Banging from drivetrain on singlespeeds/fixies...
What is the cause of regular and periodic banging from the drivetrain on singlespeeds and fixies? Is it the sound of a side plate on the chain being lifted up onto the teeth on the cogs and then slapping back down on the cog when the chain tension forces it back down? Sometimes the banging is regular on a particular bike. Other times, it occurs at particular moments. For instance, on my current setup, it happens sometimes on the first pedal stroke after I've been coasting for awhile, or when I take off from a standstill. The sound is clearly a "bang." Let me know. -FTU
