Tannus

Very top quality

Very happy no more flat tires problems

So far so good. I could easily inject after demounting the valve core through the valve stem. Small amount is enough.

impeccable experience

I carry as a final backup for my tubeless MTB. It saves a lot of space&weight in my seatbag.

I saved approx. 2x142g (=284g!!) from my 9 yo daughter's race MTB.
Holds air better than latex. She rides with ~30 ml Tannus sealant. So far so good!

Excellent product and reliable seller. Installation is slightly more demanding than a standard inner tube, but by following the instructions, it’s straightforward. I recommend ordering a compatible inner tube together with the Tanus insert to avoid sizing issues.

Produse excelente

Zatial super

Good customer support
Foam insert has little bit more weight than specified.

Amazing i did order for both of my bicycles and its tooks me 10min each one to mounts i am using every day for now i am happy worth every penny to spend

Super

Installed on my ebike (26" rear) for daily Vancouver city commuting. The puncture-proof confidence is unbeatable for potholes, glass, and urban debris.
​The Good:
Perfect for e-bike abuse - rear wheel takes constant torque (750W motor), and these hold up like solid tires without the harsh ride

Fills slightly harder than regular tires, but that's the trade-off for zero maintenance. Still comfortable without the rear suspension.

Installation Reality Check (Critical Advice):
HIGHLY recommend buying the P-Tool (https://tannus.com/products/p-tool-pinza-montaggio-copertoni-airless?pr_prod_strat=pinned&pr_rec_id=9d30d58ee&pr_rec_pid=8930268545361&pr_ref_pid=8932553195857&pr_seq=uniform) as the included plastic tool will make you work hard.. brutally hard without it.
Key hack: DON'T push pins where instructions show! The rim lip blocks from below, making it impossible (you'll just get tired and frustrated). Instead, push slightly offset so the pin bends and snaps into the channel see my illustration below or better buy the damn P-tool!
​
I did it solo (skipped gym that day, lol), but worth every sweat drop. Tannus team: update instructions with this trick!

Waiting for 26" x 3" version - would be perfect for ebikes like mine. Fingers crossed!

Bottom line: Game-changer for any hard working e-bike. Buy it, get the P-Tool, install smart. 100% recommend

Satisfied by the service. Thank you.

I’ve just installed them on my gravel bike. I have Zipp 101 XPLR rims and Michelin Power Gravel 47-622 tires. I didn’t need to cut them, they fit perfectly. I used a 26" inner tube on the front wheel and a Schwalbe tube on the rear, which is compatible with 27.5", 28" and 29".
I haven’t had much time to test them yet, only a few days of commuting rides, but so far everything seems fine. I was worried that rolling resistance would increase, but I don’t feel like I’m riding slower or with more effort.
So far I can mention only one downside: the way the product is packaged. Because they are folded, when you take them out of the box they are deformed. I recommend inserting an inner tube inside, inflating it, and leaving it for a while so it can return to its original shape. Otherwise, it can stay twisted under the tire and create bumps or deformations. A possible solution would be to insert cardboard or another material inside during packaging (where the inner tube normally sits) to prevent deformation.
For now, the product has convinced me, and I plan to buy two more pieces for my MTB.
