These rims are wide enough to support your tires and prevent the casing from folding over in hard corners. Yet they aren't so wide that the rim takes away your cornering edge. Thanks to the rim's profile and designed bead seat, these work with most tubeless tires. The Spoon series is all about value, and these rims are a great way to add some performance and pop to your Park, Dirt Jump, or Trials bike.
BeadNip technology adds a second set of horizontal "Nips" (in addition to the standard, vertical hooks of rims) to provide additional security for tire beads
The Oohbah profile acts like corrugated steel to prevent folding rims and adds rigidity for sharper handling
Due to the Oohbah profile, which is convex, Spank/Fratelli Industries tubeless tape is recommended as it holds that contour better than many other tubeless tapes
The Manufacturer Spec ERD specification listed uses the less common “ERD+” method. ERD+ is the manufacturer's listed diameter of the rim at the spoke nipple seat and does not account for the height of the spoke nipple shoulder when calculating spoke length. If unfamiliar with this system of measurement, physically measure ERD yourself before committing to a spoke length
