I understand your misconstruation of my post Shecky. Please allow me to explain what I said a little more in depth:

I do wheel-truing and chain maintainence not because it is a fixed-gear, but because I ride in a dense, urban environment. Riding over pot-holes every day can put your wheel out of true pretty easily whether your bike be geared, single-speed, or fixed. As for the chain, when one rides in a city you'll definitely get grit in your chain which needs to be cleaned out regularly. With regards to tensioning the chain monthly, there are two reasons for this: First, when you take your wheels off to true them you need to retension the chain as you put the rear wheel back on. Second, by putting a lot of torque on your chain (starting and stopping with it) it'll naturally get stretched out a little faster than a geared/ss chain might. Therefore you should retension your chain and replace it about once per year on a FG bike.

I hope you can see that this routine maintainence has very little to do with the fact that I ride a fixed-gear and has more to do with my love of my bicycle and my desire to have it last until the end of time. In fact, if you ride a geared bicycle in the city you'd probably have to do maintainence in ADDITION to what I do (including derailleur maintainence and brake systems) to have it last just as long.

As for trusting my bicycle? With a little bit of maintainence, I trust my bicycle completely.
