I just read a comment on a bike review that piqued my curiosity: "20 and 24 spoke wheels seldom need maintenance but when they do it will be beyond the reach of most home mechanics." I have trued (or more accurately sorta trued) the wheels on an old beater bike and assumed I would be able to do so on my Tricross Comp when the time comes. I am glad to hear that the time may not come fast but what is with the difficulty issue? Are these things really a lot more difficult to true? Do the spokes tend to stay in place for a long time?
