If anything, the reach could be a little longer. I didn't want to start changing stems until I know what position the saddle would be in. I'll ride it a bit and see how it goes.

Is there a "correct" alignment for the bum to saddle interface? Like, at what angle should the sit bones make contact, right on the tips? Sorry for the weird question, it's just something that didn't come to my attention until yesterday and now I'm wondering what is "correct".

It does help to get an outside opinion just to make sure I'm not doing something obviously wrong or if there's something important I should be aware of.

I'm considering getting a professional fitting. I hesitate because it's an old 80's Schwinn and doesn't seem like it's worth putting money into. On the other hand, I like it and want to be comfortable riding it so I suppose it's worth the investment.
