WTB TCS Tubeless Sealant

WTB TCS Tubeless Sealant is a sealant with WTB's own development and recipe, made from synthetic latex and ammonia-free, which can damage rims through corrosion. It is the best choice for quick and reliable repair of punctures up to 6 mm.

TCS Tubeless Tire Sealant uses a stickiness process to seal punctures, rather than relying on the evaporative effects of many ammonia-based recipes. As a result, the sealant works better in humid conditions where other sealants have problems coagulating due to reduced evaporation.

Note: The manufacturer recommends thoroughly mixing the sediment at the bottom of the bottle before applying the sealant.
Product features
The sealant does not contain ammonia, which damages the rims
It uses the process of stickiness to seal the defect, instead of evaporation, and thus works better even in humid environments
Synthetic latex keeps sealant fresh for many months of riding
Sealant works best at most common riding temperatures down to -9 °C

Variant WTB TCS bezdušový tmel, 473 ml

It is at a good price, similar to other latex milks, and the positive thing is that it is ammonia-free.
In time, it will become clear what it shows.

Variant WTB TCS 2.0 bezdušový tmel, 118 ml

Zdravím. Je gel aj s aplikátorom? Lebo moje prvé nalievanie gelu bolo peklo než som zistil že striekačkou na to určenou to nedám a že to musí byť originál. Ďakujem.

HU Netlačte pneumatiku úplne dovnútra, keď zostáva už len 15 cm, nalejte mlieko do spodnej časti, potom otočte koleso a zatlačte pneumatiku na miesto. Prepáčte, napísané pomocou Google Translate.

SK Mne to cez striedačku nešlo. A to som sktruekčku tú org.na to. Natiahnuť mlieko v pohode ale dnu ani za svet. Premýšľam ci to nebudem dopĺňať iným mliekom a potom to proste vymením po nejakej dobe.
