Just installed this Sunrace CSMX8 cassette. 11-46t, replacing my stock SRAM 11-42t. HG hub. Spacer installed.

    The only adjustments I made were a small turn of the barrel adjuster to index, and maybe a quarter/half turn of the b-screw to accommodate the slightly larger cog.

    Why is it so loud when dropping into the smaller cogs? I haven't ridden the 11–42t in a while, but I don't recall it being that loud. Perhaps just slightly wider spacing of the cogs? Is there something else that could be wrong?

    Why so loud?

      Ride it. How does this sound while riding under a load.? It sounds to me like the sound is vibrating through the spokes like a guitar string.

    2. Sounds alright to me. Sram can be loud, and paired with a different brand cassette can make it louder. One concern may be the hub bearings. Check for play in the hub.
