Our 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.


TCS Rims

TCS rims combine the best of everything – UST compliant rim bead shapes are designed to help keep tires on rims better, while a tape and sealant system shaves away critical weight. Build them up with your favorite hub and spokes for a dream wheel set that's easily serviceable at any bike shop.

TCS Tires

TCS tires boast the ride benefits of a tubeless tire with the reduced weight of a non-UST tire. TCS tires combine WTB's lightweight race casing with a sealant tubeless, UST compliant bead. Those seeking extra durability can go with our TCS Tough tires for thicker casings.

TCS Sealant

We tested every sealant on the market and found WTB TCS Sealant to be the very best. It is race proven and rider recommended.

TCS Rim Tape

Light, strong, and extra sticky for durable, long-lasting, leak-resistant performance.

TCS Valve

New Taper Design allows for optimal fit on a wide variety of rims. Removable valve core for easy cleaning and uninterrupted inflation.


"It's hard to find ways to take weight off your bike while still adding performance and durability. TCS tire and wheel systems do just that without making your bike an anchor."
- Mark Weir


"After the staff at WTB helped me out and walked me through it, I can change a TCS tire quicker than I can change a tube."
- Bobby McMullen


"One year we took 30 media guys riding. Thirty flats later I swore I would never take anyone riding with tubes again. Last year, we set the same number of bikes up with TCS wheels and tires, and had only one flat. The difference is huge."
- Jason Moeschler
