Wipperman no good or just over priced??
Just asking-using a SS wipperman 9 speed-seems ok-3000 miles very infrequent lubing-and never cleaned-other than hosing grass and grit off when needed.
I don't like much lube on chains or cogs-turns to black crap that stains everything it touches
so I rarely lube it-and then just with whatever spray lube I have at hand-every few months maybe
