ive used both rims many times before and if only mavic made there rims wider, i dont think there would be a better rim on the market! Mavics also build REALLY well, and from my experiance grind ever better!!!, but the dx32 is my personal faveorite "wide" rim, these grind just as well as the mavic and i never have any problems building them, although i DONT think they are eyelited (is that right?), but i cant say ive found that a problem, ive got friends who run these with every other spoke missing,(32 hole rim 36 hole hub) and they still sware by this rim, look out for alex dx32 xlite phatso planet x bmf Old skool onza rim in red megamo(same rim with holes) All of the above are the SAME rim, so any of these would be fine:) to some up: d521 FANTASTIC rim, but far to thin for trials dx32, amazing rim from my experiance.
