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
If it's a freewheel problem that won't apply to fixed gears. Banging - how's the chain tension? How's the freewheel? Has it been through a winter? Getting a hollow sound when you freewheel it?
