Heads up. I have an 15 year old C/D tagged Enosoluzioni OMAC. Looks exactly like the current 220 model, but maybe not. These replacement rollers fit....well sort of. I had to trim the nylon bits to fit between the pillow blocks 1/8 inch. Saw 1-1/2 inch off the passive steel roller rod so chain ring would clear. Drill indents for the set screws into both steel rods. In all it took about 3 hours of fussing around... but it works! Cheers!
