For disc brakes, you need:
- Fork with disc tabs. The one I used is currently
on sale for $140.
- Disc hub. The
dynamo hub is about $80, but you can get an entry-level non-dyno front disc hub for $20.
- Disc brake & rotor. You can get the Avid BB7 for about $60, including rotor. It's mechanical. I also had to get a rotor adapter since the Shimano dynamo hub is centerlock ($20).
In addition, depending on how handy you are, you'll need to pay for some LBS labor. Rebuilding the front wheel with the new hub could be $20-$40, and they'll have to transfer some headset components to the new fork. If you have them do the whole install for you, I'd guess it would be in the $75 range.
Regarding the dynamo hub specifically, again, it involves a wheel rebuild, then there are the cable runs for the lights which aren't much more complicated than cabling for a cyclocomputer.
Happy shopping!
