:welcome: to the madness :wave: mate
I cannot help you identify the sprocket or wheeel but if you measure the holes spacing the diameter of the sprocket and count the tooth. I am sure any of the bike shop can help you get a replacement.

 

I googled information stamped on sprocket and mfg is ERGAL, probably 44 teeth (stock is 43), search from there.

 

Thank you , but its not that easy, i have been at all Bike shops arround here ...2 , and google ed the holes and Ergal , nothing. Maybe i have to start seaching in the UK or Germany , or replace the Sprocketholder.

 

Hi Folks,

After serval houers on the PC i found it ...

This rims are from Astralite and quiet rar made in the UK they only make 1500 rims a year and stop producing in 1990 . Now they start up again and this rims are for sale again.

They was made for racing only at this time and now they use them for cafe racer s .

And the sell sprockets too.

problem solved thx to google :wave:

 

FYI

Ergal is a trade name for 7075 aluminum.

Trade names

7075 has been sold under various trade names including Zicral, Ergal and Fortal Constructal.

Some 7000 series alloys sold under brand names for making moulds include Alumec 79, Alumec 89, Contal, Certal, Alumould, and Hokotol.



Glad you found some history on the rims!

 

Who woulda known - we have our very own Spock on VFRworld.
