I've seen few examples of OEM's hinting at being the same as various top-of-the-line framesets. Simply unbranded. They look identical, but the weights are often several hundred grams heavier, which makes me think that the same mold is being used but the lay-up is different. Probably being paranoid, but I'm steering clear of these. I'm very tempted to get a openly taiwanese frameset though*,
'Steering clear'...LOL
