I'm not really worried about the little extra weight. if I did this obviously it would be on a fixed/fixed hub. I don't think it would strip because it's not like pedalling backwards will strip it, right? I am intrigued about experiencing the sensation of driving with a chainring in either side, (what if it is sweet?) Red loctite definitely will be involved if it happens. I would love to hear back about opinions about the stability of the two rear cogs and lockrings, if it is a track hub why would it be a problem?
