30 minutes into a ride I moved my seat back about 2 mm, 45 minutes into the 3 hr 15 min ride I dropped my 110 mm stem down 2 cm and it felt great, especially on bumpy road, there was no transmission to my upper back/shoulders. Perhaps that was a result of my shoulder rounding and elbow bending...dunno.
Legs feel good too... no localized soreness in the quads. I have a feeling I'll feel it in my hammies/glutes in the next couple of days due to the position change.
I did have to keep focused on the pelvic tilt and I must say, no real discomfort to speak of...I did have a hard time getting flat though - felt hunched, not sure why (more drop? less drop? more reach? less reach?), but I'm thinking I need to go back to the 120 stem with the same drop concept...I'll experiment.
