I presume you own it, based upon the verbiage under your avatar. As you may know, the market in many areas ain't what it used to be.

What it has going for it is Miyata, a great brand. Splined, triple-butted frame is awesome, I own one and can attest. The Shimano 600 was the "Ultegra" of the day and is very nice. Everything is in great condition, down to the rims, not showing too much wear there.

I have no idea what the bike market is like in NW Ohio, but in my opinion if you are wanting to maximize your sell price you probably aren't going to do it on your local Craigslist. Would you consider listing it on eBay? If you do, you might consult WRK101, AKA "Thrifty Bill" who can give you pointers. He has good things to contribute and knows the ups and downs of "the bay".

To me it is a very desirable bike. I wish you luck!

It looks great and, should be easy to sell. But, it's a "buyers market" right now for vintage bikes. There's too many old bikes & not enough people interested in buying them. Everybody is looking for a bargain. So, don't price it too high.

Look at the Ebay & Craigslist finds in the regular classic and vintage sections. There was a 1987 Miyata 912 posted this morning in CA, I think for $400 asking, also in great shape. If you have the room, it might do you well to hold onto it, rather than list. If it's larger than a 58cm, your market becomes very limited. Today, you could probably list it for $400, and expect to sell just north of $300 locally. eBay is it's own thing. The market will be saturated in a month or so to be ready when people start looking.

In my market, $300-ish if it is ready to ride.

Really depends on location. Short of having Dura Ace parts or better, I do not see any DT shifter bikes here going for $300. It should for sure, but the market for DT shifter bikes has gotten really soft. Buyers just don't want them.

Is the rear hub Uniglide? Only a sophisticated buyer would care.

1986 Miyata 912 used a 6 speed freewheel.

Pretty sure it used a Uniglide 6-speed cassette, not a freewheel.

The 1986 Miyata catalog says “New Shimano 600EX 13-24 teeth sealed”. My ‘79 912 and subsequent years came with the first versions of Shimano freehub and Uniglide (UG) cassette, known as 600EX. Velobase shows a 600EX freewheel, but all 600EX rear hubs have freehubs, hence cassettes.

Scroll down to "Hubs" on that page, and you'll see a 600EX freewheel hub. I have one, bought new BITD. Probably not applicable to this bike, however.

I own this model for this year. I removed a freewheel from the rear wheel, not a uniglide cassette. As madpogue pointed out, there are sealed freewheels and QR hubs that accept either a cassette or a freewheel. Since the rims are the brown UKAI hard anodized, I believe that the equipment is original to the bike. It'll still use a different splined shimano tool than the current HG lockring tool. UG only needs two chain whips.

Guess the takeaway from the above is that a Miyata 912 could have as original equipment either a 600EX freewheel or 600EX UG cassette. The observation on a given rear wheel, short of disassembly, would be to look at the center of the cluster while backpedaling the crank. If it stays fixed (relative to the hub) when the cogs are turning, it’s freewheel. If it rotates with the cogs, it’s a cassette.

Apologies about missing the 600EX freewheel hub in the Velobase link. There it is. Oops.

Looking back historically, it’s interesting that Shimano didn’t make more of a big deal about the advantages of cassette rear hubs with their inherently wider bearing spacing and stronger axles when 600EX was introduced. I’ve got Richard Jow’s original 600EX group review from Bicycling Magazine, October, 1978, where he mentions that feature in a photo caption, but more text is devoted to the wider flange spacing for lower spoke tension difference between DS and NDS. But cassette hubs certainly opened the door to wider hubs and more rear cogs without axle failure concerns, not to mention the ease of removing/changing a gear cluster that hasn’t been heavily torqued onto the hub.
