Sold as a pairs, these Kool Stop pads are an excellent alternative to a stock Shimano pad holder and are the preferred choice for many riders. Kool Stop refers to these pads as "rim friendly" because the compounds used tend to cause less wear and grit on the rims. Vented ribs allow for cooling of the pad and rim. Choose colored pads for different conditions.
I have been using the Salmon/Red pads for years in Phoenix. They stop great, no issue with this. The compound is softer and it does not pick up grit. Check out the stock black pads and you will find embedded grit, and then bits of aluminum. This pad wears quicker, but it protects the rim surface. Swear by em.
This review is for the black Kool Stop pads. I swapped my DA7900 pads for some Kool Stop. I was expecting to be able to lock up my wheels but braking actually became more difficult. When I needed to stop quickly, I had to brake so hard that I was actually concerned about breaking my cables and/or my DA7800 shifters. Seeing that everyone else gave these pads such great reviews, I gave the braking surface on my wheel set a good cleaning to see if that would help. It did not. I tried my other wheel set to see whether or not the braking surface on it would behave differently. It did not. Both wheel sets are aluminum, Bontrager & DT Swiss. Needless to say, I felt that these pads are a waste of $. After switching back to the DA7900 pads, braking is much better.
These brake pads are a noticeable improvement over the Shimano Dura-ace pads, but its not night and day! I could lock up the wheels with the Shimano pads, so the improvement is in the controllability (is that a word?) of the stopping force (aka modulation). I dont think the ultimate stopping distance is much different, but the Kool Stops give you a much better idea of what the wheels are doing, which makes me more confident taking the wheels right up to the point of locking up.
Ive tried both the salmon and the black. For the conditions around here (Bay Area, CA) I prefer the black most of the time. They are less affected by heat, and I do lots of climbing and descending. For rainy months, I will swap in the salmons.
These pads made my low-end (Cane Creek SCR 3) brakes come alive with TREMENDOUS STOPPING POWER. I was so impressed that I replaced my Shimano pads with Kool Stop for my 105 calipers. If you dont watch it and brake hard, these pads will send you flying through the air. Yes, these pads are that good. Best pads on the market.
I have ceramic rims and use the green pads. They are fantastic. Compared to Dura Ace black pads they last at least twice as long and provide at least twice the stopping power. Granted, the Dura Ace black pads that I was using may or may not have been made specifically for Ceramic rims. Regardless, I will continue to use the green colored Kool Stop!
One of the best purchases Ive ever made. Allows you to stop in the rain as if your rims were dry. Made my brakes feel much more powerful, which is important because I spend a lot of time riding in downtown Atlanta.
