These threaded CO2 cartridges from Azur are perfect for riders who don't want to carry a larger hand pump or need something with a bit of extra oomph to help them seat stubborn tubeless tyres. (we recommend re-inflating the tyre with normal air after you've seated the bead to get the best life out of your sealant)
