Yes, the Altum LE is lighter. Yes, it has many striking new features and technologies. But the heart and soul of this bike is centered on how it rides. How it leaps into action when you stand up and sprint. How it carves through corners with unrivaled confidence, and disappears beneath you on long, grueling rides. Subtle, evolutionary refinements have long been the Parlee way. The Altum is simply the next step in a lineage of bikes that began with the award-winning Z1 and has continued through the Z5.
