Overview

Tubeless riders on any kind of bike who want a long-lasting sealant that copes with bigger holes.

Tru-Tension Tubeless Sealant is blended with carbon fibre and graphene to build a stronger plug around a puncture, so the fix is more likely to last. It seals holes and tears up to 7 mm and also seals porous rims, tyres and small gaps during setup.

It's ammonia-free, CO2 compatible and designed not to gum up or ball, with Tru-Tension quoting up to 6+ months in the tyre. Suitable for MTB, gravel, road and track.

The 500 ml bottle covers a few tyres: roughly 30 to 50 ml for a road tyre and 80 to 100 ml for a 27.5 inch trail tyre.

Seals up to 7 mm

Carbon fibre and graphene build a strong plug.

Long life

Up to 6+ months in the tyre.

Ammonia-free

No ammonia in the formula.

CO2 compatible

500 ml

Technology

Carbon fibre and graphene

Particles blended into the sealant to build a stronger plug in the puncture for a more permanent fix.

Who it's for

Great for

  • Setting up tubeless tyres
  • Topping up existing tubeless setups
  • MTB, gravel, road and track

Maybe not for

  • Tyres with inner tubes (Tru-Tension makes a separate inner tube sealant)
  • Punctures bigger than 7 mm, which need a plug

Minimum per tyre: road 30 to 50 ml, 26" MTB 60 to 80 ml, 27.5" MTB/XC 80 to 100 ml, 29" MTB 105 to 140 ml, downhill 120 to 140 ml.

Worth knowing

Top up before it dries

Sealant slowly dries inside the tyre. Check it every few months, and before a big ride or race, by giving the wheel a shake and listening for slosh.

Shake well

Carbon and graphene particles settle in the bottle, so shake it hard before pouring or injecting.
