Tubeless road - it actually works

Fingers crossed, haven't been stranded yet. I do always carry a spare tube though just in case. I can't say for sure if I've ever had a puncture that said though.

I found the whole process actually handy enough. The tyres went easily enough - bit of a wrestle onto the rims but not significantly worse than the Conti 4 Seasons I had been using (these are Vittoria Rubinos 28s on a DT Swiss rim). I didn't need anything other than the track pump to get them to seat, and they held air fairly well before adding sealant. For the sake of the few quid, the injector is worth it I think. I would just find the mess of having to get the tyre off the rim, adding sealant and trying to wrestle it back on an ordeal, whereas the syringe is super quick - top up took about 5 minutes.

They're not necessarily for everyone, and I'd say anything less than 28mm tyres, you're into diminishing returns, but I'm glad I did!

I got this one https://www.alltricks.com/F-11929-outillage/P-21610-notubes_syringe___injection_preventive_tips It screws onto the valve which is handy and has a little screw on cap to prevent residual goop leaking and making a mess

A tube actually.

Tyre plugs, to deal with any punctures that the sealant won't fix

If the hole in the tyre is too big to be plugged, you'll need to fit a tube as dahat has mentioned. Just make sure you can undo the locknut to remove the tubeless valve stem.

If you do get to the "fit a tube" stage, check the inside of the tyre - not just for whatever has caused your current puncture but for also other thorns or bits of glass which punctured the tyre in the past but sealed.

(Unplanned 🙄) new wheelset on the way which is tubeless ready, so plan to go tubeless with them. I'm fed up fighting tubed conti's onto rims so not inclined with tubeless, what's the equivalent/ better option to the 5000? Pro One/ Pro Zero/ Corsa N.ext? Probably only racing them for the moment (will keep the stock wheelset for days out).

Looking around it may be a case of whatever I can get in 28mm! Also decided to go for the airliner inserts - as I'm going tubeless, may as well have the ability to limp home rather than cover myself in sealant!

Mucoff make an inner tube sealant, no idea if it’s any use. I’d say regular sealant is probably useless as won’t react with the butyl.

Here is an unusual tubeless tyre failure I experienced recently. It's a Bontrager GR1 tubeless gravel tyre. Half way through a spin after a fast section (50KM) the rear wheel felt like I was running over a pothole every revolution. Stopped to investigate and noticed a bulge in the tyre. There seemed to be no loss in tyre pressure, it had been inflated a few days previously to 40 PSI. Was able to cycle home.

It was obvious the tyre needed to be replaced, new tyre cost nearly €60 + 4 oz (120ML) bottle sealant @ €8

When I removed it, the inner lining of the tyre (circled below) was damaged in a circular patter., I can only speculate I may have hit a bump in the road to cause an impact for it disintegrate like that.

Removing and changing the tyre was easy, requires a little effort to break the tyre seal with the wheel rim. Inflated with a track pump to ensure it sealed on the rim. Don't forget to check the direction arrow marked on the tyre sidewall before you fit the new tyre. You should hear a few audible pops when the type fits in place.

I did not have a valve core tool, I unscrewed it using with a miniature spanner set I had available,then added the sealant. (how much sealant needed - There may be guidelines on the bottle).

Pumped up the tyres and left it for a two hours, no pressure lost and test ride ok.

tubeless let me down today. Tyre had only been resealed on Friday and then whoosh. Strangely happened on newly resurfaced bit of road

Of course, I hadn't bothered to bring a spare tube (first puncture in 9 months), or pump, or the phone

At the moment I'm adding it quite regularly. As I'd tried a few brands of sealant, I think I need to go and remove all sealant now. to save weight at least!

I'm using stans sealant on 38c tyres @50 psi.. but think its too thin. anyone got recommendations for sealant? one of the lads in bike shop recommended muc off but Id tried that also and wasnt too impressed.

yeah I'm running 40psi front 50 rear. To be honest I will give the stans a bit longer.. I have tried a few brands now and probably part of the issue is that they will have mixed. Need to fully clean out the tyres.

Yeah I read a few reviews there after and stans race seems to be able to fill larger gaps.

I had been wondering if filling through the valve core is preventing some of the larger particles from getting into the tyre.

this thread revival was timely, as after the morning school run the back tyre was down again. It had not yet had much stans in it.

So I took the tyre off and cleaned the previous sealant off. It did not look to be in a good state. nutrak by oko - do not buy this.

Added probably 80ml stans, shook it well. A few holes seem to have re opened and a disappointing amount of sealant left during inflation.

Going to check now and see.

None of the holes in the tyre are particularly large, id say 2 or 3mm. a tubeless repair dart is too big for em.

I've found it works well, if you trust it for the whole process when putting on the tyre (i.e. do not just use it for the last tight bit, but the whole way around).

Bear in mind that those will not work with hookless rims, such as those used on the Giant SLR carbon wheelsets.

Tubes anyone??
