• 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.

  • Stans produces Schwalbe Doc Blue Professional.

    This page says

    Dose: 60 ml/tyre (Race bike 30 ml)

    So how dense is sealant?

  • sealant is about 100 grams for road tires

    Try using a bit less 🙂
    I weighed my 25C Pro One installation complete with double tape, valves and a generous portion of sealant and it still only came to 80g for the pair over the raw tyre weight.
