Question Shimano Deore Disc Post Motor Mount

...whow, say that 10 times fast... don't know why I put "motor" in the title...

Ok, I'm at work so I gotta make it fast:
I just got my Jenson order which included the 2008 Fox Talas 32 RLC. It has a post mount setup and it seems as though my OG/OE Deore (BR-M555) front disc brake is not post mount.
Anyone know if an adapter exists for this? I was looking online at some but have no idea what's what.

BTW, the re-born Rocky Mountain ETSX-70 is shaping up to be one sweet rig. Pics will come in time....

i'm pretty sure you can buy new brake adaptors that convert from tab mounts to post mounts

If the br-m555 is the 4 piston brake you can buy an adapter from universal cycles, is this what it looks like? This is what the adapter looks like for my 4 piston for an 8 inch rotor on the post mount 888. Heres the link for universal cycles, http://www.universalcycles.com/shopp...69&category=31
If they dont have it call shimano directly, they are really helpful and should have whatever adapter you need.

if not, i have a couple of hope adapters here. but it has to go to a 7" rotor. 185mm. there isn't one that keeps it at 6". or as posted above you can get the 8" one.

Brief update in case anyone else ever encounters similar prob-
The inital adapter didn't work, so I "rush ordered" another adapter and rotor from Jenson that they "promised" would work. Alas, it didn't work either.

Called Shimano (admittedly should have done this first) and they also "promised" that yet another adapter would work (Y81737000) but with a 180 mm rotor. Neither item seemed very easily available in a reasonable time frame in this corner of the world...

I started thinking about it--those old brakes were 3-4ish years old (lots of hard riding too) and had NEVER been serviced. Being a bit of a computer dork, the analogy came to mind that I was trying to install the "latest and greatest microsoft operating system" on an old-school, worn-out computer. It is possible, but chances are you will need to upgrade/change all sorts of stuff and the performance just won't be there. And it'll be a "band-aid" solution and you'll be upgrading sooner than later whether you like it or not.

Long story short I purchased a set of 2007 Avid Juicy 7's from BlueSkyCycling online. Went with 160 mm rotors for now. Figured I can upgrade to a bigger rotor later. Let's just hope I don't need another adapter....
Man, I just wanna ride my bike!
