When moving the chain backwards while bike is standing, I hear some weird sounds.. I made a playlist on youtube and would greatly appreciate some help :(. Video titles give more details.
Should it matter, crank and shifters are Sram GX. Rear is type 3 with roller bearing clutch. Crank also has bearings I think.. I am thinking they might cause the sounds :(
Also, the front shifter is badly aligned. However, I was noticing the issues in the 1x7/8 video (frequent sound + chain bump) even if I lifted the chain so it clearly had no contact with the shifter cage.. I think it is the crank's fault.. maybe the bearings.
More often than I would like I also hear a snapping sound coming, I think, from the inside... I thought it is from the crank and might be related to the sounds/symptoms seen in the videos.
