Ishiwata 019

[h00k00]

Found this in a dumpster and now I'm trying to figure out what it is.

It is quite a mix. Shimano FC-M730 crankset, Campagnolo Euclid brake levers, Shimano front gear lever, SRAM grip-shift gear lever.

Cantilevers in the front, but not in the back, so the fork is probably not original. 28 inch wheels, but only back wheel with 40-622 tire was left.

Only decals are "Cr-Mo" in the top tube and Ishiwata 019 in the the seat tube. Any ideas when Ishiwata used this type of decal? Parts are late 80's, early 90's, but what about the frame?

It isn't an MTB it's a road frame with mtb forks, probably someones homebrewed old school lopro rig.
No rear brake bosses, very long chainstays for 26" wheels, Lightweight Ishiwata tubing for road use, weigh the frame is it 1.9 Kilo?? Then it's 019 Road tubes dude. Measure the spacing at the rear dropouts, road is something small like 12o 123456 fish.
Ishiwata did 025 tubes for mtb, they is rare, I got me some of these ones

That's what I was about to suggest, um, almost Expecting it to be 126mm or less...

I measured the space between rear dropout - 126 mm. But so it is in both my 1986 Nishiki Bushwhacker MTB and 1981 Formula Bici road bike. So that doesn't really help.

Although it has 28" wheels, the chainstays are shaped to accept bigger tires than road frames. Up to something like 44-622. There is similarities to Kuwahara Pacers - Ishiwata frame, MTB parts and 28" wheels.

I'll keep on looking for more information on the decal. 1977 is not the correct answer, since that was the year of the competition in San Cristobal. 1978 would be he earliest possible, but I don't think frames like this were made in late 70s.

What's on the driveside chainstay above the dropout?

Re:

1977 was more the era to start at, since it would only wear a win for a short while normally.

So you mean the chain rest nipple thing?

Lack of brake bosses on seat stays = Road surely

 

[legrandefromage]

whats it resting on by the BB? Brake bosses for a u-brake?
