Just was a matter of time before they hit the market. This auction is for TWO rotors...

Any opinions?? Who wants to be the guinea pig?? I'm tempted to give these a try...

No idea about those. *shrugs*

I do like the Q&A at the bottom though:

Q: Hello, This item is two disks rotors or one disk rotor ? Thank's
A: Dear friend, This item is two disks rotors, show as the picture. Kindly buy them with confidence. Best regards. Amy

Pat Goss on Motorweek just did a segment on cheap rotors. He said the things to watch out for were the use of cheaper (lower-carbon?) steel which was softer and would wear faster. Also, at least on vented, car rotors, was fewer fins/supports in the center which might cause them to not vent and cool as well. And, of course, the accuracy to which they were manufactured, machined and trued.

 That's pretty funny - Last year I bought ebay Chinese replacement levers & pegs for one of my other bikes, also from "Amy."  I guess she gets around.
  For what it's worth, the quality was as good as OEM & you couldn't beat the price.

If you wouldnt trust the quality/finish of limited function or full aesthetic bits ( levers, carbon,reservoir covers, etc) why would you risk it on the one thing that your life absolutely depends on?

some things are worth paying a shit ton for.

Finish and functionality are two different things.   I think a lot of the issues with the fading anodizing has more to do with experience  -- a lot of my old factory stuff with anodized parts has faded. 

I've had these rotors on my bike now for a while and have had zero issues.  They barely look worn and I stoppie without trying.  Others have a lot more mileage than me.

Street use, maybe. I wouldnt want to have em on a track bike.

Ive just bought and installed those exact rotors, there seems to be no problems, they fit perfectly, they feel nice when on the anchors and weigh less than the OEM Brembo's.
I had only 24,000 km on the brembo's and they were warped, so for the price if they last that long they will be worth it.
I had them shipped to Sydney Australia in three days [thumbsup]
OEM 3.4kg (pair)
Aftermarket 2.8kg (pair)

for me... i've stopped trying to argue the process vs location debate.  i think every generation will have a country that is making cheaper products that people will say is worse because it's cheaper.  a couple of generations ago it was japan, then korea, now china... once china gets it's quality to a certain level, i'm sure it will be india or indonesia or w/e.  and it's not just from asian countries either... like ducatiz said, 80's ducati quality is still famous for how bad it was, and anything involving the english and electrical auto parts was even worse.  and current english cars dont count because they are all made by germans now.

it's basic and cheaper now... in about 10 yrs you wont care because it will be more expensive and everyone will have somewhere else to pregnant dog about.

the problems ive seen with cheaply made goods is all in machining tolerances, material qualities and finishing practices. of course there are good quality items coming out of china but I doubt the 100$ rotors are one of them.

even if a majority of the rotors have 0 issues, im not willing to be that 1-100 guy that has the bad ones. when you break down the amount of time you will be running them combined with the peace of mind that you get knowing that they came from a factory with quality control and after sales support, paying the extra money is worth it.

I can't comment on any other seller than the one I used, but he was happy to provide their factory's ISO9000 series certification.  The beauty of brake rotors is that they either work or they don't.  In the 23+ years of my riding experience, I've never heard of a rotor failure except where someone modified one in their shop.  I've seen race rotors shatter, but never street ones and never iron or stainless.

Of course, your mileage may have varied and you've seen many rotors fail, but at the end of the day, it simply doesn't happen.

ive seen 2 no name rotors fail, one street use that cracked a portion of the carrier and one that after  mild/moderate track time warped pretty severely.  unfortunately I dont have a clue as to how many miles were on the bikes or the rotors (the track guy had 4 or 5 days on his) but they were in fairly good shape otherwise. 

of course, the counterpoint to this is that even the best companies will occasionally get flaws in a run or two that make their way to the public. All I can say is that I haven't seen any name brand rotors fail personally. Worst case scenario, if your disks did catastrophically fail and verifiably cause a wreck, are you going to have more luck talking with "Amy" about compensation or to brembo?


anyway, in the  long run spending 200 vs 500 isnt that big of a deal when you brake(hah!) it down to a $ per mile type figure.
