I agree except for the recumbent trike I ride on bad arthritis days which takes three 2 wheel chains to operate. I had a Pedro and now a Park and they are much messier than my 2 wheel chains which I clean in an industrial ultrasonic cleaner but the Park does a decent job as did the Pedro I tried. When the Park wears out I will go back with a Pedro as I think the Park slobbers more fluid/filth on my stand than the Pedro did
