Installing a Turbo Road Remote on a Specialized Turbo Creo SL Comp E5 Road Ebike

By Stan Purdum

When I reviewed my new Specialized Turbo Creo SL Comp E5 Road Ebike in RBR recently, I said that the only thing I didn't like about it was the location of the control unit, which is embedded in the top tube, near the head tube end, and that dislike was because when you want to change modes, you have to take your eyes off the road much more so than if the unit were somewhere on the handlebars. And operating the unit also requires you to take one hand off the handlebars.

But in the reader comment section following that review, several of you mentioned that Specialized has a kit with control buttons you can plant on the handlebars or anywhere you want them. One of you even supplied the part number. Thank you, all!

I ordered the kit — on sale for $51.99 — available both here and here.

The kit came with clear installation directions, and it took me about an hour to do the install. Some of that time was deciding where I wanted to locate the buttons. I eventually settled on putting them under the brake hoods, near where my thumbs rest during normal pedaling. (The hoods are no impediment to operating the buttons, but neither is the handlebar tape, so you can wrap over the buttons if you wish.)

No matter where you put the buttons, however, planting them requires first removing the handlebar tape, and for me, the most time-consuming part of the whole project was rewrapping the bars afterward. I reused the same tape, which went back on without difficulty.

Although the instructions made the installation seem easy enough, I looked on the internet to see if there was a video of someone actually doing it. I found only one (see it here), but that video made the project seem harder than it proved to be.

The wires route internally through the frame, but the Creo the presenter was doing the install on must have been an earlier model than mine, because unlike mine, his didn't have any cutout access on the side of the top tube (in bike jargon, the cutout is called an ICR port — Internal Cable Routing port) so he had route his wires through the ICR port on the down tube where the brake and shift wires also enter the frame, and then thread his wires through the joint where the top tube and down tube connect. He ended up turning the whole bike upside down to accomplish this.

The one useful point I picked up from the video, however, was the benefit of marking ahead of time which wire would serve to move up (+) the mode ladder: off→eco→sport→turbo, and which would serve to move down (-) the mode ladder: turbo→sport→eco→off.

The kit comes with three parts: (1) a remote button connected by a wire to a male jack, which I marked "+" (2) a second identical remote button-wire-jack, which I marked "-" and (3) a junction block with two female receptacles, one marked "+" and one marked "-"; the block's wires went to a connector that would plug into the existing control unit.

In short, to install the Turbo Road Remote:

When on the road, turn the control unit on as usual. If you wish, changing modes can still be done from the control unit, as the new buttons do not override the unit; rather, they provide an alternative — and more instinctive and safer— way to change modes. The unit continues to display as usual, so you can always tell at a glance what mode you are in.

An additional benefit is that the Turbo Road Remote button allows you to move in either direction, up or down the mode ladder. The button on the control unit only moves up until it reaches the top, and then starts over. If, for example, you are in sport mode and want to drop back to eco mode, you have to click the unit button twice to move through the turbo mode to get to eco. With the remote buttons, you can click the down button once and move back to eco.

Though each button is present as a small bulge on the side of each brake hood, they are not at all in the way, and bulges let me know exactly where the buttons are, so I don't have to feel around for them.

As mentioned above, the only thing I didn't like about the Creo when I bought it was the location of the control unit. Now, with the addition of the remote buttons, the bike is darn near perfect!
