[MENTION=915]RonH[/MENTION] Since we're getting into the details of the build now, what are your plans for the rear wheel? 11 speed cassettes need a wider freehub than 8/9/10 speed, and freehub swaps aren't always possible. If you are lucky enough to be running Mavic wheels all you need to do is remove the ~2mm spacer behind your cassette and voila, 11 speed freehub. Any other brand hub won't be as simple.
