Creo Remote Control DIY
- Thread starter Forkliter
- Start date
IMHO this seems only slightly better than just using to top tube power level button. And is not very clean. Will be good to see what the factory solution will look like.
i think if the button(s) on the top bar was one big one as is done on ebike motion bikes we would probably not be talking about this fix. Creo buttons are simply too small and fiddly. but I am ready for THE solution. my guess is there will be a mod in future models or all Creo will include remotes.

Putting the Levo shifter up by the hood works super well. I can rest my thumb on it and easily ramp up or down on the assist level when I need it. My hands never leave the hoods.
However, I’d really like it if someone figures out how to solder the Levo wire to the e-tube wire so we can simply use the left shifter for up and down. I see someone here is working on that...

Had to remove the metal cable guide where the cable enters the frame. Someday I could use a drill to make the hole bigger.

Although if you want to mount the controller by the hood, the shorter of these two would seem to work better than the extender bar above:Had to remove the metal cable guide where the cable enters the frame. Someday I could use a drill to make the hole bigger.

Dazmanturbo - curious if you've taken a stab at this modification and if so, can you provide a more simplified diagram of wiring? Thanks.

I decided to take a shot modifying Di2 left shifter buttons (since the left Di2 shifter is not used in 1x drivetrain), splice the wire and connect it to the LEVO FSR cable, which then connects to the CREO TCU to remotely control the CREO power assist levels. I can report that it does work. While the drawing that @dasmanturbo posted on the second page of this thread (thanks @dasmanturbo) provided some guidance, here is my simplified approach to the DIY. Please note, any modification is at your own risk 
What you need:
- LEVO FSR Cable
- Di2 Left Shifter (I have the R8070 shifter)
The short summary: The Di2 left shifter buttons are momentary tactile buttons and can be used to change the power assist levels. All you do is cut the wire enclosure and connect it to the LEVO FSR cable.

DIY:
- Behind the shifter lever, remove the Di2 shifter button unit (see below). Note: you don't have to remove the lever -- just the two screws holding the shifter buttons to the lever. And make sure you don't misplace the 3 springs.
- Remove the shifter hood to expose the Di2 Top Button (if you have one), and remove the two torx screws to lift the Top Button unit.
- Two wire enclosures will be exposed: One that goes to the the Di2 e-tube junction connector, and the other which goes down the lever to the shifter button unit. All I did was cut/spliced the wire enclosure that goes to the the shifter button unit
- Connect the spliced wire enclosure to the FSR wire enclosure. The FSR wire enclosure has 5 wires (only need to use 3 wires), while the shifter button cable enclosure has 3 wires.
- That's it. Test it out before putting everything back.

Here are the two torx screws holding the shifter buttons behind the lever
Here are the two torx screws holding the top shifter button
Once you lift up the top shifter button enclosure, it will expose two cables. Cut/splice the one that leads to the lever shifter button unit. Think twice, or maybe take a minute to ask yourself do you need the left shifter to work in Di2 setup... before cutting it.
And then connect the cable/wiires from the shifter button unit to the Levo FSR cable.
BTW: If you have enough cable slack, you may just need to remove the top shifter button, and don't have to remove the lever button unit .... because re-installing the lever button unit requires some patience
RE: soldering the wires... I was lazy and just twisted the wires and electrical tape... but i would assume it's better to solder the wires.

A sharp exacto knife would do... but you need to be careful not to apply to much pressure because you'll end up cutting all with wires.... good luck.
The end product in this DIY approach is best solution I've seen so far for those of us who have that DI2 lever there. Way more elegant and simple than wiring the yet to be available Specialized Remote Buttons. But...even though I bet I could handle this project I'd be concerned one false move and I blow out some part of the electronics that make the bike the well integrated machine it is. Would hate to kill my $9500 bike. Will wait for official parts.

What's the significance of the red arrow on the right? I see the left one pointing at the wires that need connecting...Here are the two torx screws holding the shifter buttons behind the lever

That's the cable the needs to be cut (it originally connected the Di2 lever shifter button unit to the top shifter button). You then take that cable enclosure of the lever button unit and connect it to the LEVO FSR wires (which is the arrow pointing on the left).

Wow, that is cool. Specialized should steal your idea.

I highly doubt they will because 1. they're "specialized" and 2. it requires modification to Di2 shifter.
But, my feedback to Specialized (I doubt they care): When I saw the 2021 CREO Remote, it looked pathetically bulky and way to many wires and an item that was designed in 1970. If you look at the 2021 CREO Remote stock item, the buttons are essentially 'momentary switch buttons'. And you can find a whole bunch of momentary switch buttons on amazon. All this DIY did was replaced the Specialized buttons and used the Di2 momentary switch buttons (i.e. the shift lever buttons) and used a much cleaner, simplified LEVO FSR cable than the mess of cables that comes with 2021 CREO Remote. Of course, everyone has different preferences/likes... and may prefer the stock 2021 CREO Remote (and for some reason, it takes forever to be available in the states).
As with any DIY, just know what you get into... but, I'm confident this will work well for the wife ... since all the buttons and cables are passive components. My wife loves that fact she doesn't have to take her hand off the handle bar (uses the left shifter as typical gearing, but for power assist), or even move her hands to find the buttons, and more important... don't have a bunch of wires hanging out her bike. In fact, specialized could have just taken the existing LEVO FSR cable and expand the diameter of the button mount so folks can mount it on the handlebar and that would have looked better. Anyways, I'll get off my soap box and hope the DIY helps those that are wanting something different.

Not having a switch on the bars right from the get-go was a mistake and trying to solve the problem by putting a mickey-mouse switch under the bar tape is a half-a$$ed solution.
I suspect that Specialized will get around to installing something like what taylorpetie did to his wife's bike.....eventually.
