i think they're the Superlaggera. can anyone confirm this? anyone know what the possible offset on these rims would be? i think they weigh in around 14.6lbs each (w/o tires).

seller responded back saying that they're F1's, but that's about it, and that the tires are no good...yeah, i don't think any F1 rims are light enough for my taste. i think they're all above 20 lbs.
