One difficulty with converting this '80s steel warrior into a modern racebike for the present day Parallel Universe is tire clearance.
In the modern peleton, a 25 mm tire is narrow, 28 mm is common, even wider on pave. Today's carbon frames have the tire clearance for those widths.
For this frame, test fitting a 25mm (outside width) rim w/ 25mm tire (clincher) has 4mm clearance in front but only 3mm clearance w/ rear chain stays. See below. I'm likely going with tubulars, but even so I don’t think 28s will safely fit.
In theory, as I understand it, for best aero the rim max width should be at least 1.05 X the tire width. So if I'm going to run 25 mm tires, I'll be looking for rims at least 26-27mm wide just inboard of the brake tracks.
Rear about 3 mm clearance with 25 mm clincher on 25 mm rim
Front about 4 mm
