i'm pretty much done building up my GTB now, the drive train is 3/32 and i ride brakeless, so i want to get the best 3/32 chain i can find. right now it has an SRAM singlespeed chain, does anyone have any recommendations for something really tough (and maybe quiet, too)?

For 3/32, I use a SRAM PC-48, which runs beautifully. The PC-1, because of the space is noisy on a 3/32. The PC-48, since it's built to be shifted and all that jazz can take a lot of abuse and wear.

I agree, the SRAM PC-48 is all you need.

KMC Z610HX (silver, bushingless); made specially for single-speed drivetrains. Businesscycles.com has it. It is rated stretch proof and is the toughest 3/32 chain.
Feels less springy than the PC-48 I had previously.

i think that greg goode recommends the KMC, thats the way i'm leaning. thanks for the tip on businesscycles.

I ran a PC-48 For a long time, sometimes brakeless. If your chainline and chain tension are decent, you will not have issues with a derailleur chain, in my experience.

Recently I upgraded to a PC-68 because it was pretty cheap.
