I believe this explains my current issue. As you probably remember from my recent thread, I put an 8 of 9 cassette on an RX 100 hub, with 9-speed shifters.
Everything seemed fine in the city, but getting out on the road, some chain issues showed up, with bad shifting. After racking my brain awhile, I realized my old 6-speed chain must be the problem. 😏
The crazy thing is, I had a brand new 9-speed chain on the counter, ready to buy it, where they helped me set up my rear wheel. The mechanic said my chain was fine, and even measured it for stretching, and I said cool, I'll save a few bucks. But obviously NOW, I should have realized and mentioned, that my bike was previously 6-speed, as the chain still is. 😊
Not the mechanic's fault, lol, but a lesson learned for me. 😉
