I’m after an adapter like this, it lets the camera sit the right way up, but also point skywards, almost likes its trying to film chin. Then when sat on bike, and in particular descending it gives a perfect view of trail, bars, and a bit of toptube. It came with mates Hero HD, but nothing of the like with my new Hero.

Also findable on eBay if you search for go pro adapters

Stick with the genuine bits and avoid the cheap junk on eBay. Some are very brittle and don’t fit well with genuine stuff. Some are ok but it’s a lottery.

Why? Fitting it upside down directly into the chest plate, and using the rotate image function, puts the camera in exactly the position you want, without the extra flexibility or potential for damage/failure as using additional mounts.
