Hello. I live in a small remote Alaskan town and have started to do repair work on bicycles as there is no shop here. We only have about 15 miles of paved road and many miles of bumpy dirt roads. Most people use their bikes as transportation and recreation, mountain biking isn't a thing as we live on a former glacial moraine and it is pretty flat. I purchased a Park Tool TS 2.2 and was wondering if I really needed to get the centering tool. Mostly I just want to fix out of true wheels so people can continue to ride their bikes. I am self taught and have crossed the country on my bike but have little experience with this tool. I always wanted one and could use some advice from anyone willing to give it. I am ordering a wheel alignment gauge and think perhaps I do not need both. Thank you in advance.
