Re: large marge

That's a big rim.

Surly has some info about the rim in their catalog.
'Surly 2004 Catalog (PDF document)'
(http://www.surlybikes.com/files/Surly2004.pdf) 
Scroll down to page 12.

It's a 26" rim.  No 24" version.  Looks like they're outdoing even the
'Snow Cat rims' (http://www.allweathersports.com/winter/snowcats.html)
in the width department.  And they're double walled unlike the Snow
Cats.

Here is the text from the catalog:
