FR150M 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. FR150M Metal Pads can be used as a direct replacement for Shimano A01S, M06, M07, M07Ti 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.
