The Tannus Armour Tube Insert wraps around the inner tube to provide up to 15mm of additional puncture protection while improving tire stability and ride comfort. The insert helps cushion impacts, stabilize the tire sidewall during cornering, and reduce the risk of rim damage if a flat occurs.
This product requires use of a smaller tube and a minimum 19mm inner rim width. Smaller ends of the listed size range may require trimming for proper fit. This group includes 20 inch, 24 inch, 26 inch, 27.5 inch, 29 inch, and 700c options. Each insert is sold individually.
