Hi i'm in the process of building a fixie. I tried a PC 99 hollow pin SRAM chain, but it's making some noise. Is the chain the wrong size? Not sure what size it is. My rear cog is 3/32.

p.s. when pedaling, the chain tends to stick to the cog at places, as if it does'nt wan't to disengage, and kind of 'reluctantly' disingages at the last moment. Any thoughts?

Thanks...
