Chaser New 6-ULTRA G2 Ultralight Center Lock Disc Brake Discs Road Bike Gravel Disc Brake Disc 160/140mm Without Locking Cover

I have a thousand mi or so on them, the cheap ones that are 25 bucks or so. No issues compared to stock Campy rotors (I'm running Wheeltop Tx with Campy calipers). My setup is centerlock, but I'm using 3rd party adaptors as they're lighter than the built in centerlock options. No improvement either, other than they weigh about the same as the lighter Campy rotors for much less $$ and have some bling factor. The main difference between these and the lighter units (ie Carbon Ti, chaser) is that the "floating" buttons on the cheap ones are ss whereas the expensive ones use ti. So there's a few grams in weight difference.
