I put these on 2 bikes. I found them hard to adjust and nearly impossible to keep from squealing. Kool Stop salmon rubber is great, but I suggest you use the Kool Stop Supra 2 or Eagle 2 instead of this style. (Supra or Eagle depends on the mounting hardware of your brakes.). I find the Supra and Eagle styles easier to adjust and less squeal prone.
Bottom LineYes, I would recommend this to a friend
I really like the KoolStop Salmon rubber. For me it has given less rim wear, improved wet braking and fine dry braking. I found the Mountain style pads difficult to adjust and prone to squealing. I prefer the KoolStop Supra pads with Salmon rubber. They are easier to adjust and I have experienced much less squeal with them, even installed on the very same bike and wheel.
Bottom LineNo, I would not recommend this to a friend
