Thank you for the info!
Should I discover a leak, can it be JB welded?
Also am I on the right track staying away from the
Oring/Xring chains?
You can have that case fixed...I've had a couple done over the years. Just find a good welder...but like Sandblaster said...if it ain't leaking, I wouldn't make it a priority, unless you want to....other wise JB should band-aid it for a while
There are a few threads on here, with mixed answers/opinions about x-ring chains...but I myself won't run one.
Same with the 13T front, a few threads on them too...most of them suggest to not run one.
