Got around to swapping a matching 5th Icon Vector 5 onto LX570 w 285/75 R17 KO2. Issue is the chain carrier in spare tire location is just a hair too large to fit thru small bore on Vector 5. Any elegant fixes others have come up with, ideally reversible? Is it a pita to thread the chain back into the crank housing if I put in a screw close (locking) caribener on frame mounted side of the crank? Would detach chain from caribener, let run out free to spare tire side of crank. Any ideas appreciated
