Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Just the juggle to get the valve core back in can be a bit stressful...

Have you considered dexterity training?

That would be tricky. Apart from anything else, it's safely locked away in it's own little house in the garden and hardwired (electrics and air hose) into place. It also weighs more than I do.

This whole thing could be fun if there was any tyres.

any advice on removing sealant from clothing?

Wash it?

"sealant", you say...

obviously tried that already...

Gotta say... Making a homemade pop bottle airshot was one of the most satisfying things ever. Just that feeling of seeing the tyre pop straight onto the rim at a cost of zero pence, with no furious track pumping.... Never shall I piss about with a stubborn tubeless tyre again! :)

Had my first tubeless fail last week. Unlocked bike after work, thought the tire looked a bit soft so stuck more air in (not flat enough to have popped off the bead). Got about 10 min down the road and it had gone flat enough again that I almost rolled it in a corner.

No obvious signs of cuts, or pissing out latex so I assumed the sealant must have dried up, but when I popped the tire off it still had about 45 ml of liquid sealant in it (so even if it was no longer sealing a hole it would have been spitting out?).

Any idea what could have caused it to lose air like this? Tire had previously been holding pressure for ~1 year.

Try to find where the air is escaping.

I couldn't hear anything leaking out either time, and the amount of liquid latex still in there should have spurted out somewhere?

At the point I stopped the second time, I just bunged a tube in and rode home

Often shaking sealant towards the leak can get it to seal.

Best bet is the valve moved and unsealed with the pumping

Mavic launching UST road, finally.

Anyone used those little 'anchovies' to repair their tubeless tyres? They seem popular for big tyres, but not sure how they'd hold up for 28-35mm?

Just installed 28mm Pro-ones on DT Swiss R460 db, using DT's valve and tape, seeing as they test their stuff together thought it would be a fairly safe bet.

First tyre I inflated with an inner tube first to get it seated, then removed innertube and re-inflated. Second one I didn't bother putting the tube in first. Both inflated and held air without sealant, using my home-made 1.5l soda bottle inflator at 50psi.

Put 15ml of sealant in each, although reading around, that seems a bit low according to recommendations, so I'll ride them around a bit, check for trueness in my wheels, and maybe add a bit more sealant.

All in all, fairly painless, apart from trying to get the tyre on with a tube in. Had to resort to the levers for that. Fingers crossed they hold air overnight!

Have you covered them in soapy water to identify any places air may be escaping?

I put some on to get them seated, but leaving my track pump connected after inflating, they didn't seem to be dropping. A bit of sealant squeezed out under the valve, but that was because I hadn't re-tightened it after getting some air in there.

It's much quicker to cover the wheel in soapy water and see if any bubbles occur than to wait overnight to see if the tyre has lost pressure!

In my experience you add 30ml of sealant after 3 weeks. especially after you put only 15ml in the first time.

Just been for a quick nip to the PO. Back tyre is losing pressure, I'll address that tomorrow when I have time! Thanks for the soapy water tip. I'll stick some more sealant in at the same time. Annoyingly, Dt valves don't have removable cores so I'll have to pop one of the beads again.

You can push sealant past the valves. Removable cores are just cleaner and help with seating the bead as the initial air dump can get in quicker.

I guess as long as I'm sticking air through it afterwards, it should clear it out eh?

As suspected, air is escaping from the rim joint as it's sleeved on the R460. Any pro-tips for sealing it? no amount of shaking and jiggling seems to get sealant to plug it.

It's meant to be tubeless compatible. Cover the outside with soapy water. There is a circular shaking motion you can make to try to get sealant into the place where air is escaping. If this doesn't work you could try putting in more rim tape to cover the join.
