WTB produces some of the best tires you can ride, so it stands to reason that they developed a top quality sealant to go along with them. TCS Fluid employs nano-capsulation to form a liquid that hardens upon puncture, creating a permanent plug that remains flexible and rubber like. Unlike other sealants, TCS Fluid does not change tires’ rubber properties and comes with an applicator for removable core valves.

WTB's TCS (Tubeless Compatible System) technology is the solution for riders seeking high performance, lightweight and durable mountain bike wheel systems that are easy to install, fun to ride and simple to service. TCS tires are the first sealant tubeless tires to receive Mavic UST certification, which means a proven fit between sealant tubeless tire and rim. Say goodbye to air compressors, tire levers and pinch flats. Say hello to your full riding potential.


  • The narrow bottle with flexible hose allows for easy installation through a TCS valve
  • A latex, nano-capsuled formula remains as a liquid in your wheel then immediately clots and plugs when a puncture occurs. The permanent plug is flexible and rubber like and does not negatively affect your ride
  • The TCS formula does not change the characteristics of the rubber in a tire
  • Recommended minimum usage: 2 fl.oz or 60ml for 1.9-2.0 26" size tires. Larger diameter and air volume tries require additional fluid
