Hardly ever change a tube. It's actually more hassle, more often than not, because unlike fixing a puncture it requires removing the wheel, which on a fixie with no QR is a hassle you avoid if possible. Usually I can locate the hole fairly quickly - either by the shard sticking in the tyre, or by part-inflating and listening carefully all around the rim till I hear hiss - then pop off a foot or so of tyre, pull out a foot or so of tube, part-inflate, fix the puncture, feel around inside the tyre and remove anything which didn't ought to be there, then push the tube back in, followed by the tyre, then re-inflate fully. On a good day, five minutes or less, seldom more than 10.
