Depends on the bike.
On some bikes you can simply readjust the brake pads downward and you're good-to-go.
Sometimes you need to replace the original calipers with long reach calipers.
Bikes that were originally designed with a lot of tire and fender clearance won't work.
The easiest and most reliable thing is to find someone who has a bike with 700c wheels and trial fit them.
