A CO2 cartridge works but this one is better. I have some rims that are almost impossible to mount and seat. Others I can mount with my hand but I have never been able to seat the bead with my hand pump. Rather than buying a special pump, I decided get a compressor. Since the new continental tubeless leak so much, airing up every two days is very quick.
