Super Champion Arc en Ciel bicycle rim
This rim for tubular tires probably dates from the early 1970s. This was a solitary rim which I had found in a local bike shop. Although the rainbow decal looks a bit rough, this rim was unused and any scrapes are just from many years of shop wear during storage. A nice quality polished aluminum rim with a narrow width (20.5 mm.) and a shallow profile height (11.75 mm.). Metal ferrules fully enclose the spoke hole openings at the rear and I believe those are stainless steel grommets finishing the holes. Smooth braking track (no dimples on this model) and 36 spoke holes. 350 grams. This was a premium road racing rim but not the lightest Super Champion model. It might compare to a Mavic "Montlhery" (a bit lighter than the Standard model and heavier than the Pro or Extra Legere versions of that model).
Fiammi Red label tubular rims
Because of my local reputation as a sucker for odd old bike bits, I was tipped off that a local shop owner would just love to unload these old rims on me - Cheaply! How could I resist such an invitation?
These still have some spoke nipples stuck inside the deep eyelet sockets, embedded in ancient dried on tire cement. They should clean up nicely.
