Neither throwing a chain (to the outside) or dropping a chain (to the inside) is the same as chain suck. This is what chainsuck is: >The general reason is that the chain does not disengage from the bottom of the inner chainring; thus the chain gets pulled up< Normally, a chain link moves around the chainring and then disengages somewhere around 6 o'clock. But with chainsuck, the chainlink fails to disengage at 6 o'clock so the chainring carries the chain link from 6 o'clock to about 10 o'clock where the chain, chain stay and chain ring all jam up against each other. I have no idea what causes it, and the first time it happened to me was on a brand new Rivendell on it's maiden test ride. The bike was equipped with brand new components bought from and approved by Rivendell.
