Hi got this from a buddy of mine for doing some bike work for him. What year is it and is infinity tubing any good?It has forged dropouts and best of all it fits me.I will post more pics when I get it built.thanks

hah i thought you were offering one for free

based on the decals and knowledge of the colors WSI used in the 80s, it looks like an 1989 Accordo. Infinity tubing is seamed, butted tubing. It's going to be heavier than other road bike tubing but still provides a nice ride (at least the bike i have made of infinity is a nice ride)

was it made in Japan or Taiwan?

It was made in taiwan and says designed in the U.S.A

with the braze ons for rack and fenders it could make a nice around town / grocery getter type bike

[edit nver mind i see it's just got one set of braze ons.. (i assume for fenders?)

Actually, this could be either a 1988 or a 1989. Inifinity, weightwise, is on par with Tange #2, so it is quite light. The one concession is that it is a seamed tubeset, so theoritically is not as strong as the seamless Tange #2, though I've never seen or heard of one that has falied at the seams. Seamed construction allows for much more economical manufacture. I'd appreciate the serial number for my database. TIA.

Well I will of course defer to the master but the decals are the same as my 1989 Ironman and both the decals and color are identical to my 89 Diamondback Apex. In 88 WSI had decals with lots of random shapes but in 89 they toned it down a bit

good to know about infinity tubing.. it's not well respected but i've never been disappointed with mine on my 86 diamondback apex

T-Mar do you, or did you, work in the industry? You are more knowledgeable than most everyone I have met.

1989 Accordo, with the decal font and graphics consistent with 1989. 1988, almost across the lineup, had lots of extra graphics, "squiggles," etc. 1988 models had squiggles on the seat stays, 1989 returned to "CENTURION" on the seat stays.

The Tange rep says almost all forks in 1989 were the same due to efficiencies in the process, so it could be a Tange 1 or even Prestige fork, simply because it was easier.

The only year I know of any black frames was 1989; that's only from what I've seen. Given the size of that frame, there is not much difference, weight-wise, between Infinity, Tange 2, Tange 1.

That will make a nice bike for someone. Smaller sizes, with white accents, seem to be popular with female riders as well, but going all black tends to sway them away. The pictures don't show it clearly, but if it's a later 1989, that could be an Avenir decal back near the saddle on the top tube. Avenir arranged the decal placement when their saddles went onto the bikes, and that continued into the Diamondback line for at least a couple of years.

Avinir was a brand name of WSI.. looks like they registered the name in April 1989.. https://www.trademarkia.com/avenir-73793851.html


definitely looks like the avenir logo on OPs frame

There's nothing unique about 1989. From day one, Tange #1 through #5 used the same same blades (i.e.made of the same material with the same thickness). In fact, if Infinity, 900 and 1000 weren't seamed, they'd be the same too. Options were things the profile required for the desired crown, rake and dropouts. You had to step up to Pro/Prestige to get something that was truly different. That's why all the all those early Ironman had red Tange decals on the forks, while they had the blue #1 decals on the seat tube, because Tange had one basic fork blade design used on #1 though #5 and they all used the red decal.

I agree. The Tange rep said the more aero blades on the Schwinn PDG Series Paramounts were Prestige.
