Sturmey Archer 8 Speed Hub - What Chain?

[cosmicbike]

My latest acquisition is an Optima Lynx recumbent, and has had a Sturmey Archer 8 speed hub gear fitted. In it's original form it would have been 9 speed.
I've looked at the SA website, and concluded the sprocket is 3/32", which would suggest I need a 3/32" chain.
I guess the question is whether running the current 9 speed chain is OK?

9 speed chain is nominally slightly thinner so I suspect it'll work but I wouldn't be surprised if it farks up. Chains are usually the cheapest part of the drivetrain (maybe not at recumbent lengths, though) so do you really need to risk it?

10 speed chain works on an 8 speed cassette, so I suspect 9 speed chain will be fine on your hub.
