I used gorilla pads in my road bike and found them easy to bed in and they have given me good braking all winter. It was an obvious choice to order gorilla pads for my Mtb. After the post office lost them gorillas customer service was top notch, the second set arrived with the first the next day. Gorilla supply good pads with perfect service and I can’t see me using anyone else now.
