Cheers guys - must admit, we are so shocked by the quality - the videos have lost LOADS of quality on upload, it looks amazing when it has been downloaded from the camera straight to the laptops.
It is one of these babies....
It's pretty tiny and sits neatly on a helmet mount/goggle strap. Only cost £200, which is pretty good for the quality and size.
There is a whole thread about it
here which will be worth a read if you are looking at getting one.
@bob - yeah, I bet you're really noticing the change to FS! I started out riding a FS and then got a HT after. That was a bit of a shock to start

Now I ride the HT's as much as possible and then, when I get back on the FS everything feels SO easy - it's amazing (and dangerous heh heh) how they just let you blat over everything without thinking too much.
I love that Atherton vid - all the urban DH courses are definitely my idea of fun! I'd love a go one day.
This morning - 3.2 mile run
