What robust rotors?

Topic starter
 

I'm fed up with my Shimano Ice Tech rotors warping or rather being warped.  Not having any success straightening them out properly so does anyone have any recommendations for more robust rotors?

Ok they're quite old and were 2nd hand when I got them so that may be a contributing factor.

Happy to look at the 2.3mm options if that improves things. What's good and relatively cost effective? THE TRPs look quite good and have a wear indicator which I think is a really good idea but I am quite fond of Hope stuff.

The brakes are 2 pot XTR if it makes any difference.

I’m using SRAM HS2s and have found them to be bullet proof so far.

I’ve just put on some 2.3mm TRPs. Wasn’t expecting a change to performance but quickly adjusted said expectations on their first outing at the Golfie. Somehow seemed to brake better (stronger) and my brakes have never felt so consistent over a run. Would recommend.

Magura are all 2mm. Galfer come in 2mm ebike version, the shark rotors look great. SRAM HS2 are 2mm. TRP/Tektro do a 2.3.

I'm using Magura in my Shimano SLX calipers. Seem good and have stayed straight so far. They give a very slightly firmer lever feel too due to the increased thickness.

I run Hope floating rotors on a couple of bikes. Never had any issues, and they are very robust. Look cool too.

I retired a 203mm one last year that had seen 10+ years of use and abuse. It was still straight, but quite worn down thickness wise!

Also they make a nice pinking sound when cooling after a long descent 😁

I run Magura Storm 2mm and they seem to stay straight until they wear out.

SRAM seem good. Actually the really brazen SRAM copies on the internet also seem pretty good (if you want to tell them apart, it's easy, if it costs like £6 it's fake) Formula's old old old design is also very tough, but not anything they've made sense.

Probably the same ones, I got some from amazon. I don't approve of copies, mind, but I was just looking for a cheap-ass set of discs and they came up, SRAM didn't lose any money by it 😉

I’d just been looking at the Centrelines on Ali actually… assuming there’s not a great deal that can go wrong 🤔

I had some Magura MDR-P in 220mm and 2.0mm thickness, likes others have said improves lever feel. One of them developed a rattle as they're 2 piece so went to SRAM HS2's and have had no issues. Dont squeak in the wet like my OG Centrelines did either!

Magura 2mm MDR-P with sintered pads in SRAM G2 calipers. Working very well. No clearance issues, very good floating design and teh carrier is pretty damn stiff so the disc is running very true and the wheel spins very freely.

Interesting bonus, the SRAM lever feel is much improved just by pushing the pistons in then as its a 2mm disc, not moving so far before they come into working range. The old centreline disc created an increasingly spongy feel as the pads wore and teh pistons extended. Non of that so far. Very pleased and they were €39 for the 220mm version and €44 for the 180mm rear.

Those who run the MDR-P does the tinging bother you when they get hot and expand?

Are the TRP 2.3 too thick for Shimano Saint callipers??

The standard shimano floating rotors are pretty good, ime.

Same look as the ice tech, but solid steel and no warping issues.

Recently replaced rotors on the GF's bike after 5 years of brake dragging. Went from 2mm to 1mm.

The Magura MDR-P look great, feel great and are near silent but they wear, on the rivets I think, and are then noisy, sound like you have loose spokes, wouldn't recommend.

Decided to stay away from floaters so have some of the Galfer Shark on order, wasn't pleased to see that post from Singlespeedstu! But then my bike was nicked last week so I haven't got anything to out them on at the moment. Sad times.

£52 from Bikeinn. Which is still crazy to be honest. And if I hear of one more catastrophic failure they'll be getting returned! I'm hoping the one above was an unfortunate crash onto a rock

I've started replacing 1.8mm rotors with 2mm, 2.3mm may be a little excessive and getting heavy so I think 2mm is a good middle ground. Uberbike's 220mm have been performing well so far, decent price and weight too.

@hainman

In theory, yes, in reality the clearance is so small that you'll drive yourself mad trying to eliminate that last bit of rubbing. It works, just be prepared for swearing.

@singlespeedstu - on the contrary, if you look closely some sections of that rotor appear to have completely worn away!

@hainman The tinkling sound is similar to the Hope Floating noise when cooling, so no.

MDR-P when hot and starting to bike again sometimes have that "flock of turkeys" sound like the pad spring is rubbing but it goes silent again very quickly. Can't fault them.

I suppose you could say it's around 75% worn yes.
