Back story: I need the bike to fit in a bike locker. This bike is huge but will fit with the handle bars dropped. Rather than loosening the stem/handle bar hex nuts everyday. I'd like a quick release.

Has anyone had experience with aftermarket stem quick release with the rad runner? What part(s) worked and where did you get it?

Here is an example of what I'm thinking will work if I can find the correct dimensions: https://www.screencast.com/t/9i83g4Fu

50 mm + 30? (15 mm rise)
