I figure that basically any steel chain equal to or larger than #25 will withstand anything I can make the robot do to it. And then I make my selection based on which pitch size has the most convienant sprocket sizes and bores, etc.

And based on what parts we already have and don't need to buy: i.e. sprockets from last years robots will be in this year's robots. maybe some chain (with lots of new lubericant), definatly some big sprockets that never got used lat year. that kinda thing.

edit: our chain and sprockets are from McMaster Carr. Sprockets are carbon steel, chain is steel of some sort.

Never brok one, but we did slip them off sprockets. But that was our fault for a poorly designed drive train.
