So in this chart here. The red highlighted ones are not usable. The 50T can shift into the 2 largest but it's severely cross chained so I don't want to use it. The 34T red highlighted, The smallest two are cross chained. The other two rub the front chain ring a little It's not a constant rub but every full rotation it maybe touches it once. Should I just not care and use it anyway. It makes an annoying sound but worse that can happen is the chain wears out faster and the ring gets scratched on the inside. Who cares right?


I have a gap between 3.9 gear inches and 4.6. It's a bit annoying because I'm either spinning too fast or too slow.
