I can't quite position my ENO hub exactly where I want it, which is in the bottom left quadrant so if the bolts come lose, the weight of my body will pull my chian tighter. Right now, it's nearly 90 degrees with a slight biased to the forward position. Adding another link makes the chian too long. Where can I get a half link for cheap? My LBS doesn't carry any (and I think they don't like SS'ers). I don't know how wide my chian is but it's the one that came stock on my Specialized Hardrock. Thanks in advance!
