The G1375 compound is the result of many long days at the race track and on the brake dyno. Based on Advanced Ceramics, this compound is meant for the track. It offers very fast heat recovery for more consistent braking which in turn, gives the rider more "feel." This is the pad of choice for most racers at the top of club levels and AMA contenders. These pads are very easy on rotors since they do not have the same levels of metallics in them like many O.E.M. and after market brands. The G1375 compound also features a ceramic coated back plate which helps to dissipate heat away from the brake pad and reduces the amount of heat transferred into the caliper pistons. This gives you a cooler running system that will be able to withstand more heating cycles and deliver consistent braking. Sintered metal. Ceramic coated back plate Powerful and progressive braking. No fade effect. Low / null noise levels.
