You guys crack me up. Just about everyone on this forum takes everything superlite says as the gospel. Nothing against superlite and I am not trying to be disrespectful to him in anyway, but come on....
I've had these brakes on my bike for more then a year and logged about 4K miles on them. The bike these are mounted on is a 13.85 pound LOOK KG281 and I have had no maintenance problems or stopping problems with these brakes. I've run them on Ksyrium wheels and American Classic carbon wheels with absolutely zero problems in braking. I am 155 pounds and a fairly aggressive decender down the North Georgia mountains. Granted they aren't as high as superlite's mountiains in Colorado, but they are just as steep and the curves are just as sharp. There is one mountiain here called Hogpen that if you don't use the breaks you'll easily hit 60mph. I trust these breaks to handle any emergency situation I encounter and they have yet to fade out on me. I've used Shimano Ultegra and Dura Ace brakes and now using 2004 Campy Record brakes on another bike and the CAT brakes stop me better then any other brake I've tried. I would like to add that the pads that come with the CAT brakes absolutely suck and should be replaced before using them. I replaced them with Dura Ace carbon pads and have had great luck in dry or wet conditions. I've been lucky in the fact that the guy who makes these brakes is about 30 minutes from me and I actually had him set the brakes up for me. That being said I have to wonder if superlite has them 100% dialed in. The directions are pretty clear that if they aren't set up exactly right then you'll experience some of the issues superlite brings up.
My point is don't take one person's bad experience with something as the gospel as you could be missing out on a great addition to you bike.
hmm, i will change the pads on mine, but i have yet to have a problem with them. superlite may have more exp. and more hill time since he lives in colorado (so i am inclined to believe him in a way). mechanically the dura ace and campy brakes have more leverage than the cat's so they may apply more pressure to the rim, and in high speeds slow you down faster; but i dont know how much better they are, is it a big diff. superlite???
