Organic vs Sintered...

[fredintoon]

ive got these fitted all round on mine and couldnt be happier, they dont squeal
and pull the bike up real well even at speed.
no problems with the wearing of the rotors either.
they do have to be bedded in well tho. - - -

Hi Pete,
but what are they? The package says "Sintered metal" at the bottom and "Ceramic Carbon technology" along the top.
So they are manufactured by a sintering process but as Carbon is the basis of all organic life they must also be organic? 50% this + 50% that? 100% hype?
So long as they work, right?

Hey Fred,
no idea, thats what the guy at the bike shop
was selling at the time,
all i know tho, they do work well at all speeds.

That's why you gotta use cobalt steel drill bits to make holes in them and why they are eff nigh impossible to re-surface to a good finish.

Just a bit of a thread hijack here, but I gotta point out that when I drilled a set of rotors for Black Ice, I used one generic no-name brand HSS drill, and was still getting cuttings like this when I finished the last hole on the third rotor:



I did use a good drill sharpener after every 10 or 15 holes, and sharpened to a split point configuration, but there was nothing exotic about the drill.

YMMV

What did you use for cutting fluid? That can make a big difference...
