Sorry about that. I'll take the advice to move up to 25s. If I recall correctly some 23s run big and some 25s run small and they can sometimes be physically the exact same size.
Now if I can remember how Rival works and how clipless pedals work I'll be on my way. I just need to let out my heart rate monitor belt a few inches before I start.
Funny! Good to see you back!
Regarding weight, I have old farts of my age group (probably a lot older than you) who weigh about 230 and ride their collectible Raleigh Professionals and 753 Carlton Works frames on collectible spoked tubular wheels shod with old 21 mm tubulars that look like the ones I quit repairing in college. They get a puncture or two from time to time, but those bikes and wheels are old and still going strong. I think if you don't jump curbs, bomb off-road, or ride through potholes you should be fine. But a fatter tire will be more comfy and give you more margin of rim protection.
