@GoatandTricycle apparently CO2 is not the best as it can freeze the TPU or something more technical which I don’t know. I think it’s use a pump when using these as a spare.
Also, not recommended for rim brakes as they have a tendency to burst when the rim heats up with lots of descending/use. Not ideal!
@Pifko I brought from a UK eBay seller. The price was £14.50 as opposed to £12 and delivery should be here tomorrow so it was a no brainier.
@HoKe as others have mentioned TPU.
