I recently replaced a chain/ring, degreased and repacked the BB and greased the crank spindle/DM ring interface. The non drive side pedal click went away for 5 rides returning on the 6th. I'm assuming the click was coming from something I just listed. Odd it came back so soon. Probably has something to do with tolerances. Grease compensates for poor tolerances but sometimes not for long.

 

LBS has determined that the drive side crank is separating from the aluminum insert. SRAM XO carbon crankset. Warranty replacement process has been started. Won't know for a few days whether or not they have any in stock to replace. If replacement will take a long time, I will move the Shimano BB and cranks from my TB2 to the Ripley.

This is my first experience with carbon cranks or SRAM. I didn't want all the carbon on this bike but I had to buy it new as is.

I wouldn't worry, I know people who have been flogging carbon cranks (and lots of other carbon stuff) for years zero problems. Warranty issues can happen with any part.

 

The SRAM Dub bb that came with my XO1 kit was trash within a few hundred miles. The shop was in the process of warrantying it when I realized (at the time, May 2020) it was a $25 bottom bracket. You get what you pay for. I ended up replacing it with a King and have had zero issues since BUT pretty much every different brand of BB requires its own tool. Keep that added tool cost in mind if you intend to install yourself.

 

It will be three weeks before SRAM can deliver the cranks. I hope that's the case. Not a bad result given the current environment.

In the meantime, I will transfer the Shimano BB and cranks from my TB2 to the Ripley.

 

Closing the loop on this thread. The cranks came two weeks early! Whoop! Installed and ready to roll!
