It's arrived at last the only one in the country (bar the other 20)

If you have chance could you take a photo of the cog/freewheel please?

How does it fit onto the hub. I would've assumed it would be like a standard freewheel but your closeup photomakes it look like there's a fixed gear style lockring?

I hope they haven't come up with a propriety hub to use their belt drive cogs.
Looks like a standard Hope Pro 2 hub to me.

Spaced the same way as a usual mountain bike SS conversion kit runs.
