I have 160mm rear rotor on my bike right now. I just picked up a 180mm rotor and need to find a rear adapter, but when I went to Hayes website they only have adapters for 160mm or 203mm.

Does anyone know if the adapter for the 203mm or the 160mm will work with the 180mm rotor or which adapter will work?

Will a Hayes 8" rear mount adapter work with a 7" rotor?

No

You need the correct size.

I went to Hayes website they only have adapters for 160mm or 203mm.

The Hayes website isn't the best at the moment.


Plenty of shops sell the Hayes 7" / 180mm rear adapters.

Here's a few.
