Pads: Rock Blue Time used: Since December 27th Rim used: Alex DX32 Grind: Medium sharp Brake used: Magura HS-33 2004, Standard maggy hosing, water bleed, no booster Previous used pads: Plaz crms, heatsink Xmas pads, Zoo pads old style, koxx blue, brown, red, yellow and green. Review: I ground my rim, Medium sharp grind, Set these pads up, spot on. Spun my wheel and pressed the brake, My dad come outside and asked me if someone had been shot...I goes no, thats my brake. You guessed it. Mega grabby and bitey, STUPIDLY loud. So i went out for a ride and i've never ridden with a brake like it, I was so confident, i purposely landed right on the edge of everything to test these pads to the max, did they slip ? Nope not at all. I wouldn't say they matched my Old style Zoo pads on a smooth but no brake set up will ever do that. Overall 2nd best brake pad in the world. 100% recommend them. I've just got a sponsorship from Necopads, so once they come through, Ill ride em and give you a review Danny.
