Still staggers me how resilient to punctures the modern tyres available for bikes can be. .
Indeed they are... I've only so far had punctures in OE (very thin) tyres and touch-wood my replacements that incorporate a kevlar anti-puncture layer have been immune.
Yesterday though it was a Conti Gatorskin - my favourite and very puncture-resistant - that appeared to let the unfortunate rider down... It was not the tyre or any impaling object but rather a failed tube. I found a little weakness on a moulded seam and it had gone there...
It fixed OK with a patch and I hope it got her home but I'd chuck that tube ASAP. Again, I only use good, quality tubes such as Contis... Although, having said that, the cheap BTwin tubes from Decathlon seem OK...

Why do you need Co2 cartridges Jim ? .......... you eat flap-jacks !

CO2 cartridges (just like the ones used in Sodastream machines) and a purpose-designed head is a great way of inflating a bike tyre without the need to carry a pump Alasdair... The only snag is the little cartridges get dangerously icy-cold in use so I carry a little insulating sleeve to slip over them...
If I ate a lot of beans before a ride I may not need to carry CO2 cartridges perhaps
