Re: What do we know about these ebay wave rotors

I have also been watching these rotors with a weary eye. If you check out their feedback, the people who have gotten them seem happy. The only thing I can see that may be bad is they are only 3.5mm thick. Now thats nice to decrease the rotating mass, but I believe it makes them more prone to warping under heavy braking situations. I'm not a mechanic or a metallurgist, but thats was my first thought.

Re: What do we know about these ebay wave rotors

It says they're 5mm thick though on that page.
Thinner discs can be more prone to warpage and boiling your fluid as they can't dispose of the heat as quickly.

Re: What do we know about these ebay wave rotors

5.0 - 5.5 mm seems to be the thickness of most oem rotors. I would not feel comfortable with 3.5mm rotors. As cheap as they are, it would blow if they warped easily and had to be treated as a consumable and replaced regularly like the brake pads.

Re: What do we know about these ebay wave rotors

yea the price is very attractive but I wonder if it's just the fact that manufacturing is cheaper in asia, the material/quality is lower, or a mix of the two.

It does say the rotors are 5 mm thick... the thinnest that comes OEM on any bike is 4.5mm on the front rotors.

also their designs are straight rip-offs of genuine companies like Braking (for the rotors) and Sato (for the rearsets). China doesn't really care about patents or copyrights and I'm leery of supporting such plaigarists

Re: What do we know about these ebay wave rotors

I've swapped email with Toby Huang last year as they do titanium machinework as well.
Don't think I actually had to do any dealings with him at the time but he seemed helpful.
He was considering titanium disc carriers but I think I managed to convince him it was a pointless exercise.

also reminds me of an article that china buys up most of the world's titanium supply, so maybe Ti is a cheaper material in china?

Re: What do we know about these ebay wave rotors

It is but it's illegal for them to export raw ti.
They can fabricate ti parts very cheaply though and export them.

Re: What do we know about these ebay wave rotors

Perhaps you're assuming that the more expensive something is the better the quality? By that reckoning you should be wondering why you're trusting your life to the ones Honda mass-produced for about twenty bucks each :-)
There's nothing mystical about brake discs.

" There's nothing mystical about brake discs."

I always thought they used some kind of expensive metal alloy, why else would oem brake disc cost so much?

Re: What do we know about these ebay wave rotors

The best ones are cast Iron. Not much mystery there.
I saw a manufacturer tag on the rotors but couldn't make them out.
One thing though, If I were to buy wave rotors, I would only buy full floating rotors, not semi. Why spend the money to have neerly the same type of rotor as stock?
