This is a 1985 Miyata Seven Ten in Sunrise Red with a Silver Steering Tube,  gold lug chasing and Black decals. It is a 21″ / 54 cm / Medium (center of bottom bracket to top of seat tube) triple butted lugged Cro-Mo steel frame with a Mangalight steel fork. The stand over height is 31″ directly in front of the saddle. 

There are 12 speeds available through the alloy Sugino GLP crank with 165mm crank arms with Look Clip In pedals and Campagnolo Chain Rings and the Shimano 6 gear freehub. 

The rear derailleur is a Suntour Accushift 2000 and the front is a Suntour Cyclone.  Shifting is through Downtube Mounted Suntour Shifters.

The rear wheel is an alloy Mavic CXP 33 rim laced to quick release Shimano Exage Sport alloy hub. The front wheel is a Mavic Reflex laced to a Shimano 105 quick release alloy hub. Both wheels have brand new 700x23c blackwall tires with Presta valves.

Braking is handled by alloy Dia Compe side pull calipers with Dia Compe drilled brake levers. 

The new black vinyl saddle is mounted to a black alloy Ride Tune seat post that moves freely in the seat tube.

Alloy handlebars are mounted to an alloy Sakae Ringyo stem.

There are eyelets for front and rear fenders, bottle cage bosses on the seat tube and a bottle cage mounted to the Downtube. The rear drop out has wheel locater screws. 

The bicycle rides, turns, stops and shifts through all of the gears and rings.

From the 1985 Miyata Catalog:

“Like all of our models, frame integrity is evident in the 710 and has been designed with the triathlon contestant in mind.  ChroMoly Triple butted tubing, fully lugged frame, Mangalight fork, Suntour gear system and Dia Compe brakes… A bicycle with the right frame of reference  whether you’re in competition or just street riding.” This is a sharp looking bicycle with nice components on an excellent steel frame with new tires, handlebar tape and saddle.
