Tannus Tubeless is an insert that sits between the tire and the rim. It offers puncture resistance, comfort, and enhanced riding capabilities.

Tannus Armour is made of a patented material called Aither. It’s a high quality foam-like polymer that offers vibration damping, a smoother ride, and puncture resistance.

150g for the 27.5, 160g for the 29, and 70g for the 700 Gravel. To give you an idea, a 27.5" tube weighs about 160-190 grams, so this is lighter than most tubes even!

All you'll need are tubeless specific rims and you'll be all set! Make sure that you tape them well, a poorly taped tubeless system has more flat issues than anything else out there.

You can use any tubeless valves. This is made possible by the flexible wings that create two chambers within the system. You can put the sealant in, and the holes in the insert allow the sealant to pass through without getting stuck on one side of the insert.
