Solid Action Camera Mount for Bike & Motorcycle
Picked up this SmallRig double ball head magic arm with clamp for my DJI Osmo 360, great for mounting on bicycle and motorcycle handlebars. Clamps tight to bars up to 54mm with non-slip pads, no wobble even on rough trails; the ball heads adjust quick and hold the camera steady for smooth footage. Super sturdy aluminium build, easy to swap positions mid-ride. Perfect for action cam users on two wheels—stays put through bumps. 5 stars!

Perfect for tilta ring grip + monitor
I’ve been using this clamp to mount my monitor to my tilta ring grip, and it’s been an outstanding addition to my gear. The clamp holds firmly in place, even during intense movements, and the double ball head provides excellent flexibility for adjusting the monitor to the perfect viewing angle. The build quality is solid and reliable, giving me confidence that it won’t slip or fail during a shoot. The non-slip threads are a thoughtful touch, ensuring a secure grip every time. Despite its sturdy design, it’s compact and lightweight, making it easy to take along to any shoot. For anyone looking for a reliable and versatile mounting solution, whether for a monitor, light, or other accessories, this is an excellent choice. Highly recommended for its functionality and value!

Brilliant - wish I'd bought one sooner
I have to say that upon receiving this item I was surprised by the physical weight of the package. Upon opening the box it was extremely well packaged against damage, once out of the protective card packaging, the reason for the weight become obvious. This clamp isn't a cheap plastic clamp, it's made of metal and looks to be well engineered, of course there are a couple of plastic parts but nothing that, should they break, will have any effect on the clamping mechanism. While I haven't used this "out in the wild" as yet, a few test clamping it to a selection of things aroung the home, it works as it should. Am I happy with it? - Yes Would I buy another? - Yes if the need arises Would I recommend it? - If you need a versatile clamp, then it's three yes's from me.

Super handy!
I really love this smallrig clamps. I use them for all sorts. They’re tiny, strong, durable, reliable, stable, and really easy to use. I’ve used mine for mounting MIDI controllers as part of a live music setup, mounting cameras to lighting truss for filming gigs, and getting microphones mounted to desks/pianos, etc. I’ve got three so far and will probably be buying more!

Se trata de un producto de excelente calidad. Perfecto para pantallas Led, cámaras de acción, monitores.... Tal y cómo puede verse en la imagen, las cabezas giran en un mismo plano, de modo que puede limitar algunos movimientos. El hecho de que las cabezas no roten y se trate de una construcción tan sencilla hace que el precio sea fantástico y que la sujeción sea más eficiente que en algunos brazos mágicos. PROS: -Calidad profesional. -Precio económico -Perfecto para pantallas Led, monitores, cámaras de acción, flashes o lo que se os pueda ocurrir. CONTRAS: -Como las dos cabezas tiene la misma orientación el movimiento es en un único plano. En ciertas circunstancias puede ser insuficiente para conseguir la posición deseada.(Para la mayoría de las situaciones no supone un problema) Lo recomiendo 100% Añado que el servicio post-venta de Smallrig es ejemplar.
