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!

They are simple and effective
Bought to mount a pair of speakers to a monitor stand and they are perfect. Strong and sturdy. Great product.

Superbly made clamp.
I bought this clamp to hold a Dewalt DCE088G laser to an extending support prop. You can purchase dedicated laser poles with an adjustable plastic platform but they are 3 or 4 times the price of this superbly made, and very strong, ballhead clamp. It easily holds the laser and once mounted onto the prop, it is absolutely rigid. It can of course be mounted to any tube up to 54mm diameter but I wanted to use the floor to ceiling prop to hold the laser rather than a tripod which gets in the way in confined spaces and is limited in height. The prop extends to 3m, which is higher than any of my ceilings. This little clamp is beautifully made, solid metal throughout with rubber lined clamp heads which grip the prop shaft superbly. Highly recommended bit of kit which belies its price and size.

Great bit of kit but clamp for about 30mm max diameter
Real quality bit of kit, all metal apart from Gopro bracket which is absolutely fine and expected. The only down side for me was I was hoping to fit this on my car roll cage which is 45mm in diameter, while the clamp does go around the roll cage it's not fully secure as the jaws are just not long enough and could be pulled off. For a push bike etc this a great price of kit.

Light but sturdy, large clamp
Light weight but solid mount, extremely flexible. Clamp is big so no use where room is tight but you can attach it a variety of wide surfaces. I've fitted mine to bike handlebars with no problems

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.

Ce support se fixe un peu partout. Un vélo (guidon ou celle), un skate, une poignée, une porte, une grille, une tringle, un pied de table. Il convient très bien pour une caméra sportive, mais peut aussi servir à accrocher une lumière, un écran, ou tout autre matériel. La fixation est solide. Elle tient bien en place. On peut l'accroche selon plusieurs angles et directions, c'est nickel. Très polyvalente et un bon rapport qualité-prix. Je suis ravi !
