I have SM-RT53 Disc Rotors on my Cannondale Quick CX Ultra. It calls for resin pads only. But I can't figure out what material the rotor itself is made out of. Anyone have any ideas?

P.S. Here's a PDF with the part numbers... http://techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/BR/EV-BR-M486-F-2883A_v1_m56577569830667244.pdf

Very Nice Bike ! I think most rotors are made of different grades of steel, but unless some one else
knows for sure, you might have to e-mail Cannondale.. Richard

Almost certainly (stamped) stainless steel; there are some high-tech (and uber expensive) variations out there, but real-world bicycle disc rotors are typically that material.

Well, the reason I ask, is because the color is lighter, almost like an aluminum. And stamped on the rotor are the words, "use resin pads only".

I was only taking an educated guess, I can see you sitting there typing with one hand and laughing to
yourself ! A magnet will stick to ( some cheap grades of stainless steel ), but my kids said DAD, what's so funny ?
Even if you did not know, just keep letting me think you did. Richard : )

OK, I'll let you go on thinking I know what I'm talking about. :) I can type with both hands now, tie my shoes etc. but I'm not supposed to lift anything more than 1 pound yet. Doc told me to trim the ends of the fishing line he stitched me with, but I decided to leave it for now.

Wow, you really busted that arm up ! Wished I lived closer to you, I would try and make some deliveries for you, I'm sure you could use the help,
and I would cherish the experience also. But I can only wish you the best ! Richard
