PM caliper adaptors

chili85

I have post mount brakes that are using a IS adaptor for my current forks.

I am ordering new forks with post mounts. As the IS adaptor will be no longer needed, do i need to replace it with a post to post one to keep the same size disc or will it just be a straight bolt on job?

Thanks

maybe maybe not, it all depends on what you have and what the fork is and what the disc size is.

MORE INFO NEEDED.

ok,

Current fork suntour raidon lod
tektro auriga comp brakes 180 disc with IS adaptor A (F180 R160)

New fork Rockshox dual air 2011 150mm qr9mm

Anything else you need to know?

nicklouse

well I am going to guess the RS fork is not one with the 8'" Post mount (you missed out which fork) so you will need a PM 160 to PM 180 adaptor.

I know not of such things :?

So i'll order an adaptor with it. Thanks for your help.

It appear you're adding 30-50mm travel/C-A height with those forks - are you sure you want to do that?

The forks i have are 140mm raidons and have a huge axle to crown length hence the travel increase to account for it.

Yes those.

I know what you mean, i did question it myself but they are 140mm on my bike and the a-c is something like 540
