Genuine Innovations G2628 Ultraflate Plus Tire Inflator

First, a bit of advice: always carry a bicycle tire pump in addition to your CO2 inflator. The CO2 inflator is really ideal for when hand pumping starts to get difficult as pressure builds in the tire, but not by itself. Your ride, your comfort, and your endurance will all be far better if you’re better equipped.

You will need the hand pump to start out the tube, and should use it to quickly do a pumping until it starts to get hard to move the pump, THEN use the CO2 inflator for the hard part. By using the hand pump first, you can inflate the tire fully using only one cartridge instead of two or three.

A road tire will pump up to 100 psi on one cartridge, one shot, on a warm day. On a cold day, below 40F, the cartridge pump could be almost useless. Know also that this pump is compatible with every kind of cartridge except 12 gram threadless, which are hard to find except for the air rifle cartridges that contain silicon. But they work best with 16 gram threadless, so you can use handle and all.

The locking switch is a great improvement over an old CO2 inflator, which didn’t have this feature, so that you can still use that bit of air that may be left in a partially used cartridge. You have to be careful with this type of inflator. You can easily over fill your tubes! This isn’t the product’s fault, it’s the user. Give it a quick one or two bursts with the trigger and check the pressure before you inflate it any more. This inflator will take both threaded and non-threaded CO2 cartridges. If you use threaded cartridges you do not need the lower portion of the inflator which means you can pack even lighter.

The Innovations Ultraflate Plus Tire Inflater is a great bicycle pump that has a durable build and fits most CO2 cartridges. It is easy to use with built in safety feature and trigger inflation. Works with ALL Genuine Innovations CO2 refill cartridges (except 45 gram).

The advantage of the Ultraflate Plus Tire Inflater is that it will accept either threaded or non-threaded CO2 cartridges. And that is a big advantage if you’re on a ride with some others and you realize you don’t have a full cartridge with you and everyone else has nothing but non-threaded cartridges with them. Works with Schrader valves as well as Presta, but you must be careful with road bikes because it takes less than one cartridge to fill up a 700cc tube. It’s lightweight and small, so it won’t take up much room in your bike tool bag. It comes with one 16 gram CO2 cartridge.

Replacements can also be obtained from most any local bike shop. Fortunately for those on a budget, the 12 gram CO2 cartridges that you can buy from the sporting goods department also work. The 16 gram CO2 cartridges can be a bit pricier, so you can save yourself some $$$ by buying the much less expensive 12 gram CO2 cartridges. If you don’t use up a full cartridge, there is a locking mechanism that prevents the release trigger from being depressed when stowed. This tool is highly suggested, if you don’t have a pump and are short on space (like most road bikes). This thing fits nicely inside a mini bag under the seat along with the multi tool and spare tube and patch kit. Works great and super easy. This product is a super handy novelty, which should be attached to your bike somewhere…

With this inflator, you can use the 12 gram non-threaded Co2 canisters from just about any manufacturer. This inflator is very robust – not cheaply made at all. The trigger mechanism to release the Co2 into the tire is very convenient. You control the flow, fast or slow.

This CO2 inflator comes with one 16g non-threaded CO2 cartridge. Fast fill, just put a go! You never stop cycling for flat tire. Is easy to use and it is priceless when you can go many miles without worries to stop and end your trip because have a flat tire.

The item itself seems very well made and it is in a pretty compact package. You’ll be glad to have this little emergency pump!

The Benefits of CO2 Inflators

Single-use compressed air CO2 (carbon dioxide) cartridge pumps can quickly inflate tires.

Different sizes of cartridges are available, with most cartridge pumps being able to use more than one size. Depending on the following, one or two cartridges may be needed to fully inflate a completely flat tire:

  • Size of the tire.
  • Size of the cartridge.
  • Recommended tire pressure.

To save on cartridges, a hand bike pump can be used for the easy initial inflation. Cartridges are then used to top up the pressure, when hand-pumping becomes too difficult.

question-markWhat You Should Know Before Buying a CO2 Inflator

From a variety of bike pumps available on the market, you will come across an advanced device, known as CO2 Inflator or CO2 Bike Pump. Being the most advanced bike pump model, this type is utilized by professionals and serious racers. Before knowing more about CO2 pumps, let’s have a look at what a bicycle tire pump is and how it works?

A bike pump usually comprises of the following components:

  • Pressure Gauge (some types do not incorporate pressure gauge)
  • Valve (Presta/Schrader)
  • Hose

Using compressed air, a bicycle pump is able to inflate the tires with the correct pressure. As the cylinder is compressed, the air is pushed down the tube through a valve. The pressure in the air forces the valve to open instantly and when the handle is pulled up, the valve shuts off automatically so that air cannot escape from the tire.

The CO2 bike pumps are designed to be the fastest way to inflate tires with the correct pressure. These pumps use replaceable CO2 cartridges, which make the entire process very fast. There is a lever on a cartridge that is broken and the air is pushed into the tire valve quickly.

Since these pumps contain carbon dioxide, the tires will go flat within a few days, because the CO2 molecules leak easily than air. This is the reason why you need to have CO2 cartridges with you… so that you can pump up the flat tires instantly. You can also find inflators, that feature a pressure gauge on the top side, in order to display the correct tire pressure.

Quick, only seconds. Good for inflating tires when cycling in a group, to reduce disruption to other riders.

Provide accurate pressure information

Limited capacity. Need to carry a few cartridges. Possible to run out of cartridges if more than one flat occurs.

Can freeze up during use in cold weather. Using the cartridge decompresses the contents, causing the air temperature to drop.

Replacing cartridges can be expensive in the long run.

Not very efficient as the tires need to be inflated within 2 to 3 days because of the CO2 molecules.

questionWho Should Use CO2 Inflators?

The CO2 bike pumps are suitable for the following users:

  • Professional racers and cyclists
  • Semi – professionals
  • Users who need to inflate tires quickly

yes-or-noValve Compatibility of CO2 Bike Pumps

Being a major component, a valve needs to be considered first before buying a Co2 inflator. There are mainly two types of valves:

1. Schrader Valves

2. Presta Valves

Schrader is the type that is usually found in ordinary models of bikes (like mountain or kids bikes), while the Presta valve can be found on high-quality racing bikes. If you buy CO2 inflators, you will benefit from the advantage that they are usually equipped with both Presta and Schrader valve connections.

How to Inflate a Tire with a CO2 Inflator

A CO2 is a compact, lightweight and portable alternative to bike pumps but is a one-off solution. There’s a nozzle/inflator and a cartridge holding the CO2. Steps to use your CO2 tire inflator are:

1. Release remaining air out of a bad tube. Check for puncture and repair it.

2. Connect the inflator’s valve head into the Presta or Schrader valve.

3. Once you are sure the connection is tight, screw the cartridge to the inflator.

4. Inflate the tire and if need be add another cartridge if you are using a high pressure tire.

5. Check tire clean lines for bumps and correct them.
