Roval wheel identification

[LoCo Guy]

I acquired an old Cannondale aluminum frame with nothing but a derailer, chain, crank, and two wheels on it. I really know nothing about the sport or equipment, but I googled Roval wheels and was impressed with the prices on them. I am trying to identify the model wheels that I have. They are aluminum, and tubular.... not totally round tube, but hollow nonetheless. The width of the wheel where the tube would lay is 20mm wide. The diameter of the wheel is about 640mm, plus or minus due to the measuring tape bending over the quick release. Some pictures are uploaded.
I'd appreciate help identifying what I have here... Thanks.

Looks like the bike could be a Cannondale R600 from back in 1996 or earlier.

They had the seat stays funny design to tighten the rear triangle compared to my 1997.

You see the seat bars come down from the saddle to a point in front of the rear axle?

The design after that, Cannondale returned to the design of intersecting the seat stays at the rear axle.

There is a website called bikepedia that is like a library history site for many bikes. Sadly the 1996 Cannondales don't have images.

This is what I mean by the seatstays hitting different areas of the chainstays.

As far as the rims being tubular, I don't think so. They look like regular style CLINHCER rims that require tubes.

Tubular rims are those that get the tires glued into place.

These just look like they are missing the rim strip inside that covers the spoke holes. Also, the rim looks bent at the section that is at the top of the fork. Or could just be my view on the screen but looks damaged.

Beanz, thanks, but these are the type that the tires are glued on. The rear wheel has the tire still on it and it is definitely glued on. The outermost surface on each wheel is basically a smooth but slightly concave trough. I'm sorry I did not take better pictures... I was mainly focusing on the bike frame at that time. I do not see a bend in the picture or on the wheel itself. There is one missing spoke. I ran several searches for Roval wheels with a diameter of 640mm, and a rim width of 20mm but did not see any with those specs.

Ah ok! I think the owner did quite a few mods. Looks pretty different than a stock Cannondale of that time I think. With the different cable housing also. I knew a guy who put metal housing on his bike. That's what it looks like in the pics.
