Can't quite work it out from the pics on t'interweb, but I've just ordered some wheels with the singlespeed / trials Pro II hub on the rear, and am wondering how the cogs / sprockets etc fit on?
It looks to me like they come with a series of spacers and they have underneath them a squashed up version of a Shimano freehub, so the cog has to have the appropriate notches out of it to fit. The spacers are used to get the chainline right, but is there a lock ring similar to a Shimano cassette to keep it all in place?
Like I say - probably a silly question, but can't quite get my head around it.
cheers in advance.
