Todd’s Unidentified Old 10-Speed

Posted

Today’s entry from Todd is of the neighbor’s garage-basement-barn variety, but it is unique in that it is a completely unidentified OTS.   Could be any of a few dozen marques, Japanese, and post 1974.   That Shimano Eagle rear derailer came out in 1974 according to Diraeli Gears. Oh, and I did run across these NOS Cherry Center-Pulls while researching this all out.

First off…love your website.
I was gifted this bike from a (neighbor) …it had been sitting (in
their basement) for quite some time. A long winter project ahead!
Here is what I can tell you so far:

Rear Derailleur – Shimano Eagle
Front Derailleur – Shimano 333
Handlebars – Sakae Custom Road Champion
Hubs – Shimano 333
Seat – Ariake 9 rivet
Brake levers – Dia-Compe
Brakes – Cherry, center pull
Stem – Jun SR
Cranks – Cottered

Original Purchase date – ? . It was purchased 2nd hand by the family I got it from in (circa) 1976.

I can not find a brand name. Head Badge is also missing.
Serial number: 27455 Z540575 (underside bottom bracket) The 27455 sits above the second set of numbers.
Hoping someone can ID the maker eventually.
Keep up the good work. Always look forward to the new submissions.
I will send you pictures after the restoration. Yes, she is keeping all the hardware…even those cottered cranks!

Thanks Todd

    Re. the Shimano Eagle rear derailleur, I had a bike equipped with one of these around 1971, so the source of the 1974 date is incorrect. This bike is what I call a UJBBTS. A Universal Japanese Bike Boom Ten Speed. Mine had a head badge reading, “Premium”. I bought mine from an LBS, but cheaper versions (Cadmium instead of Chrome plating, and lesser quality components) were sold by auto parts and department stores with various head badges. This is called “Badge Engineering” in motorcycle circles. Similar to what is extant today with UTFs (Universal Taiwanese Frames)

    Todd, I have this same bicycle, except mine has a headbadge.
    The headbadge is black “S” and white “S” intermixed, simpsons sears, MADE IN JAPAN.
    This logo was the Simpson Sears of Canada logo from 1964 to early 1970, when their logo changed.
    My serial number is 27455 Z569966. I have seen pictures of at least 2 others.
    None has any other markings or decals on the frame. Just headbadge and serial number.
    Before “Free Spirit”?

    I have tried to find out which Japanese manufacturer supplied the bikes, but no luck.

    this is “ROMET Tyler” made in Poland;)

    Appears to be a Simpson/Sears bicycle from the boom years. Japan made frame.

    Todd. The 27455 is a Sears number and the remainder is the bicycle serial number. The serial number is for a frame manufactured by Miyata of Japan. The “Z” at the start is for the year 1971. Who new that a Simpsons-Sears bike could be a Miyata?
