Right, I seem to have read more threads and info than I can count on this subject, so looking for personal experience and advise.
1×9 set up with a raceface narrow/wide ring and a 12-36 cassette. Usual method would be to run the chain from big to big, through the chain guide, compress the suspension to get the longest chain length and then add 2 links. Then pass through the mech and rejoin.
This seemed to result in a chain the was too short and it promptly broke halfway up the first climb of the day.
I assume the best way to size up is either as above but with an extra couple of links in, or to thread through the mech and size it so that there’s a definite ‘S’ bend in the chain line as it passes through the mech?
Any other methods or anything (else) I should think about? Foolproof methods preferably 😛
