Lezyne Pressure Drive CFH

The Lezyne Pressure Drive CFH is a well-made, easy-to-use and pretty well-thought-out hand pump and CO2 combo that can be used on both Schrader and Presta valves. The mount isn’t the best, though, so if you like to keep your pump on your frame it needs a little more care to make sure it stays in the right place.

In use, the pump action is decent; it does a good job for smaller top-ups or to get you home. As is the case with most mini pumps, there isn’t a pressure gauge, so you’re reliant on knowing rough pressures by feel. (If you don’t know what pressure you should be going for, check out our feature, How to choose the best bike tyre pressure.)

The Pressure Drive CFH comes with a detachable extension hose – the CFH part of the name (CO2 Flex Hose) – for use with the pump and the CO2 inflator. It has a reversible chuck at one end, with both Presta and Schrader fittings.

I recommend screwing the hose onto the valve first before attaching the pump to it, as this helps prevent twisting the valve, especially with tubeless setups. There are o-rings and seals to prevent air leaking out; you just have to make sure it’s done up tight before you start pumping.

Another thing to be aware of is that you can pull out a removable valve core if you’re not careful. This can be really annoying, especially if you don’t have a core removal tool on you, which could leave you stranded. This tends to happen when the o-ring grabs the valve core too tightly and pulls it out.

Using the pump is straightforward, and while it’s never going to be as quick and easy as using a floor pump, it does a fine job out on the roads. From flat, I got a 25mm tyre up to around 70psi in 160 strokes and about two minutes of pumping, which is pretty decent for a smaller pump.

CO2

Using the CO2 canister is easy, too. Again, I’d recommend threading the flex hose onto the valve before screwing the canister into the other end. As with most inflators, once you’ve screwed the canister onto the hose you need to unscrew it a little to actually release the gas, once the seal has been broken.

It’s more or less a one-time-use thing, but if you have a larger canister, or don’t fully empty it, you can screw it up tight to save it for another day. However, this does mean you’ll have to keep the hose attached, so it isn’t the most practical way to use it – you can’t stow it away in the pump.

The Pressure Drive CFH comes with a foam sleeve which, wrapped around the CO2 canister, does a good job of protecting your hand from the cold.

Mount

Mounting the pump and canister to your frame is a bit fiddly, and requires a little more care than most to make sure the pump stays in place. You have to put the CO2 canister in its sleeve, and then use a strap to hold the pump and canister in place; you can’t just put the pump in on its own.

You also have to make sure the pump is in the right way around; if you put it in the wrong way, it can fall out.

Value

At £45, the price isn’t bad for a two-in-one pump and CO2 inflator. You can easily pay £30 for a mini pump and a further £20 for an inflator, so this feels like a reasonable deal.

That said, a similar design that comes in cheaper is the Cannondale CO2 Road Mini Pump that Hollis reviewed in 2022; he thought it was decent overall, though the pump lacked power, and you only have the option of Presta valves. But it’s £32, so a £13 saving.

If you’re happy to buy separately, a classic and cheap option is the Topeak Pocket Rocket, a standard mini pump that does the job for £19.99.

Another mini pump I reviewed last year, the SKS Airflex Racer Black, is a very good option – one of the best I’ve used – but then it comes in at £38 without the CO2, so pricier than the Lezyne, and it has the same potential to pull out your valve core.

For a standalone CO2 inflator, Jamie rated Muc-Off’s CO2 Inflator Kit, which, as well as being the fun pink colourscheme that Muc-Off is synonymous with, gives you a controlled release. It does cost £29, though.

Conclusion

Overall, the Pressure Drive CFH is a good combo that works well. It’s decent value, and a convenient and versatile solution for on-the-go inflation needs.

Verdict

Easy-to-use combo at a decent price, but the mount could be better
