If you’re not sure what to choose, specify Green compound. Good lifetime and stopping power. All EBC bicycle pads are made using magnetic stainless steel backing plates. For systems using a magnet for pad retraction these are ideal but for all bike systems the benefit of a stainless steel backing plate is self evident. For all systems which use a spring clip for pad retraction, EBC includes NEW improved strength retraction springs. Many bicycle brake rotors are NON hardened and have the words “Resin pad only” on them. It is critical that when you see this marking that you use a pad similar to EBC Green which is very low in its rotor abrasion features. Disc pads for bicycles have been around since 2002 and selecting the right compound for your needs is not only wise but essential for numerous reasons. EBC offer three grades of pad compound. Another great way to improve your bicycle brakes is to upgrade with an oversize brake rotor kit.
