Hello. I just upgraded the cassette on my Bridgestone RB-2, going from original 7sp cassette to a shimano HG 7spd with more range for climbing.
When I removed the original cassette there was an audible "screech" as it came loose.
When I installed the new cassette, I threaded the lockring by hand to start, hand tightened it with no problems, threads felt fine. I then inserted the lockring tool and began to tighten with crescent wrench. As force was applied, click-type detentes were felt, along with a more mellow version of the original screech noise.
This is my first time dealing with an RX-100 freehub. The screech and those clicks do not feel normal to me.
