Quote from: chrisbainbridge on 13 November, 2018, 09:18:34 pmTo get back on track. I was seduced by the claims of finish line Kevlar sealant. I put it into two new tyres on rims that were designed for tubeless. The rear tyre has stayed up but the front has deflated on 5 successive days despite in excess of 100km and multiple re inflations to 100psi. I will be using stans in future.Had the same experiance. On paper it sounds like it should be great but in practice the liquid bit just doesnt seem to want to "cure" properly and make the seal. Maybe they had to make it thinner to carry the carbon fibre without turning to porridge, I don't know. Whatever it is, it doesnt work.

i haven't had this problem yet, but it can happen:https://www.youtube.com/watch?v=KYBM-WCAcsE
Good bits from the video was showing how easy it was to remove the tyre with his hands.
Specific question (probably for mike) what size valves do I need? I have Kinlin XR22Ts. Should it be depth (~22mm) + a couple cm? (I'm guessing 55mm would do as that gives me enough space for pump and knuts to hold it in place).
Better to do this at home, at your convenience, in the warm and dry...

Whatever it is, it doesnt work.My initial experience was similar, with lots of leakage around the bead and overnight deflation, but once I'd gone out for a couple of 25mile + rides it all sealed up nicely, and retains pressure as well as the tyres I've used Doc Blue on.I've yet to have a puncture tho, so have no idea of the level of performance there. I may top up that pair of tyres to make up for the initial losses.
Has anyone tried flying with tubeless tyres? Any issues to be be aware of?

Left to their own devices (ie in the shed untouched) the tyres with Finish Line in continue to deflate, one at an almost acceptable rate, the other most definitely not, with leakage around the rim as evidenced by escaping moisture. It might be a tyre bead issue, as the rims were previously used successfully with a different tyre.Anyway, after some thought, I've decided to revert to latex (or in my case pseudo latex Caffelatex) sealant. And I'm switching tyres to Fusion 5 All Seasons.
