Building Brandon Semenuk’s Red Bull Rampage Bike

Brandon Semenuk’s 2021 Red Bull Rampage build is the bike you’d expect a five-time Joyride and three-time Rampage champion to ride. With big travel, and big trick potential, his custom 27.5 / 26 mulleted Trek Session is set up with a one-of-a-kind BlackBox AXS drivetrain, and a 190mm single crown RockShox Zeb Ultimate. Master mechanic, Sean Murphy, of Fluid Function in Squamish, BC assembled one of his two builds that he’ll be traveling to Red Bull Rampage with, as he seeks an unprecedented fourth title.
