So I just upgraded my RW4 with a set of Tannus Armor inserts and since they use a smaller inner tube, I no longer need these factory tubes. They have 113 miles on them and still hold air without issue.

No charge for the tubes, you cover shipping. Pretty certain I can get them both in a small flat rate box. Or if you are located in Portland Oregon area (or the north coast) we can meet up.

Cheers!
