I'm obviously new to this and I've noticed that i've bent inward a little a couple of teeth on the largest sprocket and there's also a couple of teeth that slightly look like there bent inward on the cassette. On the sprocket it also looks like that when it occurred it also took some of the paint and some of the metal from the tip of the teeth as it bent in . Can someone tell me if i did this by not shifting correctly? Is there something wrong with my bike? What's the proper way to shift a bike. For example is it imperative that i go from the next gear up slowly one at a time and so on with the sprocket gears. I would really appreciate any and all suggestions and advice.
Thanks Kenji
