Would anyone here forgo the ability to run gears, and buy a bike with horizontal(bmx style) drop-outs, so that you can adjust the chaintension without having anything(like a derailleur) hanging down in harms way. It could also eliminate the annoying chainslap and derailleur banging against the stay. I know it's not rulebook friendly, but this is more of a poll, not a serious question. Just post your two cents on this issue if you have a few moments to spare. Also, I know there are issues with this style of set-up too, like the ever annoying rear wheel moving in the drops, but it could be a viable trade-off for me.
