Fix a Tire in Nothing Flat
Even the best mini pumps take forever, but in an instant a CO2 cylinder can deliver more than enough air to get you home. A 16g CO2 cartridge will put about 40 psi in a mountain bike tyre and about 125 psi in a standard road tyre. And they're small - about one-sixth the size of a frame pump.
TIP: Consider practicing using cartridges a couple of times before you road test your new system; using CO2 cartridges can be a little tricky at first.
Avoiding Pinch Flats
Putting too much air into a tube without making sure it's seated properly in the tire can cause a part of the tube to get pressed against the edge of the tyre. When the air pressure reaches near maximum, that pressure on the tube can actually cause the tyre to cut the tube's rubber, resulting in a "pinch flat." That's why you should put in about 20 pounds of air and then "massage" the tyre (to help seat the tube in the tyre and the tyre on the rim) before you fill it to the brim.
CO2 refills are not always easy to control, even when the adapter can turn the air on and off, so it's a good idea to keep your pump with you. Use the pump for the first push of air, massage the tyre, and top the tube off with the cartridge.
- Great servcie Review by Dave Graham
I've recently started using CO2 cartridges on both my MTB & road bike - I won't be going back.
Thanks Velogear for stocking them at a competitive price, and delivering them so quickly.
