The new Flat-less tire.

After 10 years, we have thoroughly overhauled the Marathon Plus. The only true flat-less tire gets a new, dynamic profile and boasts many internal improvements:

Features

  • Rolling resistance. The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. We further extended its lead in the latest version.
  • Recycling. Also in the SmartGuard, we now use a proportion of recycled rubber from old latex products.
  • „Anti-aging“ side wall. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.
  • E-Bike ready. The main sizes are approved and tested for E-bikes up to 50 km/h. Following sizes carry the ECE-R75 mark: 47-406, 47-559, 37-622, 40-622, 47-622.

What should you look out for with faster E-bikes?
Special tires are necessary for fast E-bikes. The best solution is tires with ECE-R75 certification, valid throughout Europe.

All our Energizer tires bear the mark and are valid on vehicles up to 50 km/h.

Product features
Under the tread is a 5 mm thick layer of synthetic rubber.
The tire has a classic construction with a wire bead and 67 TPI braid.

Values ​​occurring with shells
PSI - indicates the pressure to which the manufacturer recommends inflating the tire. 1 atmosphere = 14.7 PSI
TPI (EPI) - the density of the tire's skeleton fibres. The higher the TPI value, the more flexible the tire will be.
Kevlar shell - foot made of Kevlar fibres. The tire can be folded, so it is more practical when moving or storing. It is characterized by a lower weight compared to wire casings and a higher resistance to puncture.
Wire tire- bead made of wire. The shell is inflexible, it is heavier than Kevlar.

SK Plášť je fajn. Ochrana proti defektom dáva pocit istoty a oproti iným tohto rozmeru nemá výrazne vyššiu hmotnosť a ide dobre po asfalte aj šutolíne. Pozor na priľnavosť za mokra. Je to pre ľudí, ktorí majú radi trvanlivé veci

SK + za cely cas pouzivania plastov (~4 roky) som nemal jediny defekt prepichnutim;
- bocne steny by mohli byt este pevnejsie: mam 85kg a pouzivam ich na 20" skladacom bicykli, so sedlom posunutym dost dozadu, kde bocne steny zadneho plasta zvyknu pri skakani z obrubnika/na obrubnik povolit a vtedy sa zacnu robit velmi caste a otravne pinch-flat defekty na bocnej strane duse, a to napriek fukaniu na max;
+ tento plast ma na prednom kolese najazdenych ~10000km a dezen stale drzi;
- reflexny pasik je len pekna dekoracia - funguje totiz iba do prvej jazdy mestom pocas dazda, kedy sa zanesie mastnym sajrajtom;

spravne parametre:
tlak: 3.5-5bar/50-70psi
max. zatazenie: 80kg
