All my bikes and pointless upgrades: Fairlight, Stooge mk5,

tldr: nah they’re fine

Well so far there’s zero rub…
But I guess there is slightly more potential for it to happen since it’s taking up more space.

I think it is largely down to the individual though, if you don’t take the time to centre the caliper perfectly and ensure the rotor is perfectly true, then yeah, rubbing is more likely to occur.

I admit I’m definitely towards the obsessive nut job end of the spectrum when it comes to this sort of stuff. I did spend about an hour or so just making tiny adjustments to the calipers to get them perfect aligned.

Part of the idea, along with better cooling/heat management, is that the thicker material is less likely to bend compared to standard rotors, so they should stay truer for longer.

But it’s worth saying they are on my uplift bike where the brakes get cooked on long downhills. They are also clearly heavier in the hand compared to the sram rotors that they replaced.
For normal trail riding, I don’t think they’d really be necessary.
