Self-Sealing Bicycle Tube 26" x 17.5-2.125", Black One Size

Innovative bike tubes that can stop punctures immediately and for up to 2-years! The tubes come filled with Slime sealant, which can instantly seal multiple puncture points simultaneously. By lining the inner walls of the tube its gloopy viscosity allows it to mould and move according to the dynamics of the tyre, meaning that it automatically plugs any hole created by being drawn to the hole via suction.Head out without your puncture repair kit and let the tubes do all the work.Seals multiple punctures repeatedly for up to 2 yearsSeals tread area punctures up to 1/8 (2mm) in sizeNon-toxic and non-flammableCleans up with waterSchrader ValvePre-filled with puncture-stopping Slime sealantPresta valve stemCan be easily cleaned with waterNon-toxic, non-flammableDimensions: 26" x 1.75 - 2.125"
