At only 350 grams, it's light, strong, and it features a semi-aero profile for quick accelerations and blazing speed. The Alpha rim also uses Stan's BST technology for easy tubeless conversions, while its wide inner profile and lowered sidewalls boost tire volume for enhanced traction.
Features & Info
Stan's Bead Seat Technology
Stan's NoTubes BST design creates a tight tubeless seal between
the rim wall and tire bead. The inner rim wall is the same size and shape
as the tire bead. It's also shorter, which increases the volume of the tire giving you better traction.
