Take the spacer off, put it above the stem, and try it. No harm done.
A few years back, I raised my stem a little. I had a 1" spacer, which I decided was way too much, so I took it out. The result was a much better position for me. I didn't move the seat at all
Thanks for your insight.
I'm looking to remove about a .5 inch spacer. I read on another forum the following;
"
Yes, as you lower the bars, by flipping the stem or removing spacers, you lengthen the reach and reduce your hip angle. This reduces frontal area and thus improves aerodynamics but it lowers power by reducing the power generated on the upstroke. There is clearly a trade-off and you would need to monitor closely to see if this helps or hurts. If you have a power meter you can test indoors first to see what the impact is on your power generation then head outdoors to see how it affects your speed, and most importantly comfort, unless you are only using this setup for short races."
What I wanna do is find the optimal area between being aero and generating max power which is why I thought it's a good idea to raise seat height personally but I haven't done so yet because I'm waiting on more feedback from the experienced people here.
That's why I'm wondering if I should raise seat height or not or whether this guy has the right idea or not because as a beginner it's difficult to gauge who has the right idea on optimal fit. I guess I 'm wondering if that's true and if it's standard practice to increase seat height when you remove spacers.
