I sent emails to each OEM that I could inquiring about pulley diameter(s). MS website had errors that prevented sending an email and Dinan website was down. Just guessing, I would say half of less of those I contacted will tell me their diameter(s), like it is some big trade secret or something. Hopefully, they will be reasonable and realize that savvy buyers want to know some objective facts about the products they are interested in. After all a pulley is a SYSTEM and their are so many details to getting a good design beyond just the single diameter that dictates performance. We'll see.

The community here would appreciate any additional efforts to complete this comparison.
