BikinFool, Thanks for the responses. Helping me think this out. I just looked up the tires Michelin Dynamic 700x23. Your right I should ride it more and get use to the bike. The issues I was was feeling with the tires/rim was they didn't seem to handle hitting cracks and rough patches on the road very well. Having full suspension for the last 5 years definitely probably makes it feel a bit more off. I felt like they were going to bend on me or maybe I was just worried they were. I was trying to avoid these obstacles but is seems the bike lanes in SD are not all in the best of shape. With the crank I just read a bit more into it, it is possible my mountain bike crank is a different size than my road bike, giving it a different feel. I'll check out that book. I need to learn the overall mechanics of a bike and it's components and that will give me a better overall understanding. No I am not looking to just spend money, I just want a smooth fast ride.
