Great stopping power and quiet in the dry. Not had chance to use them in wet conditions

Not my first pair of semi metallic pads from Gorilla Brakes. Ideal pads for my style of riding, good compromise between sintered and organic pads plenty of bite without wet weather squealing you can get with sintered pads.Good value and prompt delivery.
