Ok so my SS MTB build is done and I took it for a test ride. Right off the bat something doesn't sound right and it looks like my chain jumps a little every so often. Took me a few seconds but the issue is that the SRAM link (I have a SRAM single speed chain and a Bontrager SS Crank with bashguard) is hitting the bashguard every time it come around. This SRAM link isn't the one like the 8 and 9 speed chains have it has both pins on one side and a plate on the other. So anyway this link is clearly wider than the rest of the chain and is hitting the bash guard in a bad way. Should I just ditch this link? This chain seems to have old school pins that could be reused (again unlike a 8/9 speed chain), is that correct? If so I think I will just take the link out and put in one of the extras. Also my chain line isn't perfect and is part of the problem here as well, I believe I have the BB shimmed so that it is centered but the chain wheel needs to come out more, is the proper fix a wider BB (I have the 113mm that the crank specifies in it's lit)? Or shimming of either the BB or the crank arm?

Thanks for any help.
