MICHELIN B6 Protek Max inner tube

the innovative michelin protek max inner tube is able to prevent air leakage in the event of a puncture. thanks to its knobby surface, the protek max compresses and closes the hole in the event of a puncture where an ordinary inner tube would enlarge the hole (balloon effect). the self-sealing effect is additionally enhanced by sealant in the tire. the protek max inner tube holds air for about twice as long as the classic michelin airstop. Features: - Ultimate puncture protection thanks to integrated sealant - New shape makes assembly easier. - Ideal for all touring cyclists, advanced puncture protection. Specifications: - Type: Inner Tube - Size: 27.5 x 2.40 - 3.00 - Valve Type: Schrader valve - Valve length: 48 mm - Material: Butyl
