Well, the bike is dialed in and it rolls fine indeed. Shifting will take some time to get used to. My neighbor is a bike mechanic. He doesn't do it for a job anymore but he did it for many years. Anyway, he was helping me dial my gears in, and I asked him to help with my rear derailleur, as it was bent during shipping. He told me to hold on a second. When he came back he installed this older derailleur that had never been used, and was top of the line in its day. It did improve my shifting X100. Thanks Randy!
