Hey, i need a chain for my new trials bike. what's a good strong chain that can be used for a 9 speed setup? I have my 9 speed ultegra cassett spaced out to 6 gears, and i need a chain that i won't have to worry about. i've had good luck with sram pc-59 chains in all my other aplications. but trials is a completly different thing. I've heard wipperman chains are good. but what model? I've also heard of using a bmx chain, but i'm not sure if it will work with a 9 speed set up. ANY IDEAS???
