This latest edition of Raw 100 pairs series veteran Rupert Walker, the man behind Brandon Semenuk's lauded cut from last summer, with Kamloops-based mountain biker Matty Miles. As with anything Walker touches, this Raw 100 has the special X factor that always makes the end result more than the sum its parts. Miles's riding is fluid and fast and Walker's filmmaking is just as dynamic – and then some. As always, plug in some headphones and bump the volume up a few notches.
