Thanks once again for all the info. Wheels that I have are Gipiemme Tecno 024. From quick google search, they are 8,9 or 10 spd wheels, so no go on the 11 speed cassette. Other than learning how to do things myself, one more reason for wanting to build myself is that I dont have to spend lots of money right away all in one shot. I get that in the end cost between building myself and buying complete bike will be about the same, but if I am to do this I would take my time. This would allow me to space out all the purchases over longer period of time, and look for some deals perhaps. This way it makes it easier on the wallet as I wouldnt blow 2,3, $4000 all in one go. It makes it easier to spend that much over longer period for me at least.
