Not sure what your hangup is with cable ties. By the time I mount a wired unit, it's going to stay there and not be switched from one bike to another. It just takes a few more minutes to make sure the ends of the ties are oriented so I don't see or grab them regularly.

But if you want something with an O-ring mount (and are you really going to twirl the wires around the fork??), is there some reason you're only looking at Sigma? Other manufacturers made these, and you could be looking at Cateye, Planet Bike, etc.
