Columbus Formula Two Tubing - What is it?
Sorry if this is one of those annoying and recurring subjects. I did search and read most of the old threads on this - seems mostly (all?) tied to Bianchi built frames, lots of guesses on what it is, but nothing definitive. The most comprehensive thread I came across was seven years ago and seemed to infer it was a mixed collection of SP and SL tubing? Of course, another thread claimed it was just whatever Columbus had on excess inventory.
Does anyone have a bike labeled as Formula 2, and if so, is there a noticeable ride difference between it, and say, Tenax or other "mixed" blends/tubes? Is it unique to just Bianchi?
