SO with that in mind WHY oh WHY do so many people want to do it? If you only want one derailer, why would you want to run 3 in the front instead of 6, 7, 8, 9, or 10 in the back? Simplicity is always cited, but rear only is clearly simpler than a front only with the rear left on for chain tension. I don't get it? why do people seem to think the front derailer is perferable to the rear? WHY oh WHY?!!!! Someone please tell me!!

ok i feel better now
