Shimano makes two types of rotors (narrow and wide) and two types of pads (narrow and wide), they don't recommend using wide type pads on narrow 2 piece rotors, the pads used in the Spyre/Spyke brakes are exactly the same as Shimano wide type pads, the rotor you're using looks to be a Shimano narrow 2 piece like the RT76 / RT81 / RT86 / RT-EM800.

I've seen a few photos of wide pad use on narrow rotors, the pads were overhanging the inner edge of the rotor and wearing on the arms of the rotor.

What you can see from the outside looking in, mightn't show the full story, after a bit of use I'd remove the pads from the caliper to see if there's any unusual wear on them.

Whoa. I did not know there were 2 rotor widths. Yes, the pads do hang down past the rotor and encounter the rotor arm, the rotors are XT level, unsure of model number. Well frig, I have to get new rotors now. <sigh> Does the pain ever stop?

Thank you for your help.

...on the brighter side, this allows you to buy the Titanium brake rotors that you really wanted all along.

I think (people correct me if I'm wrong) a rear 160mm adapter has the same geometry as a front 180mm adapter (I know Shimano has separate models for 180mm front and 160mm rear), so (I think) you could get a 180mm rotor and turn your current adapter right side up and it would work.

It would probably work, SRAM doesn't have front and rear specific adapters, they have a 20mm IS adapter that's for front 180mm and rear 160mm




Does the following image shows how the pads are contacting the rotor?

If it does, it would be an indication that something isn't right with your setup
