The ID of the seat post tube appears to be 25mm (couldn't find my calipers). The OD appears to be 32mm.
Nice eye on the tape. It's Benotto. With a bit of heat, I had enough to cover one side of the bars. I snipped a piece off and with some minor surgery, added it to the shorter piece and was able to cover that side as well. As you noted, it's almost a perfect match for the paint.
I'm thinking the same thing about the touch-up paint. I used some Meguire's 105 cut to bring back the color and it's coming along nicely. I'm going to leave it with battle scars.
As for the tires, any recommendations? I don't want to break the bank on this one but I'd like to avoid cheapo Kendas as well.
Thanks to all for the feedback.
