I'm a late adopter and decided to go tubeless with my 29er On one reet'ard wheels.
Looked easy so cleaned the rims with IPA, gorilla tape, valve, spec Purg tyre, couple big glugs of stans (100ml ish) soapy water and ghetto fire extinguisher seated it, it worked!
Pumped up to 40psi, bounced it about and rolled/spun/jiggled.
Checked it nightly for about a week like an expectant father and all good. Two weeks later and flat!
Any ideas what I might have missed or the issue? Did struggle getting the valve to seat in the rim recess so had to use a little o-ring.
Thanks in advance for help and humiliation
Ps it's not a used tyre but doesn't have any cuts
It can take a few rides to seal completely - or at least that's what I found on a similar setup.
Both sets I have got do need pumping up occasionally, but as the bikes are in the house it's pretty convenient to do!

Thanks Si, I was half tempted to chuck a little more stans goo in and try again.
Yup do that.
Some soapy water round the tyre will show if there's any swift leak. Just pump it up and go for a ride.
If it's a very slow puncture that doesn't interfere with riding then it should fix itself after a ride or two, that's my experience anyway.

I'll bet, it's the "Purg" tyre. I had the same thing with a brand new set up - UST rim, Purgatory 2bliss tyre, plenty of sealant, satisfying pop of a fully seated tyre....flat over night, regardless of what I did. Ended up sinking it in a tub of water and you could see little air bubbles seeping out of the side wall. - all over the side wall, not just a small nick or slow puncture, btw - and yes, I brushed the bubbles off and they reformed.
I gave up running Specialized tyres years ago when the sidewalls seemed to split if you pointed them in a direction of a stone. Tried this new 2bliss one thinking, "they must have sorted their crap tyres out by now..." How wrong I was.
In comparison, the same set up with a Hans Damf, Geax Gato or Maxxis Ardent works perfectly and rarely needs topping up with air.
I'm a late adopter too.. And have suffered a similar experience to yours. Flat tyres after one ride. After all this faff, prepping rims, tyres, inflating, bouncing, checking, inflating again, etc... I really can't work out what the actual cost benefit value of this tubeless faff really is. An inner tube cost £3 and goes inside a tyre. You pump it up and ride.
I may be reverting back shortly.
Add extra goo, do the tubeless"shake&bake" dance and repeat.
1. are those wheels TLR?
2. How well did you tape them.
3. Did both beads "crack" when you inflated them? Beads sometimes need 50+ psi to seat properly.
have you had any 'punctures' yet no eyed? tubeless is brilliant when you say ride over a thorn. You hear the hissing, put the hole to the bottom and wait for the sealant to seal the hole, maybe put a bit more air in then off you go Vs bike down and the 30 mins of faff to change an innertube while your mates are waiting.
Thanks for all of the advice guys.

No, don't think the wheels are designed as TLR
Took my time to take and press down, rim cleaned with IPA first
Yes, bead well located when I inflated.
Thanks
Think i'll go down the more Stan's goo and see how it goes.
?? How much Stan's sealant so people use for a 29er tyre 2.2-2.4?
Cheers
According to Stans, its a good idea to put a tube in 1st time and inflate and leave for 24 hours. This ensures that the tape is firmly seated. Also handy as when you take the tube out, 1 side of the tyre bead is now seated.
However, 1st thing I'd do is find out where the leak is. Soapy water and a sponge all round and leave resting horizontally for 15 mins, followed by the other side will quickly identify any leaks.

It can be a bit of a bind when it doesn't work straight away. But anyway it moves the faff to before the ride rather than during it.
It's worth it for me as I was puncturing every single ride, and it was giving me excuses to be a lazy blob 😛
The Specialized 2bliss tyres are quite good IME, but they are more like "Tubeless Ready" than a proper UST tyre, so your first lot of sealant will mostly end up sealing those porous walls....
That and actually riding the things, the "Stans shake" helps, but riding them lots helps things settle in and distributes the sealant where it needs to go...
assuming you have a removable valve core, I'd put another "Glug" of sealant in, inflate it to your preferred riding pressure and go for a nice long ride or two...
losing pressure over a week or two isn't unusual, I tend to top up my tubeless tyres frequently, twice weekly or before pretty much any long ride just to be sure...
