Onza trials uni

Has anybody tried out the Onza trials uni form unicycle.com?
It says it has a splined hub, but it looks like a profile hub. Under the name of it, it says it has 140 mm cranks, but lower in the description, it says 125 mm. What does it come with? What are your experiences with it?

The hub is indeed splined, but it is not Profile; it is an Onza hub. It is similar to the Profiles, although not as expensive.

The cranks are 140mm, and have a rather large Q-factor, the pedals are a long way apart.

There are a lot of people riding them in the UK, as until recently it was the only way of getting a splined setup without importing one yourself. It seems to be a solid unicycle.
