1986 Miyata 710

Miyata. A name once commanding indisputable respect within cycling. This Ferrari red, 1986 710 shows why the brand was the powerhouse it once was.

When bicycles come my way, on most occasions it is necessary to upgrade components because of various reasons (low quality, damaged, abused, etc.). So far, in my experience, Miyata has been the exception. Parts sourced when the frame was created are typically of excellent quality budgeting for functionality, style and longevity. Despite this bicycle coming to me as filthy, worn-out mess, the final product shows that the initial time and component investment by Miyata are some of the reasons why it looks as good today, as it did off the showroom floor.

Other than typical consumable items such as cables, tires, brakes and the like, this 710 is bone stock and proud of it. Tire replacement was necessary as the 30-year old originals were not even considered as part of the new build. All cables needed freshening up along with the brake hoods. However, finding period appropriate hoods for a set of Dia-Compe Gran Compe Aero levers was not quite so simple. I utilized all my known sources and eventually came to a pair of supple, black Dia-Compe hoods… That didn’t fit. A month later, the right size emerged as new old stock with a premium price to match. Begrudgingly purchased, the cockpit build could then continue.

Buying an off brand, such as Cane Creek, works to get a job done but a “good enough” attitude is a hard pill for me to swallow. Dia-Compe Aero hoods may be superannuated parts, lost with the passing of time, but they are still available and seeking them out is part of the excitement and satisfaction I get when finally putting down the wrench and saying, “now you are complete.”

Moving down the frame, all signs point to the budding importance of aerodynamics. This was part of the 1980’s major discoveries. How aerodynamics could gain advantages in the racing circuit.

Not only did the brake levers have an aero treatment but the tucked cables, also helped cheat the wind. Also, gorgeously shaped Suntour shifters were positioned on top of the down tube as opposed to on the sides. This was also in response to reducing wind resistance.

When using the shifters with the components intended, the marriage was harmonious. If one wanted cable stops instead, the conversion required creativity, to say the least. Rumor has it, Suntour made cable stops to fit the top mount boss but light research in finding them seems to come to hazy semi-dead ends. Other than bypassing the boss and using a clamp-on attachment, the other documented method is to locate flat back Shimano cable stops and modify the castings that protruded from the shifter base to receive the cable stops. A highly permanent but effective solution. Luckily, the shifters on this 710 polished up to an elegant luster and functioned flawlessly. No tricky cable stop conversion necessary for this steed!

Built and sold with a “triathlon design” this Miyata was a fantastic model for anyone who desired well-built, medium-end frame. With eyelets on both on the front and rear dropouts, commuters could attach fenders. And with triple-butted tubing mated with a strong component group set, even the weekend warrior could feel confident competing.

    Lovely. Obviously many hours of your time. Curious to know if you have any idea what the bicycle weighs in at?

      Thanks for the kind words, Mark!
      Before the Miyata and I parted ways, I failed to give it a proper weigh-in. However, the official 1986 Miyata catalog lists is at 23.5lbs. Being that I didn’t swap out many of the original components, I’m guessing that is not too far off from what the final figure would currently be.

    that beautiful red paint job does look like it just came off the showroom floor, I would be interested to see what it was like in the “as-found” condition, I am betting you spent a fair amount of time; cleaning, waxing and buffing that paint to the gorgeous shine it has now.

      You know, Ryan, I keep fairly meticulous records. I have a spreadsheet that shows how much I put into a bike in painstaking detail. How much it was purchased for, how much it was sold for and when. Itemized part lists with costs. How much profit made and how much, since I began this journey, I have spent since the beginning. It’s not that I’m that concerned with turning a profit (I often take a loss), rather, the numbers are just details to me. And maybe you couldn’t tell but I like the details. 😉

      I also always keep PDF’s of the ads from the bike purchases I make. I like to see what the previous seller said, months or years later, plus see what transformation I made to the bike.

      This purchase was made from Craigslist and when I got home, I realized I hadn’t saved the ad (which I usually do before I visit, just in case). Going back online, the seller had already taken the ad down. The previous shots lost forever.

      I was going to post seller photos of the bike but they are now long gone. What I do know is that the frame wasn’t in that bad of shape before I received it. It took a full tear down, cleaning, polishing, waxing and buffing but that is the treatment each bicycle receives. To what degree I take it is the question. Either way, I am sorry to say I have no previous pictures but I am, however, quite pleased with the results.

        Josh C, good for you man! What a splendid job you did restoring that bike. I stumbled upon this forum because I was seeking info about gearing ratios on all my old bikes to compare to my new one. What a surprise to see photos of a pristine machine. What memories! I have the same bike in my storage room. A ferrari red Myata 710 that I bought in March 1985 and rode for just over 1.9 billion kilometers. But I never ride it anymore – I keep it for reasons of sentimentality. What should I do with it?

        Thanks for the kind remarks!
        In regards to your fine Miyata, I fully understand keeping it around for sentimentality. But a light tune-up up which includes a oiling of the chain, some new cables/housing along with close look at the brake pads, and maybe a new set of tires, will cost you $100-$125. That small investment will yield a machine comparable to just about anything your local bike shop is selling these days for $1,500. Dust it off and stretch its legs! I bet those memories and old, familiar feel of a sturdy, well-built machine comes back to you in a powerful wave.

    Thanks for documenting your bike! I believe I’ve found a Japanese market model very similar to your 710. Info in this thread: http://www.bikeforums.net/classic-vintage/1074380-1986-miyata-team-2000-triathlon.html

      I am happy to see the post helped for identification, Billy.
      I do see some overlap between the Miyata Team 2000 Triathlon and the Miyata 710 but there seem to be subtle differences. For instance, I don’t see any front or rear eyelets on the Team and the semi-sloping crown on the 710 is a touch different. But, most of the bones used to build the bike are there including the Triple Butted steel tubing and scalloped seat stays, for example. As T-Mar from the C&V thread you linked mentions (T-Mar has a good reputation for being extremely knowledgeable in the C&V community, by the way), “this model is a cross between the 710 and 912. It has the 912 components but the 710 frame, as the 912 used the splined version of the triple butted tubing.”

      No matter how much crossover between the two models there is, I do hope you enjoy your Miyata, Billy. They are fine machines!

    This is my bike! My beloved red Myiata 710 – I rode it to work today. I am the original owner, have raced it, rode it, loved it, abused it, and it has always been my trusty steed! Over 30 years old, and still my only bike.

      There is nothing I love hearing more than a note from a long-time owner of a frame that’s seen it all from their saddle. The memories you have from your Miyata must be spectacular!
      In a time where the bicycle marketing industry isn’t just knocking, but busting the door down to get riders’ attention, it can be difficult to stay true to a vintage frame with all that “old technology”. But, for many reasons, many of us hold tight to our steel framed beauties. So long as you keep up your maintenance, I’m sure you’ll get another 30 years out of your 710 with no problem, Connie.

      Thank you again for the comment. Enjoy the ride!

    I have this bike also!! Bought at a thrift store for $40 about 15 years ago after the $400 bike I bought was taken off of my car. I like this bike way better! I haven’t ridden it much in years. It’s too nice to ever get rid of!

      Another gem still going strong! Wonderful find, Dana. Enjoy it!

    If I could only find one of these I would be a happy man

    Beautiful bike! I actually just got a seven ten myself on cl. And it also is missing brake hoods – which ones did you use?

    • Josh C.
      October 19, 2017

      Thanks for the compliment, Micah.
      Regarding the hoods, I keep every item I purchased documented but it doesn’t look like I put down the details for this one other than, “Dia-Compe aero brake hoods” with an astronomical cost of $31! With a price that high, I’m guessing I couldn’t find them anywhere and had to pick up a set on eBay. Sadly, that’s my best guess!
