• Super easy.

    It shouldn't be this easy, but then you did have a non-tubeless ready tyres, my experience is only on tubeless tyres and it should always have a tight to near impossible fit (pray it's not the latter).

    Sound like you answer your own question TBH; replace valve.

  • Yeah, my former experience of Schwalbe's (Pro One TR, Marathon non-TR) has always been painful, as you suggest, so it was a pleasant surprise when it went on without too much of a fight. Just annoying the issue seems to be the valve. Hey ho!

  • Just annoying the issue seems to be the valve. Hey ho!

    I'd think that a bonus because it just means it's an easy problem to fix!

    Valve recommendation; Stans own, or Halo.

    I favour Halo simply because it's easy to undo the washer to be use to remove the valve core;
