Anyone ever seen wired speed/cadence combined into a single wire with a Y-split?

Just picked up Bontrager's best wired computer from the LBS, which also has a wired cadence sensor. I was very disappointed to see that there was only a single wire for most of the length, then it split into 2 wires, with another 8" wire to the cadence sensor and about 12" to the speed sensor. All the wires are also are quite large in outer diameter. This makes it quite unwieldy to work with, and the lengths of wire to each sensor make it pretty much impossible to mount up and work with. I zip-tied the cadence sensor on the chain stay, based on where I placed the magnet on the crank arm. But then the speed sensor wire reached almost all the way to the rear dropout. To place it anywhere else on the chain stay (more forward preferred to get it closer to the wheel spokes) meant the wire had to turn back on itself. It all was going to look very messy. And then the place where the wire split into two happened right at the cable guides underneath the BB. Really no good way to secure it and have it look anything close to a "clean" appearance.

Any tips? If not I guess I'm going to return it and get the next lower wired computer, which is speed only, for $10 less. I don't really care about cadence much right now anyway.

I think that's normal routing for a computer with cadence. You can either wrap the speed sensor around the stay to take up some excess length, or fold it back and forth a few inches and zip-tie the folded part to the stay.

Yeah. You usually can bundle up the excess right behind the cadence sensor and zip tie down so it isn't so noticeable. Mount both sensors where the need to go, pull the wheel sensor wire taught behind the cadence sensor, fold the excess, and tie it down.

Cateye has it. On my wife's bike, I drilled a hole in the bottom of the rear arm. Ran the cable in, over the BB seal, out a hole on the underside of the top end of the down tube, up the side of the headset and around the brake cable housing to the handlebar mounted computer unit. Very clean. It did require the cutting, soldering & taping of the wire in order to feed it thru the holes.

Sounds cool, but I surely won't be doing that to my brand new bike. Say bye-bye to that bike and/or frame warranty.

Well if I had the money I would go ANT+ digital wireless. But I don't so I had to go wired, since analog wireless obviously doesn't work along with my Cygolite front light.
