Wowowow, it's like a Raleigh Gran Sport. For being a touring bike you've kept it in beautiful condition!

Beautiful bike! What rear rack is that? It looks like polished stainless steel.

You will need 10 posts to be able to post your pictures so give it a day or two with some useful posts here and there to get up to that number.

As for the bottom bracket, as others have said in the thread you started elsewhere, the 68mm sounds about right for the shell but the spindle depends on the crankset used. Though I have never come across a 145mm spindle with the usual JIS standard. The exception being tandems.

Hello Jacco,

Thanks for the complement wish I could take some credit for building it. I just purchased the used frame and assembled it together from parts I purchased here and there. The rack is a Nitto Campee 32R, and yes it is stainless, did a few tours with a Blackburn rear rack and found they flex so much with a big load, made the bike almost to difficult to ride relaxed, the Nitto is much stiffer results in much less sway.

That is just beautiful. I love how you guided the shifters through the downtime. Great mod.

I think that the 1980 Gentsracer is one of the best-looking bikes Koga-Miyata ever built. I love that color and the classic chromed "socks".

BTW, I only just came across your post. If you're still looking for that crank, PM me. I think I have a spare set somewhere in my stash.

Hey all, new here, I have recently purchased a 77 Road Racer with looking to restore. Will post pictures once I get to my 10 post limit.
All parts look to be original bar the levers and wheels, love the mad SR Royal drilled out chain rings, already managed to source replacement 600 levers!

Has anyone had any luck trying to match the old style paints? It has such a subtle pearl finish to the paint that its hard to search/source. I assume going to a car painting specialist is my best bet and maybe mix with a transparent pearl paint.
Was going to deal the large chip by sanding back, treating with a rust converter, painting and then wet sand/waxing.
Chrome seems alright, just flaking on the inside of one of the forks, can anyone recommend how to prevent further chipping?

Sorry if this isn't the right place to ask the restoration question, the issues with resources online is they vary so much and I am extremely new to bike restoration and would assume that people have had similar experiences with their own Koga-Miyata's

Hi Koga-Miyata fans! Can anyone help me with the identification of this frameset? Thank you very much in advance!

Joined the Koga Miyata club this morning. I had seen a bike on Offer Up with no identification but it was clear a high end older MTB with carbon fiber tubes in aluminum or titanium lugs. It's a Skyrunner Carbolite from 1991 I think. The fork is quite unique, chromoly straight blades ( circular cross section ) in an aluminum crown that looks like it would normally receive suspension arms. I would say that it is not light at all contrary to what one would expect when carbon fiber is used. Looks like the bars and stem are steel and that is at odds with the high end components, mainly Deore. I guess the idea is that it be bomb proof.

I can't post photos because I had to leave it with a friend ( wife will kill me if I put another bike in the garage so I have to finish and sell some of my works in progress ). It's a striking looking bike and a real conversation starter. Never seen anything like it in the "flesh". It needs some work. The owner apparently didn't understand how quick release mechanisms work and the headset is very tight. Probably needs grips and brake pads swapped out. I guess I will ride it and see if it feels better than my '95 Specialized Rockhopper before deciding what is going to be sold.

That is a sharp looking set of wheels. I am just not that interested in anything more modern than this. I don't know if it is nostalgia for my own youth but I just can't get excited about over-engineered modern bikes where aesthetics, lines and proportion seem to have gone out the window.

Came into the possesion of a 1993 WorldTraveller yesterday. 66cm frame with Hardtlite FM-1 STB tubing and fork.

Thread started here.

Almost finished to restore my RidgeRunner to original condition. I could not find the original tires, otherwise it is like from the dealer in 90
Just when I thought I am done I broke one toe clip. In case you know what Shimano Deore XT toe clip goes with it, any help is appreciated.

JaccoW

Those are still one of the funkiest frame designs I've seen. How does it ride?

I ran across @John Nolan's Miyata Catalogs website in the Where are the Miyata catalogs now? thread. I think it would be fun to do cross-reference them in the future to see what overlap and differences there are between both Miyata and Koga-Miyata models.

Another thing is that I will probably be able to borrow a whole set of Koga-Miyata brochures from 1988 till 2010 including all the extras. Something the official Koga brochures are missing on their online website in most of that time period. My plan is to make some high-res scans and share them here, online on Onedrive and perhaps send them to Koga to update their list.

Thanks for the catalog links. I am not riding the bike much anymore. However, I am amazed how well it aged. I used to ride it in the Swiss mountains (20 years ago...). I was heavy, but awesome for downhill. I used to have an orginal rockshox (aftermarket) on it.

I've been looking for a nice vintage touring bike for a long time and this one made the wait quite rewarding. Went to pick it up by train and was thrilled to find that everything under the top tube was original and minty. A K-M Randonneur Extra from 1986 with (my guess) 2 to 3000 miles under its belt.





I plan to ride this baby long and far so will take my time getting everything just right. For now I put a boutique version of the Turbo saddle on it, Nitto seatpost and stem with a Nitto Ra(u)ndonneur bar plus Gran Compe levers. The original K-M R came with stem shifters so that was clearly something to rectify, I have a few sets of barcons lying around but chose to use an old 9 speed Dura Ace with worn indexing teeth: set to friction this thing, like a reversible cog, will live twice. Replaced the 6 speed UG casette with 6 + 1 HG cogs I put a file to, installed 32 mm Conti "Vivaldi" 4 seasons and put 3 coats of wax on the frame. As new! At some point I'll probably cold set the rear to 130 and go for 3x8 indexed, we'll see.

JaccoW

That's a really nice find CMAW. Looks brand new down to the rims and fenders even!

non-fixie 

Nice find, @CMAW! Love how it looks now.

JaccoW

I'm justs going to crosspost this here for other people who may have missed it: The Koga-Miyata 66cm Club - A Comprehensive Listing by @RiddleOfSteel.
He indexed all of the Koga-Miyata models that came in the extra large 66cm size and added names, groupsets, frame material and geometry notes for ease of viewing.

And while he may have only focused on the 66cm size, it still applies to the same frame in other sizes. Go and take a look.

RiddleOfSteel

Thank you!

I'll quickly note that 1) I put a link to the archived catalogs in the first post on that thread 2) that the vast majority of models were offered from the smallest sizes up to 63cm, from more basic models/trims to Professional level race bikes 3) that some years had the catalogs list only certain things definitively 4) that I focused on certain frame features, but not all frame/setup features because there's only so much space. Hopefully this inspires people to dig deeper!

RiddleOfSteel

@CMAW that is a gorgeous bike! A 1986 Randonneur-Extra would be my pick of K-M tourers as well due to their complete outfitting of braze-ons. A 1987 model would also be great as both years had them in super tall 66cm form.

JaccoW

I received a complete set of Koga-Miyata brochures from a Dutch Wereldfietser forum member including the technical additions. Guess who will be digitizing things soon?

JaccoW

It's quite a job to go through but here are the first ones:

• Koga-Miyata Brochure 1989 (German) - Compressed (5MB)
• Koga-Miyata Brochure 1989 (German) - Uncompressed (47MB)
• Koga-Miyata Specifications 1993 (14MB)

Enjoy

P.s. They are quite time-consuming to scan because they are close to an uncommon 24.5 x 33cm B4 size. Which is larger than the common A4 210 x 297 mm. Meaning I have to manually stitch every page together.
