Description Michelin's A4 Airstop Tube is ideal for training and recreational riding. Available in size 29" x 1.9" - 2.1" (48/54-622 ISO), with a 40 mm threaded Presta valve stem. 230 g.
Note: If your rims are designed for Schrader valves (like on a car tire), you can use "Presta Stem Savers"—metal sleeves that fit over Presta valves to provide a snug fit in Schrader-sized valve holes.
