OK, lots of people want to use Trumark bands, as those are widely available pretty much everywhere. There are two obvious ways: 1. Over the top, just as you would attach flat bands - yes, it works, and yes, it holds. 2. "Gipsy style" - a bit of paracord, tied through the hole, with a knot about 1,5 cm away from the fork. Then you use the "knot in tube" method to secure the rubber to the paracord.
