My wife doesn’t drive, so I cannot use that - the only time I’ve been rescued, my mother-in-law picked me up…and that was only because she was coming to ours for lunch and I was just 20km from home on my way back.
Just read this, which seems good, never knew the thing about using CO2:
The Trainerroad guys rave about a combo plug tool, that is also a co2 inflator, and inflates through the hole you are plugging. Afraid I can’t be more specific than that, but Jonathan has mentioned about half a dozen different times on the podcast and is a big fan
CO2 turns your sealant to water and should only be used to reseat an entire unseated, totally flat tyre.
You then pump up the pressure with a hand pump.
You should NOT remove the tyre at the roadside. EVER.
If the gash/hole is large, use a “gummy worm”, then top up with sealant and inflate.
(what @r0bh calls the anchovies, which is a better name!)
So I ordered one of these:
and some of this:
I will be going NO SPARE TUBE, as that’s pretty much what I do with my tubulars, anyhow (I only take a can of sealant on rides of less than 2 hrs)
Hopefully, I can get that and my parktool IB2 into my Leyzne M caddy sack, thus fulfilling Rule #31
The problem is that the sealant glues the tyre bead to the rim of the wheel and is a PITA to remove. If I was to try and remove roadside then heavy duty leavers are required such as the Pedros.
I have decided to stick with tubes for riding and tubeless for racing.
I suppose I should expand my answer, as my long course days are over so for me racing are either TTs or duathlons so it would be a DNF. I have had two instances of punctures whilst racing, on a 25 TT and a sprint tri. The only way I knew I had punctured was the orange sealant up my back. I tend to add 60/70ml of sealant to my wheels as it gives me some comfort that if that doesn’t fix it then nothing else would.
