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…
