Holding wheel sensor in place

I have a late-model Flightdeck with the wireless front wheel sensor. The sensor unit is held in place by a tie-wrap type strap and has a rubber shim located under it. Since my carbon fork has a glossy finish and the legs are tapered, getting the sensor on tightly is a bit of a problem.

On a ride this weekend, I hit a bump and it dislodged the sensor, which dropped down the leg. Luckily I was able to stop quickly, walk back and find the shim, and get the whole thing put back and working again (I really needed to show mileage to follow the route sheet I was using).

Anyway, I'm wondering if I could improve the attachment by using some sort of adhesive in addition to the tie-wrap. Does anyone have an idea what could be used to stick the rubber shim to the fork leg and the sensor to the shim?

If you have any thin rubber sheeting or rubber shims, rough them up with sandpaper to take any smooth "glossy" finish off of the rubber. Then when you tighten the ty-wrap, grab it with a needle nose pliers (sideways) right up against the bracket (locking mechanism), and tighten it with a twist of the pliers to lock it in place. Then clip the excess off, and file it smooth, taking care to not touch the carbon itself.

That should hold it in place.

I always use a dab of silicone adhesive (GOOP) on these installations. Forget the shims; just use the adhesive between the sensor and the fork leg and secure with the ties as usual. Allow to dry before using.

This will allow removal if necessary (without harming paint or CF finish) and really keeps the sensor in place.
Today, I believe my jurisdiction ends here...
