Mine has the "standard" drop-outs, because I didn't want to
buy another wheelset mainly. I have a QR20 'Zocchi Z150 FR SL
on my other bike. Anyway, does anyone else have this All Mtn. 1
fork (not the AM1) on their bike, and if so why are there cautions
about using a Hayes 8" brake adaptor on it? My Z150 FR SL "does"
have the ISO mounts, whereas this All Mtn. 1 has the post mounts.
Maybe they consider the post style mounts not as strong...
I don't plan to challenge Josh Bender, on this bike anyway.

generally i personally advise against using an 8 inch (200mm) rotor on a fork that doesnt use a bolt through axel, mainly due to QR slipping issues, while the wheel wont leave the droppouts, it may have problems staying put. if your ademant on sticking with the fork, you can change your axel to a more conventional 8mm solid axel that uses nuts.

might have something to do with this ...

"standard" drop-outs
hayes has a compatibility chart on their site ... here (http://www.hayesdiscbrake.com/product_af_brackets.shtml). they also have a fork model chart you can check here (http://www.hayesdiscbrake.com/pdf/Mount_Bracket_Chart_2005.pdf).

Thanks for the replies. I've been using the 8" (203mm) rotors front & rear now for 2 years w/o a problem, BUT all my other forks were Marzocchi ISO mounts vs. this "post" style. Is it considered weaker? Looks like Manitou would've changed to the ISO years ago if that was the case...

The Hayes Disc Brake Adapter allows you to use an 8” rotor on 74mm post mount forks with a 74mm Hayes Caliper. Part # 98-15072

Bracket Size: 8"

Fork Axle Size: 20mm (This is what concerns me)

$16.98/ea.

I suppose they'll still work on a Standard D/O, but they just don't advise it, right?

correct, it's a liability thing. You could forget to thighten the skewer enough and the wheel could come out of the dropouts.
