My TT bike currently has a 56T front chainring which I essentially run in 1x mode (I have an inner ring but I never use it). This season I am replacing with a single narrow-wide 58T chainring and removing the front derailleur (although I may fit a chainguard).
My question seems simple but I’ve seen varying advice and usually related to 2x chainrings. Assuming the cassette at the back remains the same, by how many links do I need to increase chain length?
Thanks in advance
