Re-tape a tubeless rim
A rim shaped to seal with a tubeless tire and sealant, no tube needed. A raised bead shelf locks the tire bead airtight; a center channel helps mounting. Tubeless tape seals the spoke holes. Hookless rims: 72.5 psi (5 bar) max, approved tubeless tires only, and observe the rim maker's minimum tire width.
