The biggest practical difference between the Z50 and Z51 is that the Z51 comes with a KMC "Missing Link" connecting link. The Z50 is meant to be broken and rejoined the old fashioned way using a chain tool to remove and reinsert a pin.
Very cool! I think I'm going to try the Z50 as I have the Parktool "chain breaker." And, it's $10 hahaha worth a shot... Thanks.
