Poor Design, Warps Easily

Purchased 2 of these for a new bike build, one was warped right out of the packaging and needed to be straightened in order to get my brake caliper centered, but due to the riveted design of the 2 pieces, there must not be adequate heat transfer and the rotors will warp throughout riding sessions. Sometimes the audible rub lasts until the rotor cools off a little, but it commonly requires straightening after a riding session. I can’t recommend these and wish I would have went with a one-piece design rotor.
