I'm just trying to understand how you could wear down paint.
Here are a couple of photos of my top tube on the Colnago, side view, taken in June 2014, and January 2015. I was somewhat startled by the increased wear in just the last year (this winter?).
When standing the wobble of the frame abraids somewhat on my pants.
However, I think I've concluded that the abrasion and wear is much greater when wearing rain/slicker pants than just cotton. It is extremely rare for me to be riding the bike with just hairy legs. It is possible that the rain pants also hit the frame when simply pedaling while seated.
I've finally built a Titanium "rain bike", so hopefully both wear and rust will be reduced on the Colnago. The frame will probably be used as a pattern for my first bike build from scratch and any necessary jigs to build it (other than figuring out how to do 130 or 135mm dropout spacing). Then I will decide how much restoration to do on it.
