I'm still running my full length chain on a converted 3x9 to a 1x9. I'd like to shorten the chain, but I'm not sure how many links I should take out. I'm running Sram X9 rear derailleur if it makes a difference.

TIA

Do the same as the 'big-big+2' method - except the front ring will be the only ring to choose from.
Clarity:
- Wrap chain around front ring and largest rear cog (bypassing the derailleur)and add 2 links (1") to the closest complete link.
Chop off excess :thumbsup:

Assuming the chain was the correct length on the original setup, subtract as many half links as the difference in teeth between the now chain ring and your largest of the triple set.

Otherwise, do as Highdelll suggests except that that would give you the shortest possible length.

Regardless of which method you use, you'll get the shortest possible chain length. If you don't change the RD you might prefer to leave a few extra links in so that if a link gets damaged, or the chain breaks, you can simply cut and splice, without needin g to add links.

Hi again, I have a spare KMC X9SL (Hollow Pin) chain. Is it possible to remove links from this type of chain? I checked their website but did not see any info on removing links.

Thanks,,, BM

Not sure about that particular chain, but usually hollow pin chains have a series of solid pin links at one end so they can be shortened.

Check both ends of your chain. If there aren't any solid links you can still cut it, but will have to be super careful pushing hollow pins out. Obviously you cannot re-splice it except with a connecting link.

resplice w/ a normal shimano pin then use a trusty DeWalt ( fcuk Makita or Ryobi) screwgun w/ a 1/16" bit to hollow out the bit.
Remember to hold the link steady w/ some slip-joint pliers! :thumbsup:
