Review by PQuincy

Excellent replacement for noisy SRAM discs
by PQuincy

I have had a lot of noise with SRAM disks on my road bike -- I'm a big guy and we have pretty steep descents around here -- and my local shop recommended trying the Shimano Freeza discs to improve heat management and to run quieter. And they do. Not only that, they are a better value than the SRAM layered discs, too, so what's not to love?

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.

Excellent rotor as always from Shimano. Appreciate the little refinements to reduce weight.
