This is a 1984 Miyata 912 in  Metallic Black and Silver Head tube with Silver decals. It is a 21.5″ / 54cm / Medium (center of bottom bracket to top of seat tube) Double Butted Cro-Mo lugged Steel frame with a Cro-Mo steel fork. The stand over height is 31″ directly in front of the saddle. 

There are 18 speeds available through the Shimano Deore three ring (52 Sugino / Sugino 42 / Shimano 28t) alloy chainset with 170mm alloy crank arms and the Shimano 600 Ultra Glide 6 gear (13-24t) freewheel. The pedals are alloy MKS Esquartz 102 with steel toe cages and black Miyata leather straps.

The rear derailleur is a Shimano 600EX and the front is also a Shimano 600EX . Shifting is through Shimano Downtube mounted Friction Shifters.


Both wheels are Araya alloy rims drilled for Presta valves laced to quick release Shimano 600 alloy hubs. Both wheels have brand new 700x23c black wall tires. There are Shimano dropouts with wheel locators.

Braking is handled by Shimano 600 front and rear Side pull calipers. The brake levers are alloy Shimano 600 levers with tan hoods.

The black vinyl Avocet saddle is mounted to an alloy seat post that moves freely in the seat tube. 

SR alloy handlebars are mounted to a SR Royal alloy stem. The stem is not frozen in the steering tube.

There is a bottle cage on the down tube. There are eyelets for front and rear fenders. 

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

This was the top of the Semi Pro Line and number 4 in the entire Miyata line up. At a claimed 24lbs, the 912 weighs only 2lbs more than the top of the line Team Miyata SL. 

For less than the price of a generic Bike Shaped Object that anyone might buy online or from a store that sells bicycles in the Toy Department, you could be riding this vintage bicycle with quality components. The fact that it is still rolling down the road is a testament to how well it was built.
