I've gotten good at wrapping drop bars, using conventional cork tape: You start at the end and work your way up, keeping the tension even and watching the overlap, and it works perfectly for me.
But the H-bars on my Bike Friday have aways been a challenge. They're smaller and more finicky to wrap, but that's just a matter of time and practice. Specifically, getting the intersections at the bar joins to wrap cleanly has always been a problem:
Over time, the tape will invariably loosen because of this.
Can anyone suggest a method for doing this that will stay for longer? Should I wrap the main bars separately from the vertical bars? Is there some special secret way to do this? Or is this just a downside to this kind of bar?
Edit: I wrapped the bars from the top of the barend down to the bottom, then getting the main handlebars. The below picture shows the problem area; note the separate piece of tape.
