The Good: rotors stay clean includes mounting hardware
The Bad: Heavy draggy feeling
These came stock with Hayes brakes on a complete bike and came off quickly.
Even with all the cut-outs these are HEAVY rotors. From the start these brakes felt draggy and only really slowed when I was clamping down hard. Thought maybe is was just break in and gave them some time, but it never got any better. Switched out the Hayes Light Weights and finally got some good brake feeling.
Still have these rotors, but I think they become a clock or someover cool looking wall art.
