This tube is made from TPU (Thermoplastic Polyurethane) instead of butyl rubber. It weighs roughly 70% less, packs down to a fraction of the size, and cuts tire blowout risk by about 40% compared to a standard rubber tube.

Yes. This tube uses a metal valve stem with a removable air valve core, so you can unscrew and swap just the core (compatible with CLIK-style cores, sold separately) instead of replacing the whole tube.

TPU tubes need a dedicated TPU repair patch kit — standard rubber patches won't bond properly. No special tools are needed beyond your usual tire levers and pump.

It has a metal Presta (FV) valve with a 45mm stem length, suitable for most standard MTB rim depths.

Yes, generally better. TPU has lower gas permeability than butyl rubber, so it tends to lose pressure more slowly between rides — you'll spend less time topping up before you head out.

Yes. TPU handles heat build-up from braking and long descents, and resists UV degradation, better than traditional butyl rubber — helping the tube stay reliable for longer.

Roughly 80% less bulk when folded compared to a standard rubber MTB tube, so it's easy to carry a spare in a jersey pocket or small saddle bag without eating into your storage space.

We don't recommend adding tubeless sealant to this tube — TPU isn't designed to interact with sealant chemicals the way a tubeless-ready tire is. Use it as a standard inner tube, and carry a dedicated TPU repair patch kit for on-trail fixes.
