Hey so yeah, I've been flipping (ok hoarding) vintage bikes for a few years now and I'm ready for a fixie conversion. Out of my herd I have a few bikes that I could use, but some help from the been there done that crowd would be awesome.

So, here are the options:

1) 1988 Cannondale SR500 Criterium
2) 1987 Trek 560 EX Pro
3) 1986 Miyata 710
4) 1990 Miyata Carbon Tech 3000

The Cannondale and the Trek are awesome riders but hurting cosmetically, the Cannys paint is hurting and the Trek has a small ding in the top tube.
The Miyata 710 is awesome but I have racier race bikes and comfyer sporting bikes.
The Carbon Tech Miyata has a Carbon wrapped aluminum main triangle and aluminum fork and stays. It's in great shape and rides fine, by the RX-100 group it came with is a cost concession group. Also it would be a very unique build.

Thanks!
