I have no clue how many links are on any of my bikes because I don't need to.
I size the chain to fit the bike and toss the rest into the "extra pieces of chain that will probably not get used" pile.
Put it on the biggest ring & cog and make sure you have enough slack so the chain can ride over the teeth to the next ring/cog.



As far as chain stays the same length? That may be, but with some of the futuristic styling, where does the CS start?
Is the distance from the center of the rear axle to the center of the ring(s) the same?
