I know how to size chains, but I want to know which length I should buy in the first place. I have notes for my other bikes having swapped tonnes of chains but not my MTB and couldn't find the email confirmation from the last chain order.
Sorry if I came across as being odd, just mentioned the lazy way (to me) of getting the right length with out counting links. As the counting links is difficult for me as I don't have the attention span.
I always do the "big big, add two" kinda thing when getting the actual length but in this case I don't have a chain to install yet and didn't want to buy a 128 link chain if I only needed 116 or whatever.
