Chain Length for FS ? need advice
Does anyone know if I need to add links to the standard chain length for a 4 inch rear travel FS bike.
The frame is a Santa Cruz superlight and it will have a 9 speed transmission, I am wondering if the additional travel requires more chain length than standard 9 speed chain length ?
Thanks !

No, you might actually have to shorten the chain.
I had to take an additional link out of my chain. When I checked the length in the stand, it was fine, but then when I sat on the bike, the chain was too long with the suspension loaded.
What I always do, is put the chain in the big chainring and the biggest cog. This will provide the worst case scenario. I make sure the derailleur isn't overly stressed in this gear. This is also my "insurance". If the chain is too short, it could rip the rear derailleur off the bike. Granted, you should never be in this gear when riding, but there may be the freak moment. So, I make sure there is plenty of chain length in the big-big gear.
Then I switch over to the granny gear and small cog and see if the chain drags on the bottom jockey pulley of the rear derailleur. Chances are it will not, so you're good. If it does, then the likelyhood of riding in that gear "should" be none, so it's not a big deal.
Better to have the chain too long, than too short.
