>>2018741Go by top tube length and if you like larger frames with bigger headtubes, or shorter frames with more drop+longer stems.
The only reason to get a smaller frame is for shorter seat tube, shorter top tube, and shorter headtube. If you have a 33in inseam PBH you could probably fit up to a 58 if you wanted. However the headtube could be too tall for you then.
I am 5'11(in the morning) with a 34.5in inseam and can fit anything from a 56- 63.5. I just slam the stem on the larger frames, have less seatpost, and have a shorter stem. On the 56 I use a 120mm stem, and the 63.5 has a 58cm top tube so I use a 100mm stem. Do keep in mind the seat tube angle slackens as you get a bigger frame, so if you like to slam your seat forward on a 54 don't get a 56. I notice on my vintage steel the bigger frames I tend to run my seat further forward, and the smaller frames the reverse.
Luckily modern threadless stems allow tall risers and easy stem adjustments so the 54 or 56 will fit fine for you.
>>2018756I uhhh just used what I had laying around. I know my vintage campy aero brakes required the rounded end. While the 7 speed dt shifters required the cylinder one, but inline. Not the mtb brake style where the cylinder is perpindicular to the cable. Jagwire is good stuff
>>2018733If your seatpost tube isn't rusty I could see it work. I know with a nice QR seatpost clamp my seaposts glide well.
Never used a hiterite but I can see it being nicer then just lowering the seat and eyeballing the nose on the toptube every time.
