I bought it as a spare inner tube because of its light weight. It fits better in my pocket than the thick-walled inner tubes. It hasn't been installed yet, so I don't know how reliable it is.

I also had a different box than the one in the photo but the weight is almost the same, I guess I have the wrong weight the box doesn't bother me, the admin probably doesn't have time to change the photo

The hem strap seems unnecessary to me, but that's MAxxis policy...
Reliability, whether in terms of maintaining pressure or against a puncture, is determined by the wall thickness and, of course, the type of plastic and its protection against a puncture.
I see it as an alternative to milk in terms of weight, and for regular road light plastics without good protection, I would recommend going for Ultralights (67g) or squirting a little milk directly inside.
It's easy, because all MAxxis tubes have Presta valves that can be manufactured.

Maxxis are the best inner tubes. I use these in tubeless.

Be careful when putting it on - thin rubber

The delivered inner tube does not correspond to reality. The weight is 58 g, which is quite a big difference compared to the declared weight of 50 g, stated on the packaging! I even received the product in a different box than the illustrative photo? And in your seller description you state 52 g (37 mm valve). Where is the truth???

Good weight, but very poor puncture resistance. Two punctures on the inside after a few km, which has never happened to me with heavier/more durable tubes.

Unfortunately, it ended on the first pit (my mistake). Next time I'd rather go a little less ultralight

The declared weight on the packaging of 50 g does not correspond to reality, I weighed 59 g!

Defect on the second ride - around the valve, so that it couldn't even be repaired - 4 holes.

Product questions

SK Dobrý deň. Kúpil som si tieto duše najmä kvôli hmotnosti. Na dodanom obale výrobca udáva hmotnosť 50 g, ale v skutočnosti je až 58 g! To je obrovský rozdiel. To nie je seriózne jednanie a jedná sa o zavádzajúce údaje! Čo s tým mienite robiť? Napíšete výrobcovi, aby to uviedol na pravú mieru, alebo možno balí do obalu iný výrobok? To si môžem radšej kúpiť aj lacnejšiu dušu so zodpovedajúcou váhou!

SK Otazka je trochu tendencna: Na obale je bud 54 alebo 56gramov a to uz nie je taka odchylka hlavne pri takej hrubke steny duse aj ked si "gramar".
MTBiker s tym asi moc neurobi kedze ju muozes kupit aj inde ale za horsiu cenu .
Doporucoval by som Customer Care priamo u Maxxisu.
Pozri este moje nove hodnotenie ohladne pouzitia ... a nabuduce by som doporucoval
"trochu menej pary".
Nie som MTBikeru ale snad neporusujem pravidla odpovedi (kedze mi to tu technicky ide)

SK Vážený pán Husovsky. Nemáte vôbec pravdu a podľa toho, čo píšete, mi asi dodali iný výrobok. Pošlem Vám odfotenú originálnu krabičku (ak mi pošlete Vašu mailovú adresu), kde je údaj 50 g!!! Takže neviem, kto zavádza? A v takej gramáži som si mohol kúpiť aj o polovicu lacnejšiu dušu!

SK Vazeny pan Han. Ak sa bavime sa o 37mm ventile tak sme asi kazdy niekde inde. Ja som hovoril o 60mm. Pozriem este krabicky a dam do hodnotenia.
A celkom by zaujimal typ na tu dusu za polovicnu cenu ..
To mate aky rafik ?

SK Vážený pán Husovský. Hlavne sa zamerajte na výrobcov a obchodníkov, ktorý nás spotrebiteľov neustále klamú a zavádzajú. Je ich veľa a snažia sa predať svoj výrobok niekedy za každú cenu. Chudák spotrebiteľ sa môže orientovať podľa ceny, vlastností (tam patrí aj váha), sympatii k značke, alebo referenciám užívateľov, testom...Vy ste ma "zvozil", že som si vybral váhu a určitú cenu (výrobcu som neriešil). Dopadlo to tak, ako som popísal a výrobca (resp. predajca) stratili u mňa dôveru v ich serióznosť. Pre príklad, napr. firma TUFO ponúka plášte s garantovanou váhou a tak radšej vyrobia tento plášť s deklarovanou váhou radšej o niečo ľahší! Super! Sú seriózny, klient je spokojný, obchod nemá problémy a v budúcnosti nikto nemusí písať takéto články (vrátane Vás), aby dostal to, čo niekto deklaroval. A tá cena by mohla byť tiež polovičná, lebo okrem vyššej váhy tiež pribaľujú pásku do ráfika, ktorú takmer nikto nepotrebuje!

SK Vážený pán Husovský. Asi to nemáte dobre zrovnané v hlave! Nikdy som sa "nenavážal" do obchodu, ktorý aj ja využívam k mojej spokojnosti. Asi zle čítate, pretože som písal o výrobcovi a záleží mi na tom, aby obchod udával relevantné údaje, čo je v prospech zákazníkov a samozrejme aj obchodu! A ak nerozumiete, čo sú to technické parametre výrobku, tak prosím Vás radšej sa neozývajte, pretože pôsobíte ako diletrant!
