220mm Rotor

View attachment 49289
Definitely have more feel with it, same awesome stopping power with better modulation, and doesn't it just look the biz... now tossing up whether I need one for the rear end too? Looks like it would fit easily with the same adapter.
Didn't get any of the hitting the rivets issue that was talked about in the reviews when I ordered it, which was a bonus.
Lovely! ?

May I ask how much they were? And if you know, how much weight did they add?

The disc was very reasonable at $106 AUD and the adapter was $14 so about 50c a mm which I think is great value.
Didn't actually weigh it before I put it on, and lets face it, can't be much more and we are on E-bikes. Looked on the website I bought it from and it only had this "146g for a 180mm rotor" in the description. So with a bit of maths I get around 180g for the 220mm rotor. Hope this helps.

Was asking about the weight because some manufacturers say that they put on smaller rotors to save weight. In theory that's correct of course, it's unsprung and rotational weight too so it's the right place to save any weight. But I doubt 40 g would make such a huge difference compared to the increased braking performance.

For reference the Magura 220mm MDR-P weighed in at 240g, 60g increase over the 203mm Shimano RT-66 at 180g

Couple of pics. Magura rotor, XT 4 pot caliper, sram 40mm adaptor bolted down with m6x18mm Ti bolts. Fits great. Just popped a new damper on the fork so can't wait to test it out together. ?

Very good. Do you still have the conical washers on the caliper bolts? These are not required with this style of adaptor - ideally you will want an M6x18mm bolt with just a flat washer.

I run Magura MT7 (2-pot caliper rear) with 220 mm MDR-P rotors for more tan a year. Superb stopping power. But beware: magura 4 pot caliper doesn’t fit under seatstays! Only 2 pot and only 180 mm or 220 mm rotors! Had a fee fantastic days until I sattled on 220 mm rear. I’m 116 kilo and have no complains on power even with Performance pads.
Friend runs MDR-P 220 rotor with Shimano brakes without issues.
