Hi, I'm converting my old Fuji Special Road racer frame into a winter fixed gear machine. Its been gathering dust for too long, and I'm afraid to lock up my shiny new track bike outside. I'm building it with the rear wheel brakeless, but since I'll be using it in snow and ice through downtown traffic, I want to put a disc brake on the front wheel. I've managed to find a 700c front wheel with a 160mm disc brake rotor and a small shimano deore hydraulic disc brake and lever. What I need to figure out is what mounting adapter(s) I need to connect the disc brake to my fork.

My fork has an eyelet for fenders, like this fork: http://parts.spicercycles.com/site/images/library/catalogs/soc/prodl/FK0801.jpg

and I would like to make it like this: http://www.fixedgeargallery.com/2004/c/olsson2.jpg

Any help is greatly appeciated!
 
A road fork would not be designed to take the sorts of stresses a disc brake can put on it.. whether it'd actually see such extreme stresses in a road bicycling application I'm not sure.

Personally I'd be hunting around for a 700c fork that has the disc tabs built into it. Take a look at cyclocross forks, some of them will have disc tabs.

The front wheel is somewhere you really don't want to take any chances.
 
I ended up buying a dimension 700c threadless rigid steel disc fork. Unfortunately its black and doesn't look nearly as cool as my last fork (no chromed fork crown or two tone painting). My last fork was threaded too meaning I needed to get a new headset and stem as well. I do however plan on putting this bike through a fair amount of abuse, so in the end safety and durability are the the most important. It should still look pretty sweet regardless though! I'll post a picture once I have everything assembled.
