Graceful Fat Shebas?
 

Any clydes ride them?

I'm totally stoked about Salsa's new Mukluk complete build: http://salsacycles.com/bikes/mukluk/

But a single walled, no eyelet, 32 spoke rim of that size makes me a little nervous....

With so much tire and low pressures, that rim's more than enough. It'll probably be pretty bouncy.

Where are the studs? I guess if you're guaranteed to have only snow, not ice, then that's fine. It would be nice to have a few studs though, just in case.

Looks like fun to me.
