Chain for 20/47?

Anyone know which chain I need for a 20/47 spocket combo? I'm running 19/47 with a worn 82 link chain.
Cheers
Colin

You'll need an 83 link chain, but I would recommend you fit an LTH Variochain top chain tensioner that pushes the chain down instead of up. I was running on the same combination of sprockets and when the chain stretched it touched the casing which ended up suffering chain rash. The Variochain tensioner sorted the problem.

I've ordered an 83 link chain, but re the pull down tensioner, how are the home spun ones performing, I seem to remember a few being made a while back. The LTH one is not a cheap solution.
