Hi all - new here so hopefully this is in the right forum. I am searching for a new bike and I need a higher stack/lower reach (read: endurance) bike. However, I’m also considering sizing down. I have always ridden size 58 (my previous bike was a Synapse and my current bike is a Giant TCR), but my bike always feels a little big and I’ve had to decrease my stem length to 80 mm or so. I figured I’d check here whether there are any downsides to choosing a smaller frame size. I am 74 inches tall with a 34.5 inch inseam for reference.

thanks!
