Crux presented by RL Action and Alias Lab Crux defined: a particular pint of difficulty. This singular word precisely describes the riding of the film. Each and every line that the freatured athletes, Ryan Leech, Dylan Korba, and Thomas Ohler ride has a crux. These three riders, aggressively pursuing Leech's Manifesto Style, execute mind-bending feats of bikes mastery. Combining shear difficulty with an elegant and creative style, Crux is a film that redefines technical riding standards.
