The Univega Specialissima is a clone of the Miyata 1000. Any relationship between the Gran Turismo and the 610?

What years were those bikes in the marketplace?

Anybody?

Does anybody has a 58cm Miyata 610? I have a Gran Turismo I can measure to see how they compare.

I used to have an 84 Miyata 610. Looking at the 84 Univega catalog, they look very similar, but I think the Univega might have a longer wheelbase. I don't think any of the Univega models were necessarily clones of Miyata models, just that Miyata made frames spec'd to what Univega wanted.

The geometry and materials used on the Univega Specialissima are identical to those on the Miyata 1000. There are a few branding differences but for everything else Miyata duplicated their model 1000.

Miyata 1000 Univega Specialissima compared

I'm just wondering if they did the same with their next tier bike.

Univegas were made by Miyata in the late 70s through the mid-90s. Miyata manufactured many different companies frames until the late 80s/early 90s. Panasonic brand is another example.

I know. But they didn't just clone their bikes. The only one I know they cloned was the Miyata 1000 and I wonder if they did the same with the Gran Turismo/610.

I haven’t checked every geometry parameter on the Miyata, Univega, and Panasonic but they are close enough to be the same frame. Any minor differences would be trivial. That holds for most of the Miyata/Univega line and, perhaps, Panasonic. Miyata built a lot of frames for other brands until the mid90s when they lost out to Giant in Taiwan. Giant builds a lot of frames for other manufacturers now.

The 1000/610 were the same frame with a different parts spec.

You would be surprised how minute changes can affect a frame, from geometry to the tubes being used to stiffen here and mellow there. While there were structural changes over the years my understanding is that for a given year, the 1000 and the 610 were different frames, in some years using different tubes.

on the other hand a univega specialissima and a Miyata 1000 of the same year are the same frame with cosmetic changes for branding.

No minute changes don’t really affect the frame all that much, especially not when it comes to long wheel based, relaxed geometry touring bikes. I would dare you to ride different frames blind (as in not knowing what manufacturer they are, not “blind” as in can’t see) and notice any real difference.

1986 trek 620 vs. 1986 trek 720. That year both frames had identical geometry but the 720 was built completely off lighter tubing while the 620 came with a heavier tubing rear triangle. The 620 has a stiffer butt, noticeable when you put a 200 pound rider with 60+ pounds of gear. Not so obvious on an empty bike.
