are second to none in terms of quality of materials and workmanship. Secondly almost all EBC Double-H sintered pads use EBC design perforated stainless steel heat and noise shields on the reverse side keeping brakes cooler by reducing heat transfer into the bikes hydraulics and dampening noise.
