Anyone muck about with reprogramming shift levers in Di2?
I noticed the Di2 shift lever functions are completely remappable using the Shimano E-Tube app, at least for the new 12 speed Di2. I'm curious if anyone ever tried something other than the traditional shifter configuration? Cool that you can do that, even if it's not necessarily useful for the average person. : )

Doing it right now on a bike I am building up.
This is a useful website: https://bettershifting.com/di2-e-tub...and-downloads/ |
After using STI levers for 16 years, I wanted my then-new Di2 bike to shift in the same manner -- so I did not get creative with the programming. I'll bet virtually all Di2 users stick with the standard configuration. On the other hand, I have used the top-of-hood auxiliary buttons for a couple different purposes over the years -- at first they were secondary rd shifters (left button UP the cassette, right button DOWN the cassette), but now they are programmed to flip the page on my computer screen.
|
I set my Di2 (11sp) so that I only shift the right lever. I never use the left one.
|
Thinking about it. I have an 1X XT system on a my hard tail, with a SRAM 1X system on my FS. The SRAM levers operate the reverse of how Shimano works, but I know I can swap the action in E-Tube for my HT. Might do it this fall when I ride these bikes more often.
|
I use use the right shifter almost exclusively. However the one or two times during every ride I want to get immediately to the big or small ring with out going through the cogs on the rear just makes it hard to want to have the paddles on the left shifter do anything else.
With the buttons underneath the top of the hoods that you can assign to control your Garmin or other device if you have D-fly for your 11 speed or less Di2, I haven't even seen a need for any other things to re-assign the left shifter to. |
Right side normal up and down but left lever shifts to big ring and button cassette down. Top buttons Garmin.
|
I have programmed the top "hidden hood" buttons to shift the rear derailleur in either direction, but in all honestly I rarely use them. I should get the wireless module so I can flip Garmin pages.
My time trial bike is in "full syncro" mode, so the buttons only shift up or down the gear range, the front derailleur is completely controlled by the Di2 brain. |

Auto-shift? It doesn't shift for you. You still tell it when to shift.

Personally, I hate full synchro. Why? I almost never shift from a chainring to another at the same speed / time and on the same rear gear so I like to keep control of that. I don't need the small chainring often anyways, except when I ride in the mountains. At the speed I am going, my 52T offers plenty of range. |

Totally worth the small cost. You'll also get a Di2 battery level readout on your Garmin, as well as a gear position indicator. The latter is surprisingly useful if you live in a hilly area: when you're on a really steep climb, a glance at the computer will indicate whether you still have a bailout gear available.
I love having the battery % and not having to screw around with a color coded light under my stem. |

Do you have a Garmin without touch screen or something? It's at least as easy to change pages by swiping to either side as it is to find a button.

The other thing that I recall from the Garmin (but not avail on the Wahoo) is that, after a ride, I could see a screen which showed the number of times each derailleur was shifted. Not essential, but kind of fun. |
Being very much accustomed to Ergo levers before I got a Di2 setup, I seriously thought about remapping the buttons to be more like Campy since early on it was very easy to miss-shift by pressing the wrong buttons. But ultimately decided against it on the grounds that there would still be a learning curve to get comfortable with new shifters anyways, might as well keep things simple and just get used to the default which works perfectly fine. And a few more weeks of riding later I had no more concerns, just took a while to build a new shifting habit.

Wow, I'm glad this thread was started. I just took delivery of a new bike yesterday that came with the new Ultegra Di2 semi-wireless system. It's my first foray into Di2 and I was trying to think of what I might use the hood buttons for. Good suggestions here.

I didn't even have to program my Wahoo/DA12 speed units for the hoods to control my Wahoo. Just connected so I could see the gears on my screen (which is so much cooler than my super old DA with the little red indicator on the wires) and after reading this thread I tried using the hood buttons and it works! Super slick and not having to take my hands off the hoods to control the screen (great to move between GPS and the main screen). Will be awesome in colder months when using gloves. |
I configured my GRX with full synchro. Both right shifter paddle buttons are down, both left shifter paddles are up. The top (inner) buttons are inverted. So if I ever lost one side I'd still be able to shift up/down.
I did tweak my ratios a bit, I smoothed out the rear jump ratio (it's a 2x configuration). |

Super slick and not having to take my hands off the hoods to control the screen (great to move between GPS and the main screen). Will be awesome in colder months when using gloves. - left shifter = downshifting - right shifter = upshifting ...with lower levers for the rear derailleur, and the upper levers for the front derailleur. I mostly want a bit more symmetry in shifting between hands; right now I do 85% of my shifting with just my right hand. I'm also about to try out the fully synchronized shifting for the heck of it today as well. |
On 12-speed bikes I tend to set the left hood button to "function". It'll then act just like the button on the rear derailleur, so you can enter adjustment mode / Bluetooth connection mode / change shift mode without getting off the bike ;-)

I played with it at first, but quickly returned to the standard configuration. It's perfect for me. Hoods (hidden) buttons are set to shift and downshift my RD when I am in ''fake TT'' position. I know a lot of us are using them to jump from a page to another on our computers.
