I'm amazed by the number of people who ride road bikes, often a fair distance form home, and have little to know knowledge of how to fix or adjust their bike.

So what is the minimal level of comptence that every rider should have when it comes to repairs?

Edit: darn it, computer dumped Bike Forums as I was trying to add the Poll.

So is it 1) None (I ride supported at least by my cell phone and significant other), 2) at least be able to fix a flat, 3) fix a flat, and tune a derailleur, 4) That plus change a cassette, 5) replace a broken spoke, true a wheel, 6) adjust bb's and headsets, 7, build a bike from the ground up?

[And what is the minimal competency requirements for posting on BF: Start a thread and be able to include a poll?]
