So, the next project.
I'm guessing 68 to 71. This would have had the plastic Simplex derailleurs that rotted and broke with exposure to UV rays. Thankfully, those had been replaced years ago with Shitmano. I got the bike in kit form and it looks like it's all there save for cables and housing. The bars with the white tape seem to be the correct ones. The rims are mismatched but the steel hoops will probably be aimed towards the recycle pile and I'll spring for a pair of 700c aluminum Sun CR 18 rims. If I wasn't doing wheels, this would be a one day kit.
Oh, yeah, the last Mercier I had, I was riding it when I got hit from behind.
