Road Disc Brakes- Rotor Choice

[spdntrxi]

I'm still waiting for Absoluteblack "raven sl"... spring 2021 now, I'm told

[RDY]

Are they still going to produce the Titanium ones? Which they say are ISO ... But everybody uses CL on the road??

Galfer 160 centerlock

Not really weightweenie
Are the Galfer 6bolts lighter as the centerlock version?

That‘s the MTB version. The road version (Galfer wave fixed road centerlock) weighs 98g (160mm) and 76g (140mm).
Definitely the best discs I’ve used. Can recommend.

Im between the Galfer Centerlock and Xtr Discs for my new Roadbike
Are there real world comparisons between these rotors?
Galfer is lighter,but as good as Xtr?

The Galfer are not worse, nor will I say that they are better

I have used XTR and XT with 105 calipers and Galfer Road Wave (6 hole) with SLX/RS785 calipers

The brake pads are also important. I would recommend the Galfer road brake pads for Galfer discs. No squeal and good power (even on long descents).
Didn‘t have luck with Shimano brake pads and discs.

I have no complaints about Galfer rotors with Shimano pads

I've bought a pair of galfer centerlock rotors, they are indeed very light.
Actual weight 160mm = 98g, 140mm = 78g, included lock ring = 12g each.
Fitted the 160mm on my bike for a quick test and performance seems on par with my existing sram centerline x rotor.

[RDY]

New to centrelock (have previously used 6 bolt).

Can anybody tell me what type of lockrings I need? Do I need to use the chunky ones with external teeth cutouts for locking, or can I also use cassette lockrings with 12 internal diameter teeth?

There seems to be conflicting information. It's for 12mm thru axles on BX312 hubs.

There seems to be some suggestion I can use the smaller cassette lockrings if below 15mm axle.

External will always work if you want to be on the safe side.
Internal works with most 12mm hubs.

In my experience, the Galfer rotors paired with shimano pads have better performance in terms of noise then the XTR rotors with Shimono pads. I have not tried the Galfer pads yet Since I am satisfied with the Shimano one

Trying out something "new" for 6-hole
CarbonTi X-Rotor SteelCarbon 2 brake discs
in 160 mm (78g):
- first impression (with SHIMANO brake pads L03A resin) is good
- came very nicely finished and without "imbalances".
brake performance under dry conditions on the "first kilometers" good
(so far not as aggressive as the Dura Ace brake disks, but well dosed and apparently sufficient for my system weight of u80kg/ unobtrusive in terms of heat and noise - so far (no high mountains so far)
Compared to the FSA, I would not see any noticeable difference in terms of "aggressiveness".
All this only so far, because I tried to brake the new discs and pads in the best possible way - but maybe this can be done even better.
Currently I can only judge distortion and fading on the basis of a few small downhill runs - the X-Rotor were absolutely inconspicuous - braking absolutely evenly until the end of the tour, no "stuttering", no squeaking, no warping...
(Whereas the FSA had to be "bent" once and was noticed with a slight "rubbing" incl. noise - nothing serious, but unknown to me from the Dura Ace before). (Brakes always meticulously bled).

Any aero savings to a 140mm front rotor?

Any aero savings to a 140mm front rotor?

Miniscule.

More like immeasurable.

Hello, did somebody try a XT/XTR rotor on a Campagnolo groupset ? Campy pads seems larger and may interfere with the alloy part of the Shimano disc ?
