Tannus Armor Tubeless is the result of years of manufacturing high-quality multi-cell foam combined with extensive professional riding experience. At the core of Tannus is our patented Aither technology. The minimum internal rim width required for the installation of the inserts is 19 mm. The unique Armor Tubeless design ensures faster handling and unparalleled shock absorption. The flexible side wings provide stability in corners and rim protection. If you get a flat, you can still ride for a limited time.
