Was looking for some stats on my Roker today when I found a 54 cm Roker on Ebay used for $1400 or $1450 forget which. That seems to be a great price to me.

It sure is (I noticed that eBay listing also), but 54 is certainly too small for me! Trying to figure out places to find bikes for test rides but few opportunities and a full schedule, this past weekend was booked so maybe next...

The Roker Comp is a great bike and I love mine a lot. But you said "race bike" and I think that might mean that the Roker is not quite for you.
The two issues I see are the geometry and the groupset. 

The first thing to consider is geometry. The Roker has a 440mm chainstay length, a fairly slack head tube, and a lot of stack. That makes it a great bike for a long comfortable ride on gravel roads. But it's not exactly racey. 
The Salsa Warbird or the Jamis Renegade aren't really all that much different, but they lean more towards the fast and race-like than the Roker. They don't have as much headtube and stack at least, and will give you a faster position for sure.  (Also look at Noble bikes. The guy who designed the Roker is doing those. But I think they're 1x only, so maybe not?)

And then there's drivetrain/groupset. I love my 1x group. Love. But it's not really race appropriate. Go read Guitar Ted's rants against 1x. (Sorry, GT - it's a rant. But you're not wrong.) You don't get as wide of a gear range. You get bigger hops between gears. I am totally happy with 1x for myself. If it's a >10% grade hill I'll probably be walking it if it's longer than 100 yards. And I'm okay with that. And on the downhills I'm perfectly happy coasting at 30mph - I don't need to pedal to get the last little bit of speed out of my downhill run. 
But if you're going to be racing on anything other than practically level gravel, you're going to want the range of gears that 2x gives you. Hopping off to trudge up the side of the road while getting passed by people is not cool. And you're going to want the efficiency of being able to pick the gear to get you just the right cadence. 

Geometry and 1x drivetrain make the Roker Comp a poor choice for gravel racing?  What do you consider “race” geometry on a gravel bike and what are the advantages?  I consider a slightly taller stack height to be a good thing when it comes to all-day comfort and speed.  It seems like most people negate any perceived or real benefit of a short stack height by putting 40mm of spacers under the stem anyway.  I also consider a relatively slack head angle and longer chainstays to be a good thing for a gavel race bike, i.e. stability and predictable steering/handling on fast gravel descents.  I don’t need or want my gravel bike to handle like a crit racer.

1x vs 2x?  Different strokes for different folks.  Either is fine for gravel racing and 1x has plenty of range.  My previous gravel bike was 2x (30/42 x 11-34) and I prefer my current 1x setup (40 x 11-46) in nearly every situation.  I believe all the Dirty Kanza winners were on 1x this year—that must count for something.

I really don't know what a race bike is suppose to feel like. I come to this gravel riding with a cheapo Schwinn mt. bike that probably weighed about 30 lbs. I started out witht he 2016 Raleigh Tamland 1 because of the killer price and not sure if I would luv gravel riding or not. It weighed 25 lbs and if only riding in Kansas and that area it would be great. For the massive hills here on the East Coast it is too heavy for me. I will also admit that I am out of shape so that plays in it some. At my end I plan on riding some longer rides over 100+ miles so the Roker works for me. What I really dislike at bout my Roker is the 1x but maybe that is just me. My last ride/race kind of confirmed this to me. We were riding on a rails n trails road. We weren't going that fast but I was shifting my gears all over the place to try and stay the same speed as him. I would guess that the bottom 4-5 gears has too much jump and gaps in them. You could get the Sport that has the 2x and only weighs 2 1/2 lbs more. Had I had it to do over that is what I probably would have done. Good luck

If it was easy it wouldn't be a memory. You just hope you don't have all your memories in the same ride. been there dun that Zman
