Strengths: Light (5 grams per pad), good braking power if it doesn't rain hard
Weaknesses: Very poor power when it rains
I have used these pads and was pretty happy with them till one day I was caught by some heavy rain. I was on the top of a hill and wanted to go home. The brake was just not effective enough to stop the bike with wet rotors. Under dry or mildly wet conditions, however, these pads were just fine.
