Bought this on a bit of whim.. looks like a lower end mid to late 80's Miele.

Imgur album is at https://imgur.com/a/257GA84

- Shimano 105 brakes, hubs and deraillures
- Shimano Biopace 52/42 Chainring (!)
- Tange Infinity CR-MO tapered double butted frame
- Trico Saddle
- Nitto B115 420 handlebars
- Alex DA13 rims (seems people don't have nice things to say about Alex rims?)

There's no serial number or any other stamping on the frame as far as I can tell.
Any ideas on what I just bought?
