I found a 1991 Miyata Elevation 300 (assumption based on bright yellow color and a quick Google search) for $49. The seat-tube says "splined" "triple butted" and I think something indicating that the tubing is specific to Miyata. The RD is Exage 300 XL and the crankset is something unreadable and XL. It's not the large size I would prefer but I've ridden smaller bikes in the past. I am primarily interested in the frameset to build up a fat-tire neighborhood bike. I prefer a more sporty geometry but I know nothing about this particular bike.
