Here is the information about frame size and set-up: since you are five feet tall and five inches, get a frame that has a seat-tube length of 57cm from the center of the bottom bracket to the center of the top-tube. Then get a 60 or 80 mm Nitto Jaguar stem, no higher than 80mm.
Then get cranks that are 165mm length of arms, have a front chain-ring that has 54 teeth, and a rear Phil-wood cog that has either 17 or eighteen teeth, no lower than 17.
Then put the saddle all the way forward upon its rails and the stem slammed.
It will take some time to get used to, a bit of stretching, and you will be always in pursuit poise.

A 57 cm seat-tube will have a steer tube that will put your handle bars basically level with your front tire, making your bike more sexy.
The gigantic front chainring must by all means be doubled with a gigantic cog in the rear, so that both sprockets can flex with each other.
Plus a larger rear cog diffuses the tension on your drive-side and it is healthier for the frame.
When it comes to tires and rims without a doubt choose tubulars: they are half the weight and two times as stiff upon the road.

No one can determine that perfectly over the internet. Let alone with just height to go on. Use this to get a rough idea:

Then go to a bike shop and try some in that range.

There are so many adjustments you will need to consider, and if you don't want a Nitto Jaguar, then get this:

170cm rider on a 57cm frame? Shit I'm about 178cm and a 56cm frame is big for me. I always error on the side of small. Easier to adjust everything to your measurements on a smaller frame than one that's too big. I'd buy a 53 or 55 if I was you.

I agree with Bwillam. A size 57 is to big for a person of 170cm height. Traditional framesizing is based on seattube length. For 170cm I'd choose a 54 frame. A 57 is really to big for you. Check this or other framesizingcharts; https://www.evanscycles.com/help/bike-sizing-road

I think all frames should be made a 57. If you dont fit, too bad.

Bike fit is very specific, and nobody here can do it for you. If you're really in the dark and confused about size, id say start on a 52. Could be too big, could be too small, but probably a good place to start. you'll eventually break or sell this bike, so NBD.

Bike fitting is so important for a biker to ride safely. Before buying any bike everyone should calculate his/her frame size base on height.
If you don't know your frame size you can calculate using this
