I am about to order a custom steel frame and would like to go foco. I read one post recently that said foco tubes are so thin you could dent the tube by squeezing it with your hand! Is this so and is 853 the same or is it similar in this regard? The builder says that he builds foco frames for 200 pounders but I have not been able to get through to him about this.

I have seen/lifted Foco tubed bikes. Yes, they are super light. I got a chance to ride one of the new Cervelos made out of Foco. It rode like a dream. However, I also got a chance to squeeze the tubes. I know the trend is towards ultrathin-walled bikes, but this was scary. The concern I have heard about Foco is that it doesn't stand up too well to wear and tear. Scratches/paint chips become causes for concern. Not a problem in some parts of the country, but not something you want to worry about it in parts of the country with less than ideal road surfaces. I have also heard of frames rusting from the inside out (but that might be isolated cases due to poor treatment of the tubing). As for 853, it is also thin and lightweight, and like Foco, apparently gets stronger when it is brazed. I have also heard (again, isolated anecdotes) of rust problems with specific brands, but those (again) seem to be a function of poor rustproofing. My biggest concern with the ultralightweight (thin walled) batch of steel tubing is more with it being put together the wrong way and wear and tear on delicate surfaces (i.e. I am not that concerned about catastrophic failure of the frame).
Thanks for the heads up....n.m.AD14
