I’m new to the club

NJS Bridgestone 😁 seattube measures 55.5 and top tube measures 57.5. Had this old school dura ace aero seat post that I had gotten for one of my road bikes a while back but the post is 27.2 and the bike I wanted it for had a 27.0 seat tube. Seems like the clamp for this one was over tightened at some point bc the 27.2 was having a hard time going in without using a tire lever to spread the clamp opening. Might have to ream it out .05mm to get it to slide in easily. Got a set of suntour superbe pro hubs 28h that I’m gonna lace up probably to some dt swiss rims and it looks like I’ll be able to fit 28s on it. It’s not drilled, so my plan of having a ss wheelset (36h campy record front, 36h Phil 1st gen rear) isn’t gonna happen bc ss in Seattle w no brakes is asking to die. I put in a front wheel I’m building for another bike w an internal width of 22mm to check clearances. The bike should fit a rim w an internal width of 19mm w no problem.
