I've been a long time lurker, first time poster on this thread. Very into BMX and know a lot about the 20 inch world but not a lot about road bikes. I have a vintage tamara fork/frame that is a fixie used to commute to college. A friend of mine gave me a nice carbon fiber fork, what all needs to be in order to run the new fork on the old frame, if its at all possible.

I do know the steerer tube on the fork has to be long enough, which it is, what about head tube size. guuuuhhhh I don't want to have to learn bike mechanics for a third type of bike.

your bike has a 1 inch headtube. you need to make sure the fork is 1 inch as well. there's a strong possibility that it's 1 1/8", in which case it won't work. assuming the the fork is 1", you'll need a new threadless headset and stem to replace the threaded ones on your bike. also the steering tube on the carbon fork will need to be a couple inches longer than your headtube in order for you to have room to put the stem on.

bottom line is that it will likely be far more effort and money to put that carbon fork on than it will be worth. also it'll look weird having a carbon fork on a vintage steel bike. my advice: just keep what you've got, sell the fork and put the money into other upgrades.
