Best internal patch for tubeless MTB tyres ?
I am about to swap my nearly new Continental XC tyres to some new rims. I know that they have three punctures, two of which I repaired quickly with temporary plugs. What's the best internal patch or permanent internal mushroom plug to use to replace the temporary plugs? I have some car ones but they are a bit too thick and heavy so presume that there must be a dedicated quality internal tubeless MTB patch or plug that people use ?
