Strange 27" Araya Alloy Rims
 
3 Attachment(s)
I have had these rims hanging in the basement for about 5 years and putting them on a bike that is going to local swap meet. Probably not too valuable, but a bit rare I would guess. Laced to early Shimano high flange hubs, solid axles front and back with Sugino wing nuts on the front hub. Came on a aluminum framed 1972 AMF Roadmaster Elite made by Bridgestone in Japan.
This link to 1960 and 1970 araya catalogs has the rim, but not in 27":

Anyone seen these rims before?

Yes, that is Araya's copy of a Weinmann model 256 from Belgium.

Here is an advert showing the versions for 20" wheel:

Thanks. Looks like they copied/borrowed the Model #210 from Weinmann. Dimples on a racing rim must cut the wind better!

doesn't "w/o hp" mean hookless?

Nice looking !

I have two, possibly three pairs of these in my shop right now. They're light and polish up nicely. Two came with high-flange Shimano hubs, all circa early 70s.

You are correct, they are quite light. They definitely would shine up brightly. I am installing them on a repainted early 70s Dawes Galaxy that will be sold at local swap meet so not going to take the time to polish them. They did true up easily. Are your rims quick release or solid axles?

It has been posted here at the forum that Scheeren made some of the Weinmann labeled rims. This statement came up in a discussion of Weinmann tubular models. Do not know if they did any of the wired-ons.

The subject rim is an Araya model 7B. The Japanese bicycle rim industry was based on standardized model designations, defined by the cross-section and material. Variables such as diameter, width and hole count did not alter the model number. Nor did the manufacturer. This design would be a model 7B whether it was manufactured by Araya, Kaga or Ukai, who were the big three of the Japanese bicycle rim industry during this era.

W/O HP stands for wired-on, high pressure. This means that there are designed only for use with tyre that incorporated a wire bead (as opposed to true clinchers or tubulars) and that they can accommodate high pressure tires. The term high pressure is relative and must be considered in terms of the era. Prior to the development of the narrow (i.e. 1-1/4") rim, most tyre operated with maximum pressures of 60 psi or less. Anything above 60 psi was considered high pressure during this era.

Thanks T-Mar Every time I restore/rebuild a bike I learn something new.

aren't rims labeled "w/o hp" usually hookless?

i don't know if they're always hookless, but all those i've owned labeled in this way were hookless.

they always gave me worry when mounting 1" paselas and inflating them to over 90 psi.

Quick release on all of the hubs, and I just realized I lied a bit. On close inspection, I've got two similar rims laced to high-flange Shimano hubs, but I see they're mismatched, one is Weinmann, one is Araya Light, both have the dimples, hence the confusion. Date code ZI on the hubs, same as another pair from the same haul.

I've got two regular Araya 27 x 1-1/4 w/o HP rims laced to a pair of older Hi-E hubs, but no raise at the nipples. Last pair I thought matched were actually Nisi. Go figure?
