Vintage Bicycles Done Proper :: Portland, Oregon
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.
