Last week I decided to change the cassette for the anticipated hills of the Chautauqua Gran Fondo. I noticed that when removing the current cassette the lock ring wasn't particularly tight. Frankly, I've never felt the need to put much torque on lock rings incorrectly figuring that the cassette cogs aren't going to fall off or the like.

When I installed the desired cassette (13-28) I tightened the lock ring more than usual. Then I took a trail ride and much to my surprise, the shifting was flawless.

Perhaps after 50 years of wrenching on my bikes, I really should purchase a torque wrench.

Glad you figured it out, Yes, the cassette lock ring needs to be TIGHT. Also grease on FH body(to prevent creaks) and grease on lock ring threads.
