Proteus frame anomolies
Hi. I bought Barndoor's Proteus last summer ('08). This Proteus thread helps a lot. The frame seems to be 67 cm c-t, had/has 126 mm rear dropout spacing, brazed on shifter bosses and cable guides which suggests it may date from the early '80. The posted Proteus flier confirms what I suspected: paint is Dupont Imron. Really tough stuff...this paint job is at least 25 yrs old and holding up fairly well. That the seat tube is not Reynolds 531 seems confimed by the length (wasn't 25 1/2" or 65 cm c-t the biggest frame that could be squeezed out of Reynolds 531?). I figured something was a little odd when I discovered the seat post diameter is 26.6 mm. Bottom bracket housing also seems bomb proof--a frame built for a tall and heavy rider, I guess. Still, there is an old green, gold and black Reynolds 531 sticker at the bottom of the seat tube.
I did pull the Shimano 105 stuff and replaced it with vintage Suntour. This is a big bike, but I'm a big guy. It's a pleasure to ride. I've always had frames a little small for me.
One thing I wonder about: was there ever a Proteus head badge or decal?
