• First foray into tubeless, I've got tubeless rims which came set up with Gorilla tape. I've got GravelKings (the non tubeless ones) which appeared to seat themselves with a track pump yesterday, but didn't hold air for more than about 2mins. No sealant in there yet. Is that all sounding right so far?

    Am I right in thinking, if it looks like it's seated, I can glug some sealant in there and pump it up, swish it around, and all should be ok?

  • my (GK non tubeless ones) stayed up with some Stans sealant in and have been fine for last 1000miles - mine are on Pacenti rims though. I would put 50ml ish into one and see

  • If the beads went on with a crack then it sounds good. I've got a set of road wheels with a single wrap of Gorilla tape.

    I put on a set of 650×38 GK at the weekend and one went up and sealed almost perfectly straight away. The other one wasn't so well behaved and after finding the big rim leak, it took a while to find and seal a small sidewall leak at 50psi.

    Use a washing up liquid solution to find the biggest leaks first, then work on minor leaks or go and ride them.
