Wouldn't the cinch system pull the left side in as far as it will go?
I'll be honest. I had mine apart 4 or 5 times when installing it. Second guessing the number of shell spacers on drive side. Even though instructions said 73mm she'll needs one on DS and zero on NDS. It just kept looking a bit wrong. In the end I just followed instructions and then left it.
The cinch is how your chainring installs.
The "system" you talk of is just the 61 full grown Issac Newtons you need to install that bolt. I had to add an extension to my 8mm hex, and I still don't know I got there. Then you look at the thing and think 'fuck - maybe it's not close enough to the bb shell...'.
So I agree with Dales. If it doesn't push from side to side like MattyP suggests. And it spins ok... Leave gud enuf alone.
