Its good to be sure when choosing a new frame especially one thats so expensive but I think you are overthinking it with all this stack and reach stuff.
Standover: 819 mm = 32.2 inches.
Whats your inseam?
Whats the standover height of your current frame?
Top tube length 550 mm
How long is the top tube on your current frame?
I asked a friend of mine what the seat tube length on his 54 bk was and he said about 57.5 center to top.
How long is the seat tube center to top on your current frame?
If your current frame fits this should be like common sense choosing a BK size.

To take it farther after doing some research on stack and reach it seems like these measurements are only necessary for tri bikes and frames with compact geo.

Stack and reach applies to all bikes. It's a reference to compare frames. Never once did I ask for assistance on helping me pic a bk frame size. Or how to size a bike in general. I really appreciate the dedication you all have for posting to bikeforums and working your way towards being professional bike fit gurus, but this is not needed here. Just fork length please if you have it. Or ATC for the OMGZ I AM SUCH A BIKE PRO I KNO ALL DA CODEZ WORDZ BUT HAV TRUBLE SPELLING BASIC WORDZ N I TYPE POINTLESS POSTZ CUZ I WANT MY NUMBERBZ TO B BIGGEST EVA.

Hey dude, you were exactly right. The frames all require a specific length of fork that is different from one another and isn't based on the wheel size or anything. What you need is a fork with ATC of 387mm. See this is the kind of help you get when you ask so politely.

Scrod...you still gonna measure your fork for this guy?
op...your statements to the effect that your preferred stack & reach measurements are the accepted industry standard & the best way to fit a bike, are way off base.
it is simply that guy's own creation & he is promoting it. after close to a decade of pushing his bike fitting program he has gotten a limited number of manufacturers/teams/fitters on board with him which indicates that it is far from the big deal that you make it out to be.

I never said it was the "standard" or the "best way to fit a bike". I did say it was a good value to compare frames, or the best way, at least to me to understand how a frame would fit if you cannot ride it 1st.
For example if I am riding a 55 kilo tt, and want to see how it will compare to a 54 bk. I can compare stack and reach.
Another example. I once used a stack and reach calculator (that also includes stem / spacers) to figure how exactly how many spacers I would need under stem my to change from a positive rise stem to a thomson 0 degree stem.
Or by having stack and reach I can figure out exactly what will change when changing from a 5 degree 100mm stem to a 10 degree 80mm stem.
That is only a few examples, but importantly its to compare frames.
I posted this thread asking for the fork length of a specific bike. That is all. Scrod said he was going to check it out when it got a chance, and that should of been it. Then I was bombarded with a bunch of nonsense about how this is all irrelevant, and that is not the correct way to fit a bike. And here is the correct way. And now it's been discovered that it only applies to tri bikes, etc. It's like everyone around here needs to prove how much they know about bikes.
I'm not a bike fitter. Never will be. Don't want to be. Don't care. I do know my body, what frames I have ridden, and what I had to do to make them comfortable. Which ways I do this, what does it matter to anyone else? Didn't mean to be a dick. Just have small tolerance when it comes to grammatically challenged people that contribute nothing and think they are funny.
Anyways, if you can still grab the fork length / ATC / Axle to crown, that would be great. If not, no worries. Bound to find it somewhere.
Thanks.

It's like joining the bloods or MS 13, the gang stomps you out for four or five minutes, if you're not in tears you're in.

Scrod, I have one of your straight-legged lugged forks in chrome on my white bareknuckle. How much of a difference is there between the 2 forks? It seems like the ATC is pretty close but the rake is about 5mm off correct? It seems to ride fine, and the look is similar.
Thanks
Thanks

The blades on the EAI forks are a little flatter/wider but the measurements are close enough where you won't feel any significant difference.

Funny to see so many of the self-appointed fitment experts totally thrown by talk about frame stack and frame reach. This is not some weird exotica but quite standard way to fit a frame and more informative than the top tube and seat tube measurements (because of different st angles and tt slopes). Then again, a lot of people have problems with difference between c-c and c-t too.

Gonna take a while for Stack n Reach to propogate through the bike world.
As mentioned earlier it has a strong foothold in the Tri crowd. It's also quite common in MTB land.
With horizontal top tube bikes like the Bareknuckle you don't really need to know ATC to calculate stack, so it's a superfluous datum in this case.

Take a bike and put a 375 fork on a bike, then put a 420 fork on that same bike. Tell me the stack doesn't change. The front end will much higher with that 2nd fork, which is a higher stack.

So you're gonna run a non-stock fork now?
The bike has a horiz. Top tube. You can use that as a reference if you plan on running the stock fork
