Thanks for posting, Gary. That interesting article confirms my strong aversion to today's ubiquitous "microdrive." No 20T granny rings for me! [Now that I understand chain suck (thank you, Gary!), I also realize that my "obsolete," much-maligned, chainstay-mounted U-brake at least provides protection against it.]
By the way, if chain suck specifically refers to the failure of the chainring to disengage from the slack (bottom) chainline, what do we call chain entanglement caused by a freewheel seizing up and creating slack on the drive (top) chainline?
