[QUOTE=NEXUS;8363076]tatfiend,

Another option if you upgrading a bike with vertical dropouts is to use the original rear dérailleur as the chain tensioner as I did with mine.QUOTE]

I was thinking of a chain tensioner or derailleur used as a tensioner when I wrote the post, just did not mention the derailleur used as a tensioner option.

I personally prefer to avoid using frames which require a chain tensioner of any kind for IGH installation as I do not care for the appearance.
