I had the original brakes that came with my Triban 120 for about 10k km and they were poor. Especially in the wet, they were absolutely ineffective.
Changed to these dual compound Kool Stop and my feeling is that these pads are 50% more effective than my original ones in dry. Not experienced them in wet as yet.
Koolstop Salmon are a good pair of replacement pads - I changed from the OEM pads (R539) as they required a good amount of effort to apply.
These require slightly less amount of effort to apply, I was expecting more. Stopping is better than OEM, just wished it required less effort to apply. Make no mistake, they are better than OEM.
Where these shine are in wet and semi wet conditions - The stopping is really good.
Would I buy them again - not sure, Maybe!
