Kevlar cord bicycle tyres

With a foldable Kevlar bead

— held on the rim by flexible aramid fiber instead of steel wire, so they can be folded and usually weigh less. This design is more convenient for carrying a spare tire and performance builds, but often costs more than the rigid steel version.

Used on road, gravel, and mountain bikes when weight and compactness matter. A folding bead does not eliminate the need to check ETRTO and compatibility with standard or tubeless setup.
