• Just started riding a bike I haven’t used in a few months, with 26x2.8 WTB Rangers, Caffelatex sealant.

    Topped up with 60ml of sealant, rode a while, started slowly losing pressure. Topped up a bit more, took wheel off and swilled it around… still slowly losing pressure. Only the rear, front is OK.

    No visible sealant peeking through anywhere.

    Bizarrely, I can’t hear or feel any sealant sloshing around inside the voluminous tyre, and there’s no sealant sputtering through the valve when inflating/removing the core. Even though there’s now around 150ml of fresh sealant in there…

    What to check next? Please don’t say remove the tyre, these are a bitch to get off the WTB rims…

    If your tyres/wheels don't hold air - pump them up and cover with a washing up liquid and water solution. Bubbles will form at the point of leaks, shake wheel around so sealant gets to the leak and hopefully it will seal.

    Clue is in the thread title
