I've built my bike with a Rival 1 drivetrain a while ago. Other than the brake calipers, it's a full Rival 1 kit with the XG-1150 cassette. Right when I installed it I noticed that it runs a bit more loud and rough than I would like. On the first ride I also noticed that on the 12T and 10T when I pedal it feels super über rough. I rode it for a while, and then i've read tales on the interwebz that even on 11spd drivetrains, Eagle chains work a bit better and smooth things out. I got a GX Eagle chain, which i've been running since. It's true, the roughness in the 12T and 10T is gone. But still, the drivetrain is loud in every single gear.
If the drivetrain is clean, it's almost okay, and if I ride mostly pavement it stays that way for a short while. But when it sees dirt... Oh my god. I clean everything meticoulusly (Park Tool chain scrubber, degreaser, soapy water, compressed air etc.), go for an offroad ride, and after about 2-3 hours on dirt it sounds like I haven't cleaned or oiled my drivetrain in decades. It's so bad, it drives me insane.
At this point i've tried like 8 different lubes ranging from wet lubes to PTFE dry lubes to Squirt wax. Nothing worked. I know how to set up an RD, my hanger is straight etc.
I know that 1x drivetrains will never be buttery smooth and quiet in the lowest and highest gears because of the chain line, but even when the chain is dead straight the drivetrain is so loud. I've also read that on clutch RDs the return spring is stronger and more tension on the chain can mean more noise. But I also have a 1x10 on my grocery getter which consists of a ZEE RD, Deore cassette, and XT chain, and it runs much, much quieter (and also shifts better) than my Rival 1.
Long story short, is this normal? Are all Rival 1 and other SRAM 1x11 drivetrains this loud? I see Rival 1 on so many bikes, but if they run this loud on all of them I don't understand how people can ride them and I also don't understand how SRAM had the balls to release a drivetrain like this.
