I was cinching the chains pretty tightly to minimize chainstay taps. Went to put on a 2.1 and I found the sidecasing was being worn through on the weirwolf. Though not as much, there was some wear on the saguro as well. I cut all the chains off and am going to try shorter chains, longer zip ties, and keeping the outside chain loop parallel with the sidecasing. Also will not cinch them so tightly. Obviously, more testing needs to be done for a long term setup.
