looks exactly same dimensions as kit chain - has very heavy grease on it - 50ft will easily get 10 of the 110 length chains, but I have a lot of 110 kit chains, so this will work well for stretch bikes that require just a bit more than the 110 length
no idea if it is stronger metal, but I doubt it could be worse : )
if I weren't too old to use it all up, I'd have bought them all
