Did a search, but didn't come up with anything. I might just not be searching the right terms. Surely someone has asked this before.

Anyway, what's the difference other than the lack of the nice look of lugs. Ride quality differences, weight, etc?

Looking at Diamond Back Expert (I think. I'll find out for sure if they answer my email) as an upgrade to my current daily beater and it's tig welded. Current bike is Tange Champion #2 lugged.
