Difference between Nimbuses?

I´m looking for a new unicycle. Could someone tell what´s the difference between Nimbus and Nimbus II?

do you mean the frame, or the unicycle?

I mean the whole unicycle.

someone may correct me on this…

the Nimbus II has a (possibly lighter) wider frame, it aso has a better rim and different hub and newer model components.

Ok thanks

The Nimbus II is newer version of the Nimbus I think… According to a friend of mine, the Nimbus I was pretty much an Onza frame without plastic caps because its frame legs were super wide apart.
