My single speed came with a one piece chain and I decided I wanted a quick chain removal situation. Maybe I shouldn't have assumed, but I figured any 1/8" master link would work on my chain. The description of what I bought (ebay) is "KMC 1/2 x 1/8" Master Link for Single-Speed BMX Freestyle Fixie Bike Chains Z410".

After joining the chain withe the new master link there is way more play than I'm comfortable with. The plates on the master link are a bit less wide than those of the original chain. Is this to be expected? Did I buy the wrong link?

Thanks for any help..
