91 sport chain question

[Tonto]

More sound silly but with all these new school parts out there I just want to make sure .
43 tooth fusion disc do I need a certain size chain ? I would imagine yes but what size or has n e one got one ?

If you buy a new one it'll need shortening anyway dude, always come with more than enough links 

[Tonto]

I was wondering more if there are different sizes in links like u do in headsets now mainly coz the chain rings are smaller these days

  Prob 1/2 x 1/8,most chains are this size -some are 1/2 x3/32 (narrower) but these are usually only found on racebikes.
