Tannus Armour Tyre Liner

If you're getting punctures (particularly on an e-bike or cargo bike), this is our preferred method of reinforcing your tyre.

It's a foam layer that sits between your tyre and tube, and protects the tube from pieces of glass, nails and other road garbage.

Note that you may need to use a slightly smaller size of inner tube, due to the room that the Tannus takes up inside the tyre.
