Pads: Heatsink - Whites Time used: About 2 hours Rim used: Onza Ronnie Grind: Yes - light/dead Ceraminc: No Brake used: Magura HS-33, water bled, Echo booster. Rb Lever What is your opinion of a working brake: Holds with out fail, No slipping, with a lil modulation. Doesn't wear fast. A nice noise too. How do they compare to previous pads you have used: Better than Koxx greens, not as good as Zoo! (Zoo was on smooth rim with tar!) Yet Review: Got the pads on the bike, set them up really good, too. Had a quick ten mins messing about on some curbs. They were really good, noise? Hold? Slipping .... hell no! Went out for a ride. Really good pad. They only slipped one, or twice. The only reason that was cause I hit the pallet with about 20% power as I was fecked. One of the bad point about these pads are they are pretty spongy , They lock and I could keep on squeezing them about 1/2 a cm. No noticeable wear, which is good. I'll edit when I can ride again. I'll put a better grind on too.
