Honestly, the shifing is not an issue. There is absolutely no differance on the rear shifting. The shifting mechanism on the rear derailleur is exactly the same. The cage is longer for the triple. It takes up chain slack.

The front shifting works great. I don't have any problem at all. I have Ultegra 9 speed.

The front may take a few more minutes to set up. Big deal. A well adjusted front der will stay in adjustment for well over a year as long as you don't clean your bike with a hammer.

One thing about road cycling - It's hard to change tradition with a good idea.
