Roadie sizing help?

Yeah, I know, fit is it… but I am looking at an online deal, not sure if I can get to ride one (and I bought my tri bike online), so bear with me. I am willing to risk at the price/component level\

Used to ride a 60 cm trek roadie, now ride a 57 Litespeed tri bike. roadies avail. are 58 (XL) and 61 (XXL). I assume 61, but…
I stand 6’2"

Here is current geometry on my Tri Bike
GEOMETRY Size 57 Top Tube Length (cm) 56.0 Seat Tube Length (cm) 57.0 Head Tube Length (cm) 13.0

Roadies:
XL has a seat tube of 58, top tube of 57, head tube 18.
XXL has a 61 seat tube, top tube of 59, head tube 20
thoughts??? or do these numbers make no sense…
