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.
This trick I do as I find counting links annoying https://www.sheldonbrown.com/derailer-adjustment.html#chain
On that link is an image that I can't seem to get to inbed here. Explanation in the text as I wished to quote but cannot on a phone.
