I'm playing around with my handlebar height. A sore back has me trying to raise the handlebars. The bike was built with a 10mm spacer both below and above the stem. This is an older picture with the original installation.
I removed the stem and removed the spacer that was above the stem and put it together with the lower spacer.
The top of the stem is about 3 or 4mm higher than the top of the tube. To make it fit below the top-of-the-tube, I really should use a 5mm spacer.
Can I ride the bike with the stem a few mm above the tube?
