Okay, getting lots of good info here. Just checked my little "stash" of parts and found that I have a brand new Dura Ace bar end shifter for the FD. Just need a shifter for the RD. Like I said, I'm partial to a 10-cassette, but willing to take advice and move to an 11. With that said, I have an opportunity to get another Dura Ace for the RD, marketed as a 9-speed shifter, or a Microshift 10-speed. Which one is more desirable, if there is an appreciable distinction? Again, I'll be using friction. Thank you!
