FR120M Metal Pads use a metallic friction compound made from a sintered blend of high friction metal powders. The performance advantage of these pads is their consistency in all conditions including serious mud and long steep descents. If you’re a big fan of that sort of riding (we are), or are on the heavier side, metal pads are a must. Metal pads also last much longer than other compounds. FR120M Metal Pads can be used as a direct replacement for Shimano K03S, K04S, K04Ti, L03A, L04C pads and other pads with the same shape.
Metal pads will keep you stopping all day... on any slope... for months...
Wetter might not be better, but riding always beats not riding.
So far so good. Cheap pads but do the trip. Running in shimano brakes. required proper bedding in but so do all.
