Considering Open Pro Ceramic Rims(7 posts)

Do they stop better than regular rims? Don't you gotta have special pads? Are they worth the extra money? Like the idea of a good custom wheelset over those expensive poser hoops going for a kings randsom.

I have a set that I have had several years. They are not worth the extra money. The regular- black, blue or silver will do just fine.

I initially bought these thinking that they would improve wet weather braking - they don't. Also, in a race, if you can stop quicker than everyone else, so are prone to get run over.

When the ceramic coating is new, it eats up brake pads. After a while the coating smooths down to where brake wear is no worse than a slick aluminum surface. The only benifit that I have seen is that the rim surface lasts longer. Since the braking surface is harder, it doesn't get chewed up with road grit by the brake pads.

I have some of these rims too. I initially bought them for training wheels, and I also thought they sort of matched my Ti bike - go figure. IMO the coating does help a little when wet, and like the above poster mentioned, it REALLY helps when dry. Use Kool Stop salmon pads and you'll stop RIGHT NOW. The only caveat I have is the coating wears unevenly on the braking surface and looks a little funny. These wheels have about 12K miles on them and no cracks or similar from the hard anodizing. Let me know if you want to see pics of the braking surface and I'll post some.

I've shoped around and the Ceramic open pros are about $40 a rim more than the regular open pro rims. Varmit dosen't seem to think his were worth the extra money. I noticed there also about 25-30 grams of outward rotating mass heavier than regular open pros.(not really concerned about that.) I don't have a Ti frame but also like the look of the ceramic. I noticed on the Kool Stop website, they have a break pad for ceramic rims. They call em Z-chromiom. Look like the color of the rims. Also noticed that they (the ceramic open pro's) are only avalible in 32 or 36 hole drillings (also fine with me). With the upcharge of the ceramic rims and labor for custom build am getting up there in the Exotic Wheel price range (Kyrims, Euris, CR420's). I do like the idea of Better Braking and long wearing rims. Not much of a treand chaser so I'd like the rims to last a long time.

In addition to what the others have said, if you get a chip in the coating it will feel like an uneven rim joint.

Get the regular machined sidewall version with the raw Al. The braking power is excellent (much better than the CD version).

with ceramic pads IMHO they stop better than regular O/P's
have a set of both and they seem to last a bit longer. I use mine for wet training and have used them in cyclocross.

I always ride the regular silvers. I can't imagine anything needing to stop better than these with any modern quality brakeset. The ceramics I've seen look like crap after some miles with a "wavy" wear pattern through the coating from the brake pads. yuck.
