Tyre sealants

[ron b]

Had a puncture today while warming up, bit of a walk till I was picked and delivered back to HQ. I use Tubs on my TT bike, supposed to save an hour over a 25 TT. Question is has anyone tried a “sealant” to mend a puncture? Any info would be welcome.

For Tubs I would suggest Effetto Mariposa Espresso for an emergency solution;

And for Tubeless I would recommend Effetto Mariposa Caffelatex or Orange Endurance as they seem to seal at higher pressures compared to other brands;

The Effetto Mariposa Vitamina CL sealant additive looks good but I've yet to try it although installation looks to be a bit of a pain;

You could put sealant in your tubs however;
1. It will harden latex tubes over time
2. It needs to be replenished every couple of months

Thanks Jason, I am looking for a permanent  fix and because it’s a rear wheel capable of holding a high pressure. The wheels are not used too often so is it worth the money or buy a new Tub?

A 60ml pack for under £5 might be worth a shot but it depends on how big the cut is;

If you do go for it only inflate to a low pressure, maybe 40psi or so as it might give it a better chance at sealing - If it's held overnight then inflate to a higher pressure.

Once you've injected the solution make sure that the puncture is at the bottom of the wheel, as it sits/stands on the floor, this will allow the sealant to head straight for the hole.

Just used “Stans” the jury’s out!

[Jason T]

I never had much luck with Stans sealing at higher pressure, I think it's more suited to lower/mtb pressures but hopefully it will work for you.

How's the tyre looking Ron?

I use stans on the TT bike. On a club 10 I heard the sound of a puncture (big hiss) 3 times but tyre looked OK so carried on. At the end of the TT was talking to the others and mentioned it but could not see any evidence of a puncture. It was only when i noticed the hairs on my leg were matted from the knee down and closer inspection of the front tyre it was obvious i had had a front puncture. Changed the tub and and all good. So stans did work for me as i finished the race,I have Tuffo tyres and they run at 175PSI

It’s still holding 100, didn’t use it yesterday, I will put it on my hack bike and ride around locally. I will increase the pressure after that. Thanks for all the info, in the olden days I would have undone the stitching and repaired the tube and stitched it back up again, they were never as new though. I will probably replace it for next year.
