[#9986345]

Went out on Sat morning. Had a WTB trail boss fitted Tubeless onto some WTB i23's. All been fine. When i was out on a tech climb i noticed it feeling yukky... it was flat as a pancake.

As i'd only gone locally i didn't have any repair kit with me, so it was a hike for about 2 miles and get Mrs Weeksy out to rescue me.. I'd have got home in another 30 mins or so anyway.

First Tubeless failure in 2 years.

Weird thing is, i can't find out why... I re-inflated it and it's been fine since.

Only thought is that i didn't pop the bead on comepltelyย  when installing it a few weeks ago ? So it was holding pressure in the garage but lost it when pushed on ? I was a good 85 mins or so into the ride at the time of flatting.. It felt fine before that ....

I didn't get any puncture noise/explosion before it died..

What's happened ?

Are you running sealant?ย  It will seal many tiny punctures and you will never know...you don't always get sprayed with gunk.

Yep, Stans. Couldn't see any leakage etc when looking over it... I'd have thought if it had punctured and not sealed i'd see some evidence of it.

As above, i suspect the sealant just didn't quite seal when riding. I sometimes have to stop, and spin the wheel manually so the hole is at the bottom and the selant pools over the hole at the bottom.ย

I had the same a few years ago. ย Walked home (about 5 miles) as got so confident in tubeless I didn't;t take any repair kit. ย  Pumped up when got hime and went straight up and stayed up.

I now make sure I take a mini-pump/CO2 inflator in case that happens again.

Had same issue. Running low pressure, assume tire burped a lot of air then re-sealed once the sealant was sloshed around on the walk home?

Had you pump/check pressure before the ride ? ย If you pumped it perhaps the valve core was a bit gunked up

Sounds like a normal puncture incident to me too. Small enough hole to let the air out, but not visible once Stans did it's job. Went down when climbing probably because the wheel wasn't spinning fast enough to get the sealant in (centrifugal force an all that).

As mentioned,ย  spin and pump, pump and spin. ๐Ÿ™‚

May have worked if i had the pump... and or if by the time i'd ridden it 3 miles when flat it hadn't been completely off the bead..

Fair enough, lesson learned, will take the little seat pack again now ๐Ÿ™‚
