I have to replace the chain on the B'bird. I really should do the sprockets as well, but they're wearing pretty good. The current chain has a few tight links and causes that "graunching" sound but it's not stretched that much. So, I was thinking of maybe getting a cheap o-ring chain that would wear out around the same time as the sprockets do, then a year or so from now, replace the lot before I sell the bike. I'm on a bit of a budget at the moment due to extensive house rennos and a $25k bill for underpinning. So, just wondering if anyone here has recently bought a chain and if so, was it el cheapo, expensive and what did it cost?
