I hope this forum is a reasonable place to ask this question: what is the effect of seat tube angle on bike fit, and specifically on how much of a rider's weight lands forward onto the bars? Is the effect significant?

The reason I ask is that I have new bike that I'm trying to dial in, and I can't seem to adjust things in a way that avoids putting too much of my weight onto the bars. The bike in question has a 74-degree seat tube angle. My previous bikes have had 73 degree seat tube angles. Could that one degree be significant? Am I fighting the basic geometry of the bike that I'm trying to adjust?
