Even the 1.8mm thickness ones mate? (Standard floating rotors)

Hmmm, everywhere says 1.8mm is minimum thickness for Magura (below 1.8 is a worn disc for their callipers).

Might just opt for these rotors if I do go the Magura route.

For those of us riding these trails we all switch over to 220mm MDR-p magura rotors (6 bikes). Some of us, including myself, switched to MDR-p 203mm on the rear. 220mm on the rear was not necessary mostly because of my weight (165lbs). We all kept 220mm on the front. (Btw, Santa Cruz, cube, and 4 Rails). I think a heavier rider might want 220mm rotors on the front and rear.

Heat dissipation and longevity is key. Magura claims that the MDR-p is also lighter. On one of the MDR-p rotor there was a ringing or tambourine sound when riding over rough terrain. Clearly the rivots were too loose on the floating rotor. Returned that one. Problem solved. No one has had a warping issue with the thicker rotor and they seem to last longer.

I suppose I’m a magura fan-boy…but they are very good brakes.

I don’t want the MDR-P rotors. Too noisy. (Had them before and they float too much and bobbins make a horrible noise).

Hope has an e-bike specific rotor, it’s a one piece HD rotor that’s 2.3mm thick. It’s what I’m currently using on my Levo Pro, they’ve been great.

I’ve just fitted some mt7 brakes and used the TRP 2.3mm thick rotors for half the price of similar rotors. Got a pair of 203mm rotors for £50 posted when they were in stock a couple of weeks ago.

I think I'm going to stick with the XT's for now. reading loads of reviews and I cant find anything to convince me I should change them. Maybe after I have done a few longer descents I will have a better idea of how they compare to the Hope Tech 3 E4's I have been using on all previous bikes (which in my opinion lacked ultimate power but had loads of modulation). My only gripe with the XT's is the on/off nature on dry loose or sloppy surfaces.

The XTs are good brakes, I have them on one of my Amish bikes. I would do a rotor upgrade and call it good.

I’m running these too. They work great, the thicker rotor improves lever feel with a slightly earlier bite on my mt5s.
