Tech features:
Intended for enduro and downhill use, the Radium shorts are constructed from the same fabric as Fly Racing’s Lite Hydrogen MX pants. Like a quality pair of motocross pants, the Radium uses a full-mesh liner, making the shorts extra comfortable for downhill riders who might not always opt to wear a chamois. For enduro riding, the Spandex panels stretch to provide an added range of motion.

Perhaps the Radium’s most valued feature is Fly Racing’s patented 2-D buckle system. Our biggest gripe about biking shorts is typically the lack of adjustability in the waistband, and if you can adjust the waist, it doesn’t remain secure. If you experience weight fluctuations or accidentally purchase the wrong size, the Radium can change waist sizes with you. You will also appreciate this if you decide to don hip pads for the bike park or add base layers in winter.
