My first chain cleaner was a clone of the Barbieri and worked ok but
the Park is a lot nicer. Barbiere nominally has that wire loop on
back to retain it in place by hooking over the bottom of the RD
cage, but requires the bike to be suspended so the chain can be
moved in the forward direction. If you can't suspend the bike,
the chain must be run in reverse, and the Barbieri has to be
hand held in place. The Park recognizes this and gives you a
handle to hold the cleaner with. I think the brushes on the
Park are a little more aggressive in cleaning and seem to have
lasted a lot longer than the Barbieri clone I started with, the
Barbieri brushes looked motheaten after a few years. Park
also holds more cleaner - I prefer straight citrus for its aggressive
degreasing action. Yeah there is a big cost diff but in my book it
is worth it.
