Hi, If you have a digicam lying around, this is all you need to get started shooting some cool clips while on your rides. This is a brand new handlebar mount, similar to the one I use on my motorcycle. Works well with most motorcycles and bicycles. It comes with rubber padding to adapt to the width of your handlebar. The ball head is movable and you can set a suitable angle with it. Standard tripod screw mount should work with almost all cameras. DSLRs can fit, but not advised due to the nature of the size. This is a Chinese product, but high quality. These professionally clicked photos while not shot by me, represent the actual product very accurately. I had sourced this from Shanghai for my motorcycle, loved it so ordered a few extra for friends and fellow enthusiasts. I'm selling it here with a minor margin, to cover shipping, importing, customs and other costs involved.  Frankly, this is a fair price according to me and also easily the cheapest on the market. I don't foresee any issues due to the personal diligence on this order, but if you need any help, please feel free to reach out. Tested successfully on Royal Enfield Classic 350, but frankly it should work on all handlebars as the rubber grip will help. Thanks, Pranav PS: The cycle and the camera are of course not included. You will only receive the mount:)
