Hello there, yes a lot of older bikes came with short seat posts. Quite a f ew of mine have needed to be jacked up with more modern and longer posts. A s long as you stay within normal insertion levels for a given seatpost you' re OK as far as I know. Maybe to compensate for the extra effort/leverage o n the ST you'd want to insert the post a little further into the ST than no rmal. Ridewise, it can be OK, it can also be bad: too high saddle for bar h eight meaning too much weight on the bars; different weight distribution: w ith a open angled ST your center of gravity will move way too far back. All this can in some rare cases lead to a light, twitchy and generally unpredi ctable front end. Push saddle as far forward on post as it will go. In extr eme cases I have reversed saddle clamps or turned saddle posts 180°, a nd modified both bar stem height and extension. In one case had to replace 38 cm bars with 42 to make a bike feel safe.

Of course, before you take any notice of this, you'll need to listen to oth er more experienced and more expert people than me. Maybe they will concur.
