• Yes, I guess weight is similar once you have accounted for sealant, and unlikely to be a primary reason for switching to tubeless.

    Consider the Schwalbe 'Pro' range:

    • For a 28c tubeless (i.e. Pro One) it's 2 x 275g = 550g
    • For a 28c 'normal' + tubes (i.e. Pro) it's 2 x (245g + 105g) = 700g

    I imagine that sealant would use up some of that 150g difference.

  • Yeah, good point on the valve. I thought about that after I had posted. 10g each?

    So, for a 28c tubeless (i.e. Pro One) it's about 2 x (275g + 50g + 10g) = 670g
