Off topic, but curious what you carry for when/if you need to put some pressure back in?

Hand mini pump (Topeak Micro Rocket Carbon), mounted underneath seat tube bottle cage.
For plugging holes: Dynaplug Carbon Racer with its two plugs + 3 extra tips (two small, one big).
And if this fails to fix the tubeless setup in a road-side repair, then I put a tube inside.
For this I carry a light Tubolito S-Tubo Road.
Don't forget to remove the plugs before inflating tube, otherwise it will say "goodbye".

I've carried CO2 cartridges + CO2 head in the past, but find the cartridges heavy (esp. if you carry two 16g cartridges).
Also if you mess up/ miss the shots, you are out of gas.
Mini pump I find more reliable, but it does not give you high volume in short time, which might be required to get tubeless tire seated again. But I don't think a 16g cartridge delivers enough oomph for that.

If your rim and tire make a good connection along the interface, then the tire beads should stay on, even if the tire is completely flat.
The dried sealant along the beads helps here, acting like a glue.

Dynaplugs are nice but uber expensive
The plugs cost about the same as a gel, but you'll only use a handful a year, if that. The ultralight carbon tool costs about £20. How is that uber expensive in a world where £5k bikes and £60 tyres is the norm? I'll gladly pay a small premium for something that actually works.
What's a gel?

Who cares if refills cost a little extra when they work better than anything else and save your ride without having to insert a tube? 5 soft-point plugs cost $10 on BikeTiresDirect. Besides my experiment with the Pro One TTs where I used three of them on a pair of tires, I haven't needed to use one all year. It's a wonderful safety net though, and the Racer Pro fits in my nylon canvas ride wallet.

Worms/bacon will slowly migrate out of a puncture unless you ride with your tire at low pressures for several days, allowing the sealant to cure/coagulate around the plug. Stan's Darts? They literally don't work on small punctures. When you stab the tire with the barb the rubber plug slides off the barb and never gets inserted into the puncture.
Bacon strips are pretty long. If you shove most of its length in the puncture, I would think it would be pretty unlikely that the whole strip will migrate out. But, I've only used a bacon strip once and it only migrated out about 1/8". I've seen it reported that the metal tip of a Dynaplug can pop off and rattle around in the tire.

Not the OP, but I read that as an energy gel.

I've had great success with just using small lengths of cotton butcher's cord inserted with the Genuine Innovations "fork" tool. The key to having them stay put is performing a ~quarter-turn twist of the tool prior to removal. This forms a loop inside the tire that makes it more difficult to work it's way out and even eventually becomes a "mushroom head" after sealant coagulates on it. Never had one of these come out in hundreds to thousands of miles of riding on them. No need to "ride at low pressures for several days". They've basically been permanent repairs on tires for me. Much less expensive than Dyna Plug and very easy to use since the cotton cord can be pre-loaded in the tool and ready to go. BTW, the same "twist" technique should be used with the elastomer coated "strips of bacon" as well to prevent pull-out.

Huh. Thought he meant sealant.

Results are in from BRR, according to them basically the same performance as the old TL tyre and slightly worse puncture protection.

Jarno found it much easier to fit which is a big win though.

How disappointing. So only benefits are lowee weight and easier mounting but RR is not improved and puncture protection for the tread is worse.
I wonder why all the pros used it, if its just a lighter GP5K TL.

Yeah. I'm tempted to go for the Veloflex Corsa Race's next spring. According to BRR slightly more RR but less weight and much better puncture protection.

Also having ridden Veloflex tyres before, the ride quality and grip will be better than GP5000's.

First ride this morning (had man flu).

Hated GP5000TL, always loved corespun casing tyres due to superior feel and grip.

Think these shall be my go to tyre. 700x28 come out at 29.2mm on 21ID Rovals. 275g on the nose.

Ran 72R/62.5F. Very comfy, not like riding on hose pipes. Felt spritely and rolled beautifully.

They shall be staying on my SL7 until the tan model arrives ;)

Interesting. I know that you have good experience of Veloflex tyres, how would you compare the 5000 TR's and the Corsa Race's?

I agree with this assessment of GP5000 vs Veloflex Corsa. The Corsa is lighter, has more puncture protection and will be more comfortable, with a small hit to RR and I assume tread wear longevity.

I am seriously considering the Corsa as my next tyre, but don't understand how it can be lighter than the GP5000 and yet have more puncture protection. Surely there must be another disadvantage?

Yes, bit disappointing. Did they beef up the sidewalls because they know that that is an area that struggles to seal with tubeless?

I suppose if it is lighter, not slower but rides better and is easier to fit to a broader range of wheels that is still a massive win.

I have to say I was hoping for a Watt or more of improvement.
