I like the dirt drop stems to get the bars up to seat level. Fitness dictates my time on the drops at my age of late 60s. Even when I’m feeling good late in the year, it will be maybe 25% of the ride, and then only on straight sections. Neck fatigue is a limiting factor. Considering your seat position comments, I find that to be one area that I keep the same measurement within maybe a 10mm range. I drop a plumb bob from the nose of the seat and measure how far it is behind the bottom bracket. All my fitting starts there. Seat too far forward has me falling forward and pedaling down like a mad racer. Too far back is like a recumbent and pedaling forward. Too far back is the only one where I had knee pain. I found the position I liked and everything else is based on that. It took me awhile to discover this concept. Nice bike and my current build is getting a 30-42-46.
