Trek Speedtrap Sensor Install

[Pookie4G]

Has anyone installed the speedtrap sensor with the digital wireless computer? The computer came wit ha speed sensor and magnet and a cadence sensor with magnet. Do I need to install them if I'm using thei ntegrated speedtrap in the fork?

Thanks

I wondered the same thing myself.

I tried the install without the included SPEED sensor (the one that came with the computer) and the computer would not pair with the Speedtrap sensor in the fork. I got an ERROR message.

When I tried it with the included SPEED sensor, the unit paired no problem.

I don't think it is supposed to work like that though. The whole purpose of the Speedtrap integration is to not have the SPEED sensor mounted to the bike, right?

From the Trek site:
Integrated Speed Sensor

An industry first. Our new Speed Trap™ technology allows you to put a 2.4 GHz wireless sensor directly into the fork leg itself. The result is a clean look that preserves aerodynamics and a sensor that installs in seconds. Say goodbye to the zip ties. Speed Trap technology is built into Bontrager's Madone-specific Race and Race Lite forks, and is found on Trek Road models 1.5 though Madone 5.1.
Note: Fork includes integrated pocket, but Speedtrap sensor unit must be purchased separately.

So I would conclude that:

Looks like you have to install the sensor into the fork for it to work. The sensor is not there when you buy the bike, just the ablity to integrate it is.

I bought and installed the sensor for the fork.

I'll run it back and have the LBS take a look.

Probably just a bad sensor in this case.

It was the stupid magnet! Of all things. The LBS switched it for an old Cateye magnet (after trying new sensors, batteries...) and it works perfectly. The TREK magnet was not strong enough to register in the sensor when it passed on it's rotation.
