I have installed this thing a few times on 2 different forks (which may be the problem). Lately it's shifting around even after I think i've installed it properly. It is the sending unit from a Cateye cordless 7 - and there's a little rubber pad which used to be sticky on both sides that is supposed to sit between the sender bracket and fork. Since it was out of position, on Monday I used some of my daughter's scrapbooking tape on it, and it seemed ok. Today's Tuesday, and it sat in a hot car then was ridden tonight, and it's loose again.
I did use pliers to tighten the zipties - so I'm at a loss for what to try next. Anyone use any good stickum that won't ruin anything but will help in stabilizing this thing?
