Lezyne Control Drive Co2 Bicycle Pump

Works as advertised.

Very compact and very well made just buy one for your bike and enjoy the convenience!

Works well.

The first bike ride the day after I received the Lezyne adapter the cycling gods struck and I got a flat. The roadside repair went quickly, the adapter was easy/straightforward to use. This was my first time using a c02 cartridge so I was a little apprehensive, however just ensured the adapter control was closed, the adapter screwed onto cartridge completely, the adapter seated snugly atop the valve and slowly turned the control to release the c02 into the tube and voila !So much easier that using a pump and great to be able to fully inflate my road tire(s) at the roadside. I will still be carrying a pump for that day when the cycling gods are really angry and I run out of cartridges (I plan to pack 2 cartridges).The Lezyne adapter appears to be well made and is really compact and easily carried in my under-seat cycle pack. The sleeve for the c02 cartridge is a snug fit but worked a charm, no frostbite. All in all a great option for getting back up and riding quickly at full pressure.I will update the review if I run into any issues with the durability etc. of the adapter.

Like the adjustable for 70 PSi or 85 and not all the air in the canister.

BUYER'S "BEWARE" ALL THAT LOOK GOOD AND PRETTY, MAY NOT MEET YOUR LONG TERM EXPECTATIONS. IE: I HAVE NEVER HAD ONE OF THESE "CO2 BUSINESS END ATTACHMENT VALVES" LAST FOR MORE THAN A SINGLE USAGE. THE LAST PURCHASED, "BEFORE" PURCHASING THIS ONE" ONLY ALLOWED A SINGLE APPLICATION BEFORE THE "CO2's PIERCING NEEDLE BECAME EITHER, BROKEN, OR THE PIERCING NEEDLE'S "SHARPENED EDGE" BECAME DULL OR BROKEN...WITH ONLY THE FIRST APPLICATION. SECOND ATTEMPT OF A "FLATTENED TIRE" REINFLATION WAS NOT POSSIBLE. AGAIN "JUST SAYING" I'LL BE PLEASANTLY SURPRISED IF IT GIVE US MORE THAN SEVERAL INFLATION! HOPEFULLY/PERHAPS AMAZON WILL ALLOW ME TO PROVIDE LONG TERM FEEDBACK. BECAUSE, THIS GUY "ME" RIDES A BUNCH OF MILES EVERY YEAR. I'VE BEEN RIDING "REGULARY" FOR OVER 20 YEARS, AND AS LUCK WOULD HAVE IT, I'VE HAD BUT ONLY ONE OR TWO FLATTEN TIRES IN THAT PERIOD OF TIME. MY HOPE IS: THIS IS ONE OF THE TOOLS IN MY SEAT TUBE BAG, THAT I "NEVER" NEED TO USE AGAIN. SO WE CYCLIST CARRY THESE SILLY DEVICES WITH US, WITH THE "HOPE" THAT ITS ALWAYS SOMEBODY'S ELESES TIRE THAT GOES FLAT, NO NEVER "ALMOST NEVER" DO I EVER HAVE A FLAT TIRE... I'M GOING TO BE SORRY I'VE EVER MADE SUCH AN OPTIMISTIC PREDICTION!!! I KNOW IT, I KNOW IT, HOW COULD I EVER SAY SUCH A STUPID THING!!! I'M DOOMED... I KNOW IT! KEITH M

Great regulation of co2 flow. Being Lezyne, well made.

If you use CO2 to inflate your tires during roadside emergencies then you need this part! You screw the CO2 cartridge on to it, the. You put it over your Presta (or Schaefer) valve stem? And use a dial to begin and to regulate the flow of CO2 into your tire. It works so much better and easier than cheap inflators that don’t allow you to regulate the flow. This is definitely the o e to have.

I bought this a few days ago, together with some CO2 canisters, for some non-bike-related inflation purposes. Beautifully made, this is one tiny gem of an item - but why only 4 stars, rather than 5?Simply, it is NOT advertised or explained that, although this valve will mate with and inflate a Schrader valve (as found on cars, motorbikes and most mountain bikes), it IS NOT THREADED.In other words, you have to HOLD it down onto the valve with hand pressure, before you release the CO2. You cannot screw it onto the valve threads.And guess what - the Football needles I bought separately, for my actual intended purpose, therefore could not be used with this thing.I'm keeping it, as I do have a mountain bike, and it could be useful to have with me when out and about. But I have since bought another product from Amazon, which is almost identical, but which DOES have that all important threaded connector (PRO BIKE TOOL).

I had a cheapo version of one of these that left me with frozen fingers, a flat tyre and a long walk. I went back to carrying a mini pump until getting one of these for Christmas. So much better than old one. Screws securely on the co2 canister and has simple adjustment to control the gas flow. I had a few practices before heading out for the first time with this which was well worth it. My experience has been that presta valves are a bit more fiddly than schrader, particularly with cold hands so I take a little screw on presta /schrader adaptor with me. Had to use it for the first time out on the trail today. Little blast of air to put some life in the new tube before installing in the tyre (having dug out two nasty blackthorns that were too much for the slime filled tube) and then used the rest of the canister to get the tyre (29er) up to a rideable pressure - standard canister just about does it.Comes with a little neoprene cosy for the co2 canister and you need it, the canisters get finger stickingly cold as the discharge.

Absolute best bit is the controllable valve. fits on the valve really well, you can screw your canister in with the valve shut and then open the valve to let the gas inflate the tyre. The control is very welcome! It's small and fits in your pack.Don't forget Co2 canisters, none included woith the head. Also, the sleeves for them! when the canisters dispense the gas they get REALLY cold you need to buy the little sleeves for them to be able to hold them whilst filling your tyre . you get one free in the pack

I love this! Originally purchased with a box of co2 cartridges for fast inflation to re-bead tubless mtb tyres ( which it did), the variable control allows steady gentle inflation out on the trail. So much quicker an easier than a hand pump, I take this and a couple of cartridges in my back pack wherever I go, as it means changing tyre pressures for different types of terrain can be done in a matter of seconds. It also comes with a neoprene sock for the cartridge to protect your fingers from bottle freeze. Small, lightweight and practical, this is a must for any cyclist.

This is expensive for what it is but hey, it's Lezyne...and I can't resist they're quality over most other brands so I guess i'm willing to pay a slight premium for this.This is about as minimal as it gets, much better than other larger co2 pumps and won't take up much room in your saddle bag. As with other Lezyne products I find they work well so am happy with my purchase.
