I'm new to cycling but a lifelong athlete so the only other road bike I owned was a 85 Peugeot 531 Reynolds it was slightly too big for me but I just love to ride I sold that to upgrade and this is my upgrade. It was originally listed for $260 I offered $160 and he bit. Mind you I know nothing of Miata until after I bought the bike. After finding out what it exactly was I was surprised that I even got it at such a low number. But everything glitter isn't gold and the bike has some things that I would like my fellow bike forum members to help and point me in the right direction!

So after doing my research I found out that I don't have Shimano 600 components I know right son of a gun!

1.Shimano 105 front derailleur dura ace crank arm. (This is normal correct?) *Can someone explain why some 916 got 600 and others 105 dura ace??PLZ
2.dura ace rear Derailleur
3.dura ace hubs matrix iso c 11
4.dura ace index
Now the mystery lol
5.Rx 100 shifters?
6.rx 100 brakes?
7.icon stem!?! I know thats aint stock!
8. Centrion handlebars?
So im thinkng they switched out the braking on me??
I cant post pics yet untill after i.post 10 times

Here's a link to the catalogs, the 916 model is from the 90's, you should be able to find the components in there.

The simple answer is allot can happen in 30 years, once you have some more posts you can put up pictures and then forum can really help. A You ,mentioned you need to get to 10, I think you can do 5 posts a day, comment on others posts etc.

Based on the components your listing the bike seems well appointed and Miyata made good stuff bitd. The big question..does it fit?

So is dura ace better than 600? Is 105 the same as dura ace?

The wheels move freely im just confused about this grey lubricant like substance near my Hubs??

Briefly, 600 eventually became the Ultegra group, and, generally, RX100 < 105 < Ultegra < Dura Ace. However, all of these groupsets have evolved over the years, and the differences between these groups today are far less than what they used to be. I haven’t perused the catalog, but it sounds almost certain that some parts have been swapped over the years, and that’s not uncommon. Parts used to be more compatible with each other, so brake calipers could have been swapped out independent of everything else — no big deal. Sounds like those are all good parts, even if they don’t necessarily match.

You posted pics just as I was replying. Looks like a nice bike with good parts. A couple of observations — if the seat post is where it fits you, this bike may be too big. Also, the closeup of the brake caliper shows that the quick release is open. The narrow part should be rotated so that it points down.

All things considered, smoking deal for under $200.

You are correct my seat post needs to be raised! In terms of the quick release on the brakes i thought that lever was to make my brakes more or less responsive? Either way i know i got research to do! Thanks for the response this bike is by far the best Ive owned or ridden.

yeah, man....that's a beauty! congrats!

No! Adjust your brakes to the correct tension when the lever is down (closed). Opening the lever (rotating upward) allows you to remove the wheel when needed without deflating the tire. Ask lots of questions, we’re a helpful bunch.

Thanks for all the info I appreciate it!

You asked about the hub grease; I suspect it’s excess grease from a recent hub overhaul, just wipe the excess off, and you’re good to go!

dreamcatcher88

Thank you and you're right i have the dura ace hubs on them

dreamcatcher88

Man I'm a Noob in every sense of the word but I do have the athletic ability I don't know how I f*** around and looked up on this 916 Dura-Ace crank dura ace rear derailleur dura ace cassette Dura Ace index shifters and now I just found out this mother f***** gotten Dura-Ace hubs I'll be damned the rear is 8 integrated so basically what I'm asking is on the 8th integrated can I put a 10 speed cassette and of course I would have to change the rear derailleur front the weather and so forth I would do my research but am I on track here? 7400 series Dura Ace hub. Whoever owned this by previously I was planning on doing something serious and I appreciate their taste however the f****** RX100 brakes have just got me throwed off man

just found out that my icon still has got a recall from Trek and we just so happen to have a brand new Trek shop so I will be taking it back and see if they replace it I've already confirmed that it is the model that was recalled so we'll see what they have to say about a black poor homeless cyclist looking for a recall interesting

There is nothing wrong with RX100 brake calipers. They certainly don’t justify obscene remarks!

They are what is considered “medium reach”, while the Dura Ace, 600/Ultegra and 105 series only had short reach (at the time). So if you need the greater reach (defined by the frame), they work just fine. Yes, DA calipers, which I have on one bike, feel wonderful and have ball bearing pivots. But I also have RX100 on the other bike because it needs the greater reach and it works just as well. BTW, there’s a later series of medium reach Shimano calipers known as BR600, which are basically RX100 with ever-so-slightly nicer finish.

The best way to maximize brake performance is to use Kool Stop salmon pads on any of these calipers.

That Icon stem is pretty far from beautiful, IMHO. So you’d be making an esthetic improvement with any of the good looking forged quill stems out there, new or used.

And good luck with that DA 8-speed rear setup. It is not compatible with any other Shimano derailleurs or shifters.

I’ve got a Miyata CT3000, it’s maybe 3rd or 4th from the top of the line. It has a carbon wrapped aluminum main triangle with Al fork and triangle. It is light and responsive and came with a full RX group.

Miyata is a Japanese company and in the 80’s the dollar was very strong. Japanese bikes and components are made extremely well and could be sold at prices that undercut the European competition.

As the 80’s drew to a close the dollar lost more and more purchasing power in Japan, so to keep their product competitive Miyata sent over extremely nice frames with more budget conscious components. The mid 80’s 912 with Shimmy 600 components became the 914 with 105(?) and the 916 with RX.

Thing is they work just as well, more expensive means lighter weight, and sometime durability was sacrificed to cut the grams. You have a sweet ride with solid components.

That stem is a safety recall it sounds like? Shouldn’t have a problem swapping it out. No company wants the reputation of its products causing injury.
