Help dating this Miyata

Picked it up at a garage sale for $20. Miyata Sports Series, Has Thunder Bird deraileurs, which I have never heard of. thing weights a good 30 lbs, but is in great shape, just needs a good cleaning, no rust anywhere. Front and rear taillight along with generator are mint.

I always go with the Shimano date code when I can. Website www.vintage-trek.com has a full explanation of the process.

Dating tips for the Miyata:
- Know at least a few Japanese words and phrases
- take her to a decent restaurant
- treat her with respect
- don't expect anything to progress too quickly



Anyway, the Shimano date code is probably the best route to go. I'd guess early to mid 70's.

Thunderbird derailleurs were super common on lower end bikes in the seventies, I can't see your pics as I'm at work so I can't say any more than that.

Yea that should put it as a 73. Components can be tricky to use to determine the date sometimes because they can be replaced. but it looks like that old shimano stuff was probably stock. Looks like a lower-end high-ten bike boom bike but in really nice shape.

It's a cool looking bike but it's probably heavy as a tank, those thunderbird/eagle rear derailleurs with the bash cages are beasts! That miyata decal on the downtube looks pretty awesome, could you post a bigger picture of that and the headbadge?

Do the generator lights work? What are your plans for this, are you going to make any changes to it?

1973 Miyata MX-M. Shimano date codes probably won't be much help, as they did not consistently apply them prior to 1976. While the front derailleur is a Shimano Thunderbird, the rear derailleur is a Shimano Eagle. From the angle, I can't tell the version but I believe it's the Eagle SPO. The stem looks dangerously high, probably well above the instrertion mark.

You are so ahead of me. I was going to suggest classic pick-up lines.

The thread title just begs for it, no?

I have the sister bike, "Racer" model; Shimano 333 / Dura-ace. It's may commuter - rain bike = with hondo fenders. Excellent ride, I wouldn't sell for $300-400.
