Yep, the joys of the mountain bike industry making new proprietary non-standard parts for us to work with haha. If only these integrated one-piece bar/stem combos had a standardized bolt-on interface, then we could make an adapter that works with each, but since they're all different and most have adapters for action cameras, we started with an adapter for that universal interface, and point people to their specific bar manufacturers for proprietary adapters. We will start making our own adapters for each of these unique aftermarket options eventually as we grow and have enough demand to justify low-volume parts, hopefully soon! As for rubber straps, we very specifically avoid that because they simply do not hold anything tight enough to meet our performance needs on trail, and most of these integrated bars don't have a straight section to clamp to, meaning the light would then be off-angle perhaps in multiple axes, basically just creates lots of compromises. At any rate, more stuff is coming!
