I'm not knocking steel (I ride steel) or the capabilities of square taper. There is better technology out there, and square taper is old. SSP, DA, Sugino, Campy, etc all make great products and are still superior than 90% of the track offerings. Don't take my statements as I'm downplaying square taper cranksets... I'm just defending Omniums and the emergence of newer breakthroughs in the cycling world. I've ran 75's and outbearing cups are extremely stiff. If your's blew out or something happened, it's probably a defect.
