The power of a better fit?
Hi all. Have had my road bike for about a month now and have been doing some reading and tweaking to try and get a good fit. Some things I've been looking at have made me think my seat was a little low so I bumped it up about 1.5 cm. Went out for my usual ~15mi ride previously I avg about 13mph on that ride with a cadence in the low 70s usually relying on the middle ring of my triple. Today after the seat post raise I avgd 16mph
And was consistently spinning at 80, predominantly on the big ring. I don't think less than a month of riding with less than 150miles under my belt accounts for the leap in speed. Is this the power of a better fit? Also, coincidentally I felt like I wanted to stretch out more and was regretting swapping out my 120 stem for a 90. Should I go back to the 120? Flip my 90? Thoughts on any of this welcome.
