Reviews
bought these to put on a backup set of wheels so I did not have to swap rotors each time I was changing wheelsets. these seem like a good value especially when they were on sale on a deal of the day special. I wonder if anyone has received $50 for submitting a review.....
These rotors are really nicely built, they look very nice and I never worry about the rotor failing to stop me. they last a long time. I have used these since they came out and have never had any issues with them.
