While I’m a big fan of converting older 26″ MTB wheels to tubeless, I have found that if you let the bikes sit for a month or two without riding, the bead will unseat and the tires will go flat. Here in the Southwest, that means that the sealant usually dries up by the time you’ve noticed. I still believe that a tubeless setup is crucial if you have a bike you ride a lot, but when you have a few vintage bikes in your fleet that don’t see as much regular rotation, that can become a lot to manage. Once the bead breaks and the sealant dries up, you must completely clean the rim and tire out to re-seat it. Not ideal!
A few weeks ago, while inserting Tannus Armour Tubeless rim protectors into my 29er, I noticed the brand also makes Tannus Armour Inserts, designed to be run with inner tubes. These inserts are very similar to the tubeless inserts but don’t require the upkeep or regular mileage that tubeless systems demand, particularly with vintage rims.
Last week I posted my Yo Eddy! restoration and, after I shot those photos, I got a few flats from thorns. So, instead of resorting to my normal tubeless conversion, I decided to give these Armour Inserts a try.
Let’s check out what that entails below!
