Possible to Mount a 2005 180mm Louise FR

66 post mount is a 160 direct, totem is 203 direct.
you have a short arm caliper with the #3 adaptor now to fit the 66, if you put that on the Totem you would need a 223 rotor? (or is my math way off??)

they just don't make a IS to PM adaptor that works with 203 post mounts, they make one for short arm to 160 mounts for 210 rotors, but that doesn't help either.

I found it was easier to get a complete set of brakes. You could buy one new PM style louise caliper and a 203 rotor, pricey, and then you would have different pads front and rear also. Your juicys will need a 203 rotor also.

Whats interesting is the pros are saying the newest Avid brakes are too powerful so they are running 160 rotors, with the Totems you are limited to 203 and up...

Thanks, I may call Magura Tomorrow to Confirm.

I probably will just move the Juicy 7s from my SS and get an 8' rotor & adadptor for the front. I really like my 05 Louise Frs better than the 07 Juicys.

they've had plenty of practice answering that question .
the old IS louise has too long of legs, in fact any IS brake caliper is not going to work with 203 direct post mounts.

the totem is a 203 direct mount, no adaptor needed with the juicy, just a 203 rotor.

Stupid Question, but I think I may have a PM caliper

I originally purchased these brakes for my my manitou firefly and then got an adapter to run on the 2005 AM1 and then a different adapter for my 07 66 SL ATA.

couple ways to ID your caliper, measure the distance between the holes, and are the mounting holes parallel with the rotor.

Also, if you remove the adaptors from your louise can it be bolted directly to the fork mounts, i.e. do the holes line up?

I have always assumed there was no magura louise post mount caliper before the latest version.
