you guys argue about the most inconsequential things.
If everyone is so caught up with which lever does what, Di2 does have the climbing and sprint shifters for optimal ergonomics.
Debating how fast double shifting is on eTap is silly until you go out and do it. Unfortunately, none of the reviews I've seen have addressed it.


In the debate of which drivetrain is better- I have not tried eTap yet.
But based on Red vs Shimano Ultegra and DA, Shimano is the better drivetrain.

I'll take a DA chainset over SRAM any day and the ergonomics of Di2 are better, imo.
Shimano just runs flawlessly and is so smooth. I just like that feel better than SRAM.

Wireless is a real advantage, and that's the only real reason to go SRAM.
Shimano went conservative with the wire technology but it's hard to argue with absolute reliability of hardwiring compared to wireless.

As road disc comes to the forefront, Di2/hydro integration and eTap/hydro will be interesting.
Shimano has not released a Dura Ace or Ultegra Di2/Hydro lever/brakeset yet. Maybe that's where wireless will come in?

Neither version will be perfect and I know Di2 can muck up and as SRAM goes on sale, i'm sure it will too.

The one thing I don't like based on what I've seen- eTap battery is held on by a plastic flip-tab.
That looks like it's just waiting to snap off.
