I've got a set of Avid Elixir 3 disc brakes. Currently have 160 front rotor.
I am getting new wheels that use shimano centrelock discs and figure I will upsize to a 180mm front rotor.
It all seems so confusing what adaptor I need to buy to convert the Elixirs from 160 to 180.
Can anyone please advise what adaptor I need. Thanks for the help.
Depends on the brake mount on our fork but Superstar have a great guide [url= http://superstar.tibolts.co.uk/product_info.php?cPath=57&products_id=359 ]here.[/url]
Elixir 3 are Post Mount brakes. You need an adapter which adds 20mm to your current mounting system.If your forks are Post mount (ie the threaded holes for the brake mounts come out of the back of the fork in line with the frame ) you need a PM-PM F180.
If the brake mount is side to side, perpendicular to the frame, they are IS mount, in which case you need PM-IS F180
With Avid brake mounting you have a stack of shims and cup washers. Remember how they sit in relation to the mount. You probably actually need a 183mm rotor, in order for your pads to contact all of the braking surface, but I stand to be corrected.
Sorry. I should have mentioned. My forks are post mount.
Pretty sure this is what I need.

The 20mm PM - 180 PM Front/160 PM Rear
Or the PM-PM F180 as mentioned in the post above. Either should do the job. I hope.
Just finished lashing a FS together. I say [i]lashing[/i] because of the hassle in mounting the front brake.
Post mount fork (DT XMC130) with 183mm Avid G3 rotor & Jucy7 caliper. I presumed what I'd need was a +20mm PM-PM but had to stack out with washers to get it on. Guessing I need the +40mm PM-PM. What happens if I need a 203mm rotor...? A +60mm adapter...????
What a bloody farce.
It's an Avid adapter. Pretty sure it's on the right way, because of the recess on the back.
Anyone ?

Are you absolutely, totally, completely sure that adaptor is the right way up?
With Avid calipers you need the tri-align washers to space things correctly.
Something looks weird with the post mount on those forks.
I thought the top post was normally the long post. See image below of it works??
In your picture, it looks like the bottom post is longer??

Hopefully the picture worked.
ok . further to my last post, i have been looking and there seem to be many forks with longer upper posts. But many others have longer lower posts.
what's up with that?!?
that would put the caliper on a different angle to the rotor.
the standard avid 180 adaptors are thicker at the top. so if the top post is longer (like on my manitou forks), then the avid adaptor will increase the caliper angle. But if the forks have a shorter top post (like takiswa2's photo), then the avid adaptor will straighten up the brake caliper.
makes no sense to me.
The angle to the rotor isn't necessarily critical. I ran a Hayes Stroker on a PM fork simply using two ten mm spacers and longer bolts. As long as the braking surface runs through the caliper body and the pads connect with the braking surface it should do it.
But having looked at that photo, I'd try the adapter the other way up just to make sure.
Thanks for replies (& apologies to the OP for the hijack...) :wink:.
Tried the adapter the other way up but caliper rubs on the OD of the rotor. Plus it tlooks like the adapter is shaped to macth the Juicy caliper, & the back has a recess to give more clearance for the rotor. Its all working fine, just looks a bodge thats all. 😕
No problem takiswa2. You're asking the same sorts of questions I need Answers for.
From reading a whole lot of avid service guides, I think the 20mm adaptor u have is Actually for a 180mm rotor (like what I am setting up). But u r using a 183 rotor so maybe that messes things up a bit?
