The bracket can be mounted, for example, on the handlebars, but can also attach rotated by 90 degrees, for example, on the seat post. The rubber pad helps here also the whole twisting or slipping secured against. If you want to fix the holder to elsewhere: just cut through cable tie, pulling new cable tie through the bracket and fit anywhere else. Alternatively, the Gopro attach this bracket also in many other places: railings, handrails, flagpoles, poles, and, if necessary, they can also quickly remove dab'von or leaving traces.
Conclusion: a small and light holder with many uses, all at a great price. From me, saying a strong buy recommendation!
