The world of mountain biking never fails to amaze in one way or another, whether providing unique inspiration to get back on two wheels or leaving the rest of the world staring at something that never should have been possible.

The past twelve months have certainly been no exception to that rule, throwing up more surprises, highlights and heartwarming tales than most can keep track of.

Happy new year folks. It's certainly been one hell of a ride!
