I have a 1 x 11 drivetrain setup on my mountain bike. This is stock from the factory, it wasn't a conversion. When I'm in the low gear climbing, there is a lot of chain/derailleur noise. It gets more noticeable when the drive is under more tension. Being in the low gear, the chain angle is fairly minimal, so I am really perplexed. The sound almost mimics when the chain rubs against a front derailleur when the chain is at a drastic angle rubbing against the side.
I'm afraid I am wearing out my drive train too quickly because something is not adjusted correctly. My old 2 x 10 was virtually silent.
Addition, when going downhill and pedaling, the chain was slipping teeth quite often.
Does anyone have any ideas?
After replacing the bottom bracket and spending the rest of the season fighting the noise, I have decided it's coming from the SRAM X style teeth on the front chain ring. When the drive train is squeaky clean the noise is minimal. However after a ride or two the noise starts to come back. It's only there when the drive train is under heavy load. It sounds awful, like my chain and teeth are grinding together. I can only assume it's the X teeth, anyone else confirm this on their 1 X 11?
