Need Photos of WIRED PT installs

I need help finding pics of wired PowerTap installations. Trying to figure out how to run the wire from my sharkfin up to the handlebars. Right now it runs up the driveside seatstay, wraps around the rear brake cable a couple times as it travels up the top tube, then wraps around cable housing up to the stem.

Problem is, the part that wraps around the brake cable contacts the aluminum top tube on rough surfaces and makes a "pinging" sound. The sound is getting annoying.

I'm looking for alternative ways of running the wire.

Find some tape that matches the color of your frame and tape the cable to the bottom of your top tube.

I ran mine up the seat stay as you did. Then I zip tied the wire to the cable housing from the rear of the top tube to the brake. Then ran the wire under the top tube and used zip ties to secure it. I then rapped it around the rear brake cable housing from the top tube to the bars. I mounted the computer on the stem.

I have mine mounted on my chain stay then the wires (shark fin and cadence) go under my bottom bracket and under my downtube up to the headtube where I started looping it around one of the cables.

Not a detailed picture but you can kind of see the shark fin.

I used zip ties for the shark fin, then the clear strips of tape that came with the PT. The wire runs up the left seat stay, around the seat tube, and along the bottom left portion of the top tube, then coiled around the brake cable housing to get to the bars.

The cadence sensor is on the left chainstay, and runs up the bottom left part of the down tube, then coils around the FD shift cable housing.

The clear tape makes for a pretty slick install--having a triangular top tube where you can hide wires doesn't hurt either.



Here's a better shot for seeing the wires and which housings they're wrapped around. And you can just barely make out the cadence wire on the down tube--very important not to block that Pinarello logo.

Pics are either on this forum or WW but from the stem: wrap around front brake housing, jump to the shift housing braze-on on the closer side (I run the cadence sensor to the other side) - be sure to leave little play in the wire, zip tie to the cable to the brake housing and the downtube, right before the shift housing brazes. Run the cable the length of the downtube using one or two of the clear tape bands you get and another zip tie at the base of the downtube/BB area. Run the cables loosely over the BB cable router and mount your sharkfin and then your cadence sensor (use the zip tie for the cable sensor to hold the other cable in place). Ends up being very clean.

The fin shows up a little better in this picture.

Interesting... I'll have to try mounting the sharkfin to the chainstay. That seems like a better place on my CAAD9 anyways, since the seatstays run at odd angles and bends. Thanks for the pics, guys!

It's not the appearance I'm concerned about but the annoying dinging sound the wire makes when it vibrates against the top tube.

thank you for not using the white garage door.

I did it a little different. I ran both the cadence and shark fin wire up to the top tube via the non-drive seat stay using zip ties. Once both wires were at the top tube I neatly taped them together to form a single strand, then used two well placed zip ties to hold it below the top tube all of the way to the headtube. At the headtube, the strand is loose (it looks like another rear brake cable) enough to move the bars, and then meets the PT mount. Any excess wire is hidden under the mount by circling the mount and wrapping it with one zip tie. It looks clean. Hope that helps.

I have mine wrapped around the seat stay, wrapped around the brake cable and brake housing and to the stem.

I'll be going to frame building school and may drill some holes in the tubing and run everything internally.
