Mavic wheels in general are not designed to be servicable at your LBS. It depends on what needs to be done, obviously. One major drawback of tubeless tires is that they require the use of an air compressor to properly seat the tire initially. Not everyone has access to this, and if you have a flat you just put a tube back in. For me (IMHO, obviously) the benefits of a tubeless stystem are not sufficient to outweigh the drawbacks just yet. As was mentioned above, the Equation wheels are a solid bet at a ridiculously low price. Otherwise, Sun Ringle has some killer wheelsets as well.
