Trying to set up a set of arch ex rims with 25mm Stans tape, and tubeless valves using proper UST tyres. Kind of amazed how hodge podge the whole system seems to be; quite precarious? The way the valve just drops into the rim tape without any real seal, beyond a rubber bung seems quite strange.
I also cleaned out the tape from where the bead of the tyre is meant to snap into the rim…cutting off about 1mm around the whole circumference of the rim, because the tape seemed to be on the verge of being too wide. I don’t think this is what has caused my problems.
I’m using single wrap of the tape round the rim and even with some liquid latex am struggling for it to hold air. I get leaks around the valve itself, and some around the tyre (they dribble and spit latex for a few hours…)…but the tire loses probably half its pressure in 24 hours.
I think I was happier with my ghetto tubeless, old 20inch inner tube set up!!! Makes much more sense!?
Any hints?
