Stuck stem adapter
I just converted my 1" cannondale steerer to 1 1/8" with a nashbar adapter but I forgot to put grease on it when putting it in and now it is stuck. I can completely remove he bolt but it won't budge. It went in just font though. Should I try heating the metal with a heat gun to loosen it, or is this best handled by the lbs? I like the height currently, but I want the ability to adjust it. Thanks y'all!
