I used a Bell chain on my 3/32" fixed gear for a little while. Thinking that the gold quick link would be the weak link, I took it off. Well, when I took the bike out for a little test, the chain snapped during a skid. Afterwards I discovered that the outer plate of the chain is NOT meant to be rejoined--the mushroomed end of the link severely weakens the outer link when it is being pushed in and out. Moral of the story: Do not try to rejoin the chain with a regular link (or add new links once it's been shortened) and only use the connector link for rejoining the chain.
