Pads: heatsink cousts in pimp metal backings Time used:2 months or so Rim used: rear revell and then a rear 24bicycles 42mm rim Grind: hell yeah,sharp med Ceraminc: nope Brake used: 05 maggie,zoo! lever,water bleed no booster What is your opinion of a good working brake: on/off ,loud ,solid lever feel and excellant hold Previous pads you have used: koxx browns ,cousts ,zoo! ,onza citrus ,rock pads greens ,rockpads blues ,maggie blacks Review: i started using these pads on my reveel rim which had a dull med grind on it,after setting them up nicely i went for a ride,and instantly they appeared as if they were bedded in already ,great hold,bite and sound like a horny goose these pads also seemed to get better and better as i used them for longer and longer too. then i bought and 24bicycles rims and whacked a harsh grind on it and set the pads up,instantley i had the same performance as my old rim even though i slightly rushed setting up the brakes so all in all ,im very impressed with these pads bought another set off these along with hs reds the other day,i'll let you know bout the reds in due course . steve
