Time to do some maintenance to my main bike (a Niner ROS9 I built about 3 years ago). Noticed on a ride yesterday that I was getting some weird motion out of my 2-piece brake rotor in the rear. When I hold the brake and rock the bike fore and aft, there is motion in the rivets where the braking surface joins with the hub. My current setup is I have magura MT trail brakes with the two piece rotors. I have a 4 pot front caliper and 2 pot rear. Stopping power is good, but I can't lock up the rear. I'm running 4 pot front and 2 pot rear brakes, 180mm discs. I will be honest and say I "experimented' with some knock-off Hopes and I am probably paying the price. Curious if it might have something to do with the rotors?
Are the Hope rotors worth 70 bucks? Should I be running a one piece rotor? Is the little bit of "rock" that happens on the rivets of a two piece rotor normal? I've never noticed it before...so I think the rotor is ready to be replaced, but maybe not?
What is your favorite rotor and why?
