Tech What chain?

[zenbiker]

My commuter is a single speed conversion using what ever front ring I can find in my box of spare parts... Probably a 9 or 10 speed. Rear cog is from the single gear kit.
What chain should I use? I've been using the cheapest 6,7 or 8 speed I can find...

If your chain stays on and rotates smoothly stick with that. Cheap is good, reusing is better.
