Kool Stop Road Brake Pads
Kool Stop replacement pads for Dura Ace, Ultegra, and 105 road brakes. For the ultimate stopping power Kool Stop is the way to go. When you're flying down a hill at 40+ mph you shouldn't have to worry about your brakes. With Kool Stop Road Brake Pads you can be confident you will always come to a Kool Stop.
They work great and have lasted longer than expected.
These Kool Stop pads seem quite a bit softer than the Shimano inserts that I normally use. I don't know how well they are going to last but I am happy with the stopping power and even modulation they offer. I like the price (1/2 the price) too.
