I was amazed to be at the shop of a well known bike painter/repairer and seeing the details of a lovely English bike, I think was a Holdsworth, without it's paint. It had what appeared to be wrap around seatstays, but with the paint off you could clearly see that it was just a filling in with brazing material and then a carving back out to make it appear that the seat stays wrapped around on the front of the seat lug. This brings several questions to mind for me. Are all wrap around seat lugs done this way? Is the effect purely cosmetic, rather than structural? I suppose I'm the only person around who did not know of this, but I was under the impression that there was an actual wrap around of the seat stays that contributed not only beauty, but perhaps a structural advantage. I feel like the little kid who's just peered down the stairs and seen who Santa really is!
