Season 2, Episode 1. Uploaded by Red Bull. The second season of Mountain Bike Chronicles is finally here! In the premiere episode we head over to South Africa for the first stop of the UCI Downhill Season. Pietermaritzburg is known as one of the hardest tracks on the mountain bike circuit, but that doesn’t stop the 2011 winner Aaron Gwin from approaching it with ease. After recapping all the action from last season, we get the results from the first race of the year.
