I installed Kettle's SiCCC rotors a few days ago on a cross bike (that I actually use as a winter road bike), and I'm happy to report that they work as well as the steel rotors I had before. Might be a good option for road disc.

I put a detailed review and pictures on my blog, but briefly make sure you follow the bed-in procedure properly! Without the bed-in procedure they only offer about 50% of the braking strength of a steel rotor, after the bed-in I got about 90%, and a few dozen miles after that they are indistinguishable from steel rotors.

I actually didn't buy the rotors because of the weight, I bought them in the hope that they'd reduce the screeching and chattering I'd get with steel rotors. They do: no squeaking, just a quiet sanding noise when I first apply the brakes. I wonder what's happening to my pads?

Thanks for the info on the rotors. Your blog has some beautiful pictures of the Catskills scenery!

160/160. I put them on a Lynskey that I use as a winter bike.

I just got back from a longer (50 mile) ride with them, and they seem to be getting even better.

The "sanding" noise they make when braking is a little odd. I am concerned that I am going to go through brake pads quickly. I'll take the pads out and look at them after 200-300 miles.

Oh, one thing I will say though is it is really nice not to have screaming brakes. No matter what I did the old BB7 stock rotors screeched like hell when they got wet. These are completely silent.

Pad wear will be interesting, but there is mo reason for it to be much different.

Do you notice any difference between cold/hot braking and dry/wet at all ?

It has been wet and raining since the day I installed them, so I haven't been able to compare with dry conditions.

As far as hot/cold, I'm not sure how I'd test that efficiently. They work fine from the start of each ride though, and don't appear to get any better.

I ordered a 203 mm SiCCC rotor for my tandem, and it will probably ship this week. I look forward to putting it to the test on stopping power and heat management.

On MTBR forum, users think these don't have the stopping power of steel rotors. If I find that out as well, I'll just use them for special events like hill climbs.

No, nothing of note. They are still working fine. No problems in the rain, no problems with big descents down mountainsides. I've pretty much forgotten they are there.
