damn

i saw some dude today on Trek with some fancy disc rotors, it looked like flame or somethig
do they perform like regular rotors? i have bent rotor at rear whell, so i was planning to get new rotor for a while now..
can you point me to the website or something? thanks

btw my rotors 160mm

It also depends on thickness of the rotor. Each company uses a different thickness. As for where...I forget, there are a number of custom rotor makers

I have a set of these and I like them just fine. I've noticed a bit of an effect on braking for the better. I could have with a $15 Diacompe replacement rotor and been fine, but what the heck I got them wholesale so what do I care? They look killer in my opinion.

That is a sweet looking rotor. Mine is round...

Where does it actually grip the rotor? There is no patr on that rotor, that I can see, that is the same distance from the centre fo the whole 360 degrees.

Erm... isn't that on backwards? I thought the "fingers" were supposed to point forward... at least that's how the moto guys run em'

I doubt the fingers make any difference, after all it's a (somewhat) round rotor moving around between two friction plates. Either way, it's a cool looking rotor.

I jsut wish that my rotors didn't have the mirror polish that builds up on them after a while of use.

it would make a difference on cooling. Just like standard discs have a certain way to spin to reduce warping and increase its ability to cool...

but yeah they are cool looking

I've tried them both ways and this way works better for me. There's another reason I run them this direction: flex. The way disc rotors flex in my mind its better to have the tooth ramp into and across the pad from this direction because the leading edge of the tooth moves across the pad in sort of a snowplow pattern maximizing the gradual sweep effect as opposed to having the flat edge chip the brake pad as it is bent into line. (Destroyed a set of pads this way) This way the forward most point of the pad moves outward pulling the point more into alignment terminating at the point of the tooth rather than the point starting things off. As for the Moto guys they don't care, they look more aggro the other way so what if they chew pads.
Not sure I follow ya there Cheif they grip the same way as a normal disc only these allow for a sweeping motion that allows better heat distribution / disapation. (not like that matters on a mechanical setup)

Hopper

Sorry I wasn't clear, i think you answered my question. What I meant was, ther is no part on surface ob tha rotor that is where the pad would grip, that is shaped like a normal circle ie not wavy.

What I think you said is that the pads grip the wavy part, and this helps it keep cool. If correct tell me, if not or you don't understand don't worry, I can't think of another way to explain it.

wow hopper, ease up. This is getting confusing. Basically there is always SOME part of the rotor the caliper can grab, otherwise it wouldnt work. Simple.

Reggie

i think hopper is just trying to say the contact patch (pads to rotor) on that rotor ain't too big, creating less friction, less braking power than most other conventional disc rotors. Don't take me wrong, they are nice brakes though

Raiyn

That's the gist of it. There's actually about the same amount of contact area on a wavy rotor as there is on a regular rotor. Instead of holes in the rotor surface as on "normal" rotors these use the wave effect to cool them. If they didn't have something to dissipate heat there would be warpage as in the case of solid discs due to the fact that they aren't able to dissipate heat as well.

Hopper

Thanks, I finally get it

Raiyn

I try.
