help with vintage road tubulars

hi all, im looking to build up a nice set of tubulars for racing come spring. ideally id like to use chris king r45 hubs. im wondering if anyone has experience with some older/vintage (1980's ish) tubular rims. i have found a guy with nice unused older rims from brands like super champion, wolber, and mavic. im trying to use some of these older lightweight rims instead of mavic reflexes- partially because the older ones come in 24/28 hole drillings.

are the rims strong (they weigh like 100 grams less than modern reflexes etc), can you actually brake with them, are theyre any other issues? id love to pull the trigger asap as i have the wheelbilding bug but i dont know anyone with experience. thanks.

"Vintage" rims are perfectly strong when you use enough spokes. But they don't work well with "modern" low spoke counts, unless you're 120 pounds and ride only on perfectly surfaced roads. There's a reason why modern low spoke count rims weigh so much more.

im thinking 24 hole 2x front 3x rear with some super champion performance rims. i ride 28 hole 2 cross on my king/dt set now. im 145 lbs and this will be a race ONLY wheelset. would an older 24 hole rim be strong or should i just do 28?

I'd be surprised to find those older rims in 24h. Back in the day 28, 32 & 36 were common. At 170-175, I raced on 32h tubulars all the time without issue.
24 is probably ok at your weight.

I once borrowed a pair of 280 gram rims with 28 holes. At my 167 pounds, they were dangerous. I could feel and see them flex. The minimum, for me, were 330s with 32 spokes.

The only time I saw 280 gram rims in use with 24 spokes was for little tiny guys with a special set of TT wheels.

Frankly, it doesn't make any sense to me to risk it. How much faster do you really think you'll be with 24 spokes vs. 28?

BTW, re. the braking question: They work just fine. I don't think a person can stop any faster with modern rims vs. vintage ones. The only real difference is that the machined brake surfaces of modern rims get rid of the "bump" at the joint. If you're used to modern rims, feeling that "bump" while braking can get your attention. Those of us who are used to vintage rims, however, have learned to ignore it. It has no practical effect.

If I were you, I'd think about ditching the idea of 24 holes and just get some Ambrosio F20s with 28 holes. That should result in a wheelset that lasts.
