Fitted with stainless steel radiator plates for bikes without built in piston insulators to reduce heat transfer into hydraulics and new double compact vented technology for wider pads; reducing backplate bending. HH Suffix = High Performance Sintered Pad The Extreme Pro is a range targeting the Race market both street and off road but so many bikers have expressed an interest in the product we have extended it to a number of popular sportbikes and cruisers. For this reason we can expect sales to the high end Street market also on this new line. The pads are a VERY expensive blend of sintered bronze including new age materials such as Tungsten and Moly metal to bring you the grippiest; most fade resistant pad we have ever tested. We tested 7 other materials in developing Extreme Pro and the graphs opposite show the BEST of those competitors whom we have comfortably beaten with our new blend. Extreme Pro completely replaces the GFA range which will be now phased out.
