I'm back from a fish taco eating and beer drinking marathon in Mexico. I did manage to cut the first finger nail on the 38.1 mm down tube, but that's about all. The tube weighs 292 gms., not the advertized 304 gms. That's a fair amount for an S3 tube. I also recieved the drop outs from Paragon while I was away. They weighed in at 94 gms. a pair.
