Kenda’s quick seal bicycle tubes are a sound choice for bikes that need puncture-resisting dependability without a big weight penalty. In contrast to their bulky thorn resistant cousins, the Kwik Seal is a conventional butyl tube containing a sealant designed to seal holes up to an eighth of an inch wide.

• Contains a liquid sealant that will seal a puncture in the tread area
