Pads: Koxx blues in cnc backings. Time used: 2weeks Rim used: revell Grind: Yes and no, I'll give more info Ceraminc: no Brake used: Magura/V What is your opinion of a working brake:Amazing hold, amazing bite, amading wet weather pads. How do they compare to previous pads you have used: Compared to the onza citrus, out of this world. Review:Well, I first started on smooth rim, where the bite was insane, hold was pretty good. This was on a smoothened down rim. Then tried hem on a light to medium grind and they really showed what they are made of (no they did wear stupidly quick:P). In my opinion, they work just aqswell in the pissing rain as they do in dry weather; if not, better. With the aparted to 2 bolt zoo! booster I have the hold is imense and I wouldn't look for any other pad.
