I recently upgraded to Di2 Ultegra. The brakes squealed at high speed braking so I gave these a try. Perfect Upgrade! Since then I got a set for 2 other of my bikes and for my girlfriend as well. These are a must have component.
SwissStop pads were OEM on my Focus and the original pads lasted over 2,500 miles. They stop well in wet & dry conditions. A little pricey compared with Kool Stops but when it came time to replace my original pads there was no question that they'd be SwissStops. Happy with the stopping power--no problems.
These were a snap to install and after 1000 miles on them, on new wheels installed at the same time, I'm quite happy with the performance. I may change the rating once I've ridden them in the wet...
Seems I upgrade to Swissstops as soon as the original pads that come on my bikes wear out. These things seem to stop well, last long and have great break feel on my bikes with either campy chorus or shimano DA brakes. Might not be quite as long lasting as Campy pads, but good enough.
I've switched all my bikes to these pads. Other pads I've had seem to pick up small metal particals and other stuff that gets embedded in the rubber and then wears the rims. Not these. So they are very friendly to your rims and won't wear them out as fast. Seem to have very good stopping power too. I cycle about 6k miles a year. But almost all on dry days. On the few wet days, these still work well.
Those who use alloy rims and do high speed technical descending can expect no modulation or pulsing whatever the weather conditions are. these are the best pads available.
Got a four pak. Enough for both front and rear brakes. The pad materials and their construction
look just perfect for my planned usage. Have not as yet installed, but will soon before the 100 miler coming up
