Official G & J Clincher Rims Thread

[GiovanniLiCalsi]

I really need a pair of the cream colored Rubinas.
Anyone have a pair of them for sale?
I’m planning to have a set of Ghisallo clinchers made, with carbon fiber reinforcement.

Rubinas will fit wood without steel insert also.

Interesting.
I thought that they might, but those rims were designed to accept the double clinch type casing, and I wasn’t sure if the single clinch Rubena tire would lock in sufficiently.
Did you have to modify the rim by removing the inner locking ridges for the double clinch type tire?
That modification looks easy enough to do, but it would be nice to not have to alter the rim in order to fit the single clinch type Rubena tire casing.

Very nice bike, love it

and since you touched the topic:

Rubenas will also fit wood rims with steel inserts:

These rims on my 1906 WKC are the original ones - pretty sophistacted for a ladies machine of this age, since the inlays are actually made of alunimum !
The Rubenas did not need any alteration to be mounted on these rims.
The tires are actually the only not original part on the bike, even the chain still has the WKC-maker stamps on the links.... but enough of this- I don't want to spam this post more than I already did

no modification to the rim.....gentle heat and manipulation, and they locked right in....run it at lower end of psi, ......no problems yet.

This looks like someone has some colors available, maybe this is Classic Cycles on eBay??

My teens Pierce has this G&J type of clincher rim. It would be great if there was something beside the Vee Rubber tires that I've ordered from Australia. They seem to decay fast. Within a few months they started to show cracks on the sidewalls.

this is from a small bike shop in Leverkusen, and he only carries the red ones , the rest is out of stock unfortunately...

But one thing I know for sure: the quality of these tires is really quite good, with one piar I rode at least 1000 miles and the thread is still perfect.
So if you can cope with Red you might want to order a pair for your Pierce...

I talked to the owner of the German Bicycle Museum today and asked him about the White-Rubena-Issue and he told me the following:
The company is so tied up with their normal orders that they do not want to make more beaded tires at the moment.
One batch is about 3000 tires and apparently the antique bicycle collecting comunity is just too small (?) so they make modern tires which have huge demand right now.
So thank you very much for that Corona !
In Germany Bicycle sales went up by over 50%, everybody wants an new bike during lockdown, to stay healthy, travel to near by destinations etc. and bike stores are exempted from lockdown.

How about US-Bike sales ?

The situation is the same in the UK, and there is a shortage (and waiting list in some cases) of new bicycles.

Bicycle shops all over North America were cleaned out last spring. A friend had to go to 4 shops over a period of weeks in January to find a new beach cruiser type bike for his daughter. I tried to sell them not eh idea of a vintage beach cruiser from the 50s -60s but you know how 13 year olds can be.

1910 mead catalog.View attachment 1383934

Really interesting info but I have a question. I recently bought a 1920s Elgin that has an all metal rim similar to the ones in the '08 Racycle catalog but with a rolled back edge. I've found that a conventional 27 x 11/4" tire, kind of a standard 10sp tire circa '70-'80s is just a slight bit oversize but rideable. Any ideas on this? Thanks, Thursday
