Thank you for your response and helping me with some great experienced suggestions! I think at this time I will just replace the cassette and the RD and see how things go. The FD shifts without any big issues and only responds slowly, from the 34 to the 50, on seldom occasion. I am guessing that might be due to the condition of the chain (which I also have purchased new) and maybe an adjustment? When you say, " skips on the chainrings", does that mean when engaged in a particular ring, it loses tension or comes off the gear? Once in the ring, I never lose tension, stays in the ring(s) and pulls great.

The tires are good as they are, but I will eventually change them to a 25 from the current 23, or that is my thought? The brakes/calipers are also in great condition, Ultegra, without any sloppiness. The wheels, Mavic Ksyrium SL (front) and Mavic Ksyrium Elite (rear) and have been checked out and are good to go. I don't know the age of those wheels but those are the models.

I am looking forward to getting these parts changed out and taking her for a spin.

Thank you very much and I hope to be able to help someone out as well, as I gain experience!
