I leaned my fixie up against the wall for two seconds while I was getting other stuff out of my car, and turned around just in time to see it fall over and have the beautiful Nitto Northroad bars I had been savingr for such a project for the past year get wedged under the top tube, to the point I had to loosen them and pivot them down to get them out from under the top tube. Left 4 pretty big dents in the end of the bar. I was kinda surprised they dented so easily, and really pissed because I JUST taped the bar and have had one frickin ride on it.
