A 1/8 chain will work with anything in any combination - period. A 3/32 will not work with 1/8 parts. Now, there are arguments that all advancements in chains are first seen on 3/32 because that is by far the largest market with the deepest pockets. Also, and because of market share 3/32 is available everywhere where 1/8 can be a hit or miss affair. Master links are not what one would consider a weak link but in the fixed gear world where losing your chain can be the difference in your status as a living, breathing human being a certain paranoia creeps in. I run 1/8 without a master link and instead of a normal chain break tool I use the ******** expensive Park plier type chain breaker. It save me from myself as it is the as close to automated removal/installation as you are going to get. If you are smart enough to fit the roller into the pocket the tool does the rest. No need to think about a thing or have the slightest skills. Love it to death but have your girlfriend/boyfriend/wife/husband get you one for a birthday present or something because they sure as hell aren't giving them away.
