Bike Mount ABM01 for PR and CR series headlights, compatible with tubes of 22.2 mm, 25.4 mm and 31.8 mm diameters Made by glass fiber and nylon material, light and durable Right-Left rotation angle: 15°
It gives a great light and good possibilities to adjust the strength of the light. Seems like good quality!
The cons: I would prefer to switch between road and mtb mode with the wiered button, instead of just strength of the light. The mount is also a little bot flexy, you can move the light a few 1/10 mm in all directions. No problem on the roadbike, But perhaps for mtb over time.
