a little question..about fork...
what's the difference between the 51mm and 74mm on the brake boss like the manitou? I have a set of hayes nine using a 03 Manitou skrabe elite... I'm considering getting a new fork... either fox or rockshox.. but they have all 51mm brake boss. Any problem installing it? thanks

People can say what they want, but the "Bottom Line" is that Manitou didn't want to join in any "Standardized" games....
They chose to be different, and lost alot of customers (me for one) in the process....

Shimano Certified
The 74mm 'post mount' is designed to the same parameters as the shimano and hayes design calipers. Originally there were frames that came with 74mm rears as well. From a stress standpoint the post mount is marginally stronger, not that the ultimate strength of either was ever an issue. The post mount calipers tend to be stiffer too, as the lateral adjustment is by the mount bolts themselves and not an adjuster in the body. The good news is the calipers can adapt from 74 to 51 easily.
A 51mm brake cannot however cross the other way, as the holes are 90 deg from the desired face. There is an adapter made by Hayes(likely some others) that adapts the flat face of the 74mm post calipers to the 51 mm mount plate that faces 90 deg from them. These adapters are usually relatively cheap(8-10 bucks).
