I have a 1986(?) Ironman Master, Yellow and White, with 600 components, first gen 6207 series.
Really love the ride and the brakes were better than the old 105 I have on another bike, but going down a steep hill was a little harrowing squeezing the life out of the levers.
The brakes have the recessed nut. Can I put modern 105 calipers on the frame? Or any other with recessed nut? I dont want to mess around going down hills and I liked the 105s I had on a Domane (dont have anymore).
I have 8 speed Sora brifters on the bike now to drive the calipers.
