Also the case that you can aovid a lot of ther mess and maintenance
of a chain drive, at least with hub of single speed gears, by just
enclosing it, which does add a little weight but doesn't compromise
the efficiency (and by reducing the amount of chain wear from road
clag may actually improve matters over the longer term).
As an aside SWMBOS Nissan has chain drive camshafts, service instructions?
None. No service required.
Having suffered a cam belt failure that sounds good to me!
(yes, I do appreciate chains *can* break).
