I'm not a competitive cyclist. I am your typical fred when it comes to go-fast parts. I got some carbon wheels with brake tracks, and these pads to match them. The stopping power is great when dry, but (as I'd been warned) slow to come on in the wet. The think that shocked me the most is how quickly they wear out. I'm down over 1mm in less than 200mi of riding. I'm 200lbs, for what it's worth.
This replacement pad is of the same value and performance which comes standard on my Lightweights.
With a clean carbon brake surface, these pads will NEVER Squeak!
This is a great value and well worth the purchase.
