i've never really been able to install a set of drop bars in a quill stem (standard size with a non-removable face) without getting at least some minor scratching on them.

it's never been an issue, as i've always just taped the bar up and everything has looked good, but i'm going to install a track bar which will be untaped, except for the lower drops, and i want it to look clean.

i figure the opening on the stem has to be pryed open somewhat, but what's the best way to do this and how much is it safe to pry open?

thanks!
