Help with rim specs
 

I've got a 1991 PDG Series-5 with the original Wolber Alpine hard anodized rims.

Unfortunately that's the only information I can find about the rims since the labels are long since worn off and I don't know a model number for them.

Does anyone know the ERD for these rims?
I've found the ERD for the Wolber Super Champion Alpine T430, but I'm not sure if that's the same rim.

Measuring ERD isn't especially difficult - easier if it's not laced though. :o

Sutherlands (from after the date they started manufacturing the style of rims you have) has the info you'll need. Find the section for 700c rims, look up Wolber rims, find the general rule, and then see if the model you have is an exception. I suspect that they will be the same ERD as the ones you found listed - and I'd take this to be the case unless there are exceptions for Wolber rims with "Alpine" in the name.

Thanx!

Spocalc lists the Wolber/Superchampion T430 Alpine as having an ERD of 622 for the 27inch wheel
and 614 for the 700c wheel.
