Panzer EVO reshapes their five-sided Spanish tubeless tire inserts with third gen anti-pinch flat protection that is much lighter, tougher & better fitting. The new Evo features an optimized construction that promises better flat protection to will let you run more supple tires at lower pressures without sacrificing security. Plus, now bundled with tubeless sealant for extra value, they hope Evo will make choosing Panzer inserts an even easier pick for cross-country, enduro, and downhill…

With its unique pentagonal cross section, Panzer tire inserts have offered a unique approach to resisting tubeless tire pinch flats when running lower tire pressures. The free-floating design was effectively self-centering to respond to impacts, while allowing tires to freely flex without restriction. Now a new shape and new high-density closed-cell foam make Panzer Evo better in almost every regard for XC, Enduro & DH mountain bikes.

The new Evo insert starts with a new layered GEN3L foam material & construction, developed to increase the level of rim protection, as well as to extend the overall life of the insert, as it is repeatedly subjection to compression and sealant contact.

The multi-density construction takes advantage of new laminated internal reinforcement to improve its overall structural rigidity. At the same time its resistance to deformation & stretching both increase by 200%. All that without actually increasing material weight vs. the original Panzer inserts.


Then the more complex Evo shape comes into play, reducing actual foam insert volume by 20% while retaining key dimensions where it is compressed between the tire & rim.  The new Evo shape is less the pure 5-sided extrusion of the original, now getting wide boxy sections next to the sidewalls, the same self-centering V in the rim bed, and a new channel at the top that allows each side to deform more independently of the whole.


The result of the updated shape is more material for protection in the area subject to the greatest impact & more unrestricted air volume inside the tire, while decreasing system weights by up to 22% (+/-5%) and maintaining an easy setup.

Panzer EVO MTB tubeless tire inserts – Pricing & availability


This next generation Panzer Evo mountain bike tubeless tire insert is available in three different sizes to suit most modern XC to DH bikes. The lightest version is the 29 XC, with individual insert weights of 70g (saving 14% over the previous generation) and designed for 29″ x 2.0-2.3″ tires.

Then two versions are made for wider trail, enduro & downhill tires. 27’5 END/DH inserts weigh 80g a piece (down 20%) for 27.5″ x 2.3-2.6″ tires. And 29 END/DH inserts weigh 90g a piece (down 22%) for 29″ x 2.3-2.6″ tires.

All of the new yellow Panzer Evo inserts are available packaged for one wheel together with a 125ml bottle of yellow Panzer tubeless sealant for 50€ each.

The original black Panzer classic is still offered for 35€ per wheel with sealant, or 90€ per pair of the yellow Panzer Gravel. All versions new & old are available from local bike shops now, through a distribution network heavy on shops in Europe, but also scattered a bit more globally.

    you have to hand it to the bike industry. They convince people to run their tires at such low pressure that is causes flats. then the consumer has to spend more money to add trinkets to keep their tires from going flat. those trinkets add weight so the consumer needs to spend more money on lighter weight parts to compensate for the trinkets. such a brilliant viscous cycle. if only they could convince people to discard their bikes simply because a new “Standard” was released. Oh Wait..

      This is adopted tech from the moto-enduro set. They call them “Mousse”. The Moto guys run far lower pressure. I’ve always wondered what actually happens to the foam once the tire is pressurized. If it’s close cell foam, it should compress, a lot.

      Also, $90-100 for extruded foam? C’mon…

        yes the price of these trinkets is really highway robbery. Fortunately no one is holding a gun to our heads to buy these trinkets. Just run higher pressure in your tyre and your suspension a little softer

      Whatever your perspective, don’t knock it until you’ve tried it – low pressures are magic in the rooty, rocky playground I ride. I’ve had good success going to a 2.6″ enduro casing tire, running at 14 psi front and 15 back. Not too many rim strikes, no flats so far, and amazing performance. If I speed up and start getting more rim strikes, an insert is probably the answer, as the bike won’t settle down at higher pressure. Lower shocks pressures not currently the answer either, as I use all the travel and have bottomed a few times.

    At some point, someone is going to figure out how to essentially integrate the insert’s function into the tire. I like what Schwalbe has done, flipping the casing layers around so it’s three layers on the sides and two at the tread (then adding a puncture resistant layer at the tread). If there was some way to add molded rubber grid structure on the inside of the sidewall, i don’t know, that might be heavier than the foam, but you see what I’m getting at.
