Sure looks swaged to me. The one I had was crank arm+spider a single casting. Later model?

Hey, it's free, give it some riding time. You might like it. At the very least you have a rack and what looks like some shimano golden arrow parts.

I learned something today. I had always thought these were cast as single pieces, and that the "swaging" was referring to the spiders which had chainrings irremovably attached.

I'm giving it away to a friend's brother, rack and all. hope it gets used.

Ross Professional Gran Tour 10-Speed Bike

I was a little confused about what you guys were referring to about the swaging, since the picture in post 26 sure looked like a regular single piece casting followed by machining with nothing in that picture showing anything swaged. Then I looked back at the other pictures showing the crank on the Ross and finally saw that the spider and crank arm were two pieces. Okay now I understand, on that design the spider was swaged onto the crank arm.

If those pieces were steel, no big deal. I had an old Suzuki with a roller bearing crank, pressed together, that model of bike was commonly used by the drag racers. 100 hp at 10,000 rpm and the cranks held up (usually �� ). Aluminum though? Seems like a poor spot for that fabrication method.

Anyhow, looks like a nice free bike.

With my penchant for low-mid-range touring bike based commuters, I would be all over that, especially for $75, if I didn't already have one. Mine came with very a nice Rigida 1320/700C wheelset, that I repurposed for my 76 Raleigh GS, and replaced with a self-built custom Van Schotthorst Saphir stainless wheelset with Uniglide 6-speed freehub.
