Chain for 84 tooth gears?

My team is using 84 tooth gears included in this kit
http://www.vexrobotics.com/products/accessories/motion/276-2169.html

we need chain for our gearing ratio, which chain should we buy?
A link would be ideal.

Your link refers to spur gears rather than sprockets. Spur gears can’t be fitted with chain, while sprockets can. In addition, I don’t think there are 84-tooth sprockets, so you will have to rethink your ratios if you need to use sprockets/chain. Here are the relevant links:

Thanks that was precisely what I needed

If you are still working on gear/chain ratios, take a look at this page, and scroll down to “Links”.
