Araya rims machined inside the tire beads, why?
WHY would someone take a grinding wheel to Araya 700C rims from bead to bead (inside the tires).
Araya wheels still had original Miyata tires installed, on a Miyata 312 frame in otherwise perfect condition.
No good pictures even if I could post them. About 1-2" of grinding in between 2 eyelets seems demented.
Is this anti-theft disfigurement?

Is it just between the two spokes straight across from the valve hole? If so, that's where the rim was welded and ground to make for a consistent inside profile.

Wait; I thought your name was spelled "Camembert", even though it's pronounced "Cannenbere"......

Most likely the old rim tape deteriorated on the previous owner and sort of melted and stuck on to the rim. So the owner used a wire brush wheel to grind the material off.....

In a rare example of poor Japanese quality control, many OEM rims suffered a hasty "grinding" procedure at the weld.
And not just inside of the rim. I've seen OEM Araya rims with heavy grinding having created a monstrous variation of the rim's thickness across the brake tracks, giving the braking action a quite heavy pulsation that no amount of usage would ever smooth out.
Noting here that it was always the OEM rims from Weinmann and Araya that seemed to be the worst in this regard, while the aftermarket rims bought at retail tended to be of consistently higher quality. This is apparently what happens when OEM's drive too hard of a bargain on the price of a large order of rims!

SEE my photo retrieved by madpogue above, using flash was out of the question.
SEE the legend Earl Camembert on his bicycle - search YT for "One on the Town: Urban Transit"

As Floyd might say, "EARL!! What, are you crazy? You're gonna get yourself KILLED!"
Synchronicity - two nights ago, we found the near-doppelganger to that bike, an all-chrome '85 Ross Piranha. Judging by the cars, however, I'd say Earl's jaunt dates to about 1980. Gawd, that whole troupe were effing comic geniuses. "The woodchuck hibernates in snowy climes....."
