My Avid Juicy 7's have been rebuilt and they still leak. Any how I have new rotors that are 185/165mm. I am looking into Formula K24's and there's a set on sale but they don't come with rotors and are set for 160mm rotors.

The question is can I use Avid adapters for 185mm/165mm Avid rotors? I have used adapters before with my Hope's that were set for 183mm and the rotors were 180mm so the pads didn't make full contact. I don't want to repeat that.

There are 2 things that can be done. One is file approx 2-3mm off the Avid adapters, or Two, buy the new correct adapters.

I switched out my 185 Avid rotors for some 180mm rotors. The front bracket I was able to file off the proper amount and make it work great. The rear I ended up messing up the bracket and took too much off. I had to buy a new bracket to use on the rear.

I've been using this combo for over a year now.

I think you got it backwards. I am going to run the 185mm rotor in the front not 180mm rotor from Formula. I have the mounts for the 185mm from Avid and wondered if they would position the Formula brake to work with the 185mm rotor. I am not going to file and I know that I can buy new adapters. What I want to know is if I can run the adapters I already have?

Or 3, use your avid rotors with the Formulas.
This is what I was asking to if I could run the Avid adapters for 185mm w/ the Formula's for the Avid rotors.

Does anyone know if the Avid adapters will position the Formula caliper correctly w/ the Avid rotors?

Get a room you two.:skep: Stay on topic, this was about formula brakes using Avid adapters and rotors remember.

Are you sure that you're using a 165mm rotor? Avid hasn't done that in quite some years. You most likely have a 160mm rotor.

It should be able to fit fine (leave out the CPS washers as the height is compensated for by the caliper). There is an off chance that the caliper may bottom out on the adapter though.

Yep, no problem.

In fact, on one bike I'm doing the opposite: Formula adapters and rotors with Avid calipers.

Avid and Formula calipers both conform to the 74mm Post Mount standard, so the adapters are interchangeable.

Thanks this is exactly what I was looking for. I had a hunch but you proved it to be correct. I ordered the brakes and they will be here in less than a week. I will update once I get them mounted. THANKS :thumbsup:

You are probably right. Either way I got what I needed, the Avid adapters will work with the Formula brakes to fit the rotors. So as long as the rotor size and adapter size match I am in good shape. Thanks for the info.
