...have really good riding qualities, as Peugeot pretty much perfected their frame geometries to do so. That's why a lot of collectors/riders love the classic Peugeots, despite them not having the best "build quality" (sloppy brazing, thin paint,...etc.). Compared to top Italian and Japanese bicycles. One of the best riding bikes I owned was a lower mid-level model Peugeot called the PH10s I bought in 1982. It wasn't that light as it was built with Peugeot's high tensile carbon steel "house" tubing, and pretty much set up from the factory as a casual sport/light touring bike with accommodations to more vertical seating position riding with its stem mounted shifters and "safety" double brake levers. I modded it up just with lighter aluminum rimmed wheels and better brakes and the bike rode like an expensive racer, just like that. Fast, stable and stiff! That bike literally whooshed down the road with every pedal stroke! For some reason, I can't seem to get all my other bikes to do that.....
I love the looks of your Casati, it looks all business and fast. As they say, it almost looks like it's going fast, just standing still!
Bikes like your Casati and other modern bikes are so different from the 80's bikes as the "form = function" formula comes more into play. I'm sure these modern bikes ride so much better, faster and easier than my 80's bikes because of the changes.........
I actually try to avoid riding modern bikes as I had been warned by other classic bike collectors/riders that if I do so, I might give up all my old bikes and just get a modern one..... So far I have resisted the strong temptation! ;^))
