To add to your thread. I've used the Goodridge pressure switch banjo bolt on several bikes and have only had one failure on a bike. But that seems about par on any device. After swapping with a new one, the old one was about a year old, no more problems. I've got them on my Paul Smart with Sato rear sets right now. You might consider adding Sato, Ducabike, and Aella Casuno for some nice rear sets.
