P.O.S. Looks cool, works horribly.

Lezyne might have their marketing dialed, they might have Cavendish to promote their products, but my experience so far with all their product is less than satisfying. I've been around bikes my whole life, have used dozens of pumps and the Road Drive CFH straight up sucks. I bought one for my wife because the hose makes it easy to NOT break valve stems—but 9 times out of 10 when you attempt to unscrew the hose from the Presta valve it unscrews the valve core letting all the air out of your tire. My wife had tons of issues with this, one on the side of the road. I figured it was her, so I tried to use the Road Drive again & again. It pulled the valve core every time! If you screw it on enough to get air in the tire it pulls the valve core, if you don't screw it all the way on it doesn't get air into the tire. It may look great but it's worthless.

There have been several claims of removing valve cores from individuals over the years. There are essentially two was to combat this. One is to tighten the valve cores before using the tubes. This can easily be done prior to your ride using a pair of pliers. This procedure can become like any pre-ride inspection just like checking your other essentials. This quick step can ensure that you will not loose air along the way, and when you do have the unfortunate event of a flat tire the tube can be patched or replaced with relative ease. The other way to combat the issue is to purchase tubes with a one piece valve stem/core, but that is not always an option in a pinch. The Road Drive CFH was designed to be a versatile essential to any ride combining the ease of CO2 with the reliability of our award winning Road Drive pump. All Lezyne products are built with the cyclist in mind as we at Lezyne are all cyclists... We use and abuse all of the products we design prior to release to the public.

In response to your advice about tightening the valve core, that's great, but unfortunately I don't carry as set of needle-nose pliers with me on my rides. Secondly, when I help out a fellow cyclist on the side of the road by attempting to add air to their tires, and end up pulling the valve core on their tube because THEY also don't carry pliers with them it's really frustrating. SO, I stand corrected, IF YOU BUY THIS PUMP MAKE SURE YOU ALSO PURCHASE A SET OF PLIERS TO CARRY WITH YOU ON EVERY RIDE BECAUSE INEVITABLY YOU WILL COME ACROSS A VALVE CORE THAT ISN'T COMPLETELY TIGHT... OR YOU COULD JUST BUY A BLACKBURN PUMP.

Also, if "there have been several claims of removing valve cores from individuals over the years," maybe Lezyne should fix the problem? Just a thought.

It's interesting that chaz is indicated as a current employee of realcyclist.com. Do all your employees tag the products you sell as "P.O.S."? How classy.

I do not own this particular pump, but I have the Lezyne Pressure Drive and the Classic floor pump, both using the same screw-on connector as this one. I've used these two pumps on seven bikes and a variety of tubes over the past two years. I've unscrewed a valve core exactly once. I've also used a Blackburn as chaz recommends, and I can't count the number of times I've bent a valve stem or ripped a hole in the tube due to torquing the pump directly against the stem, rendering the tube unrepairable. So which shall we blame? The pump or the POS tube? In the ONE case where I unscrewed a valve core, I blame the POS tube for not properly installing their core. It was easily fixed by tightening. In the many cases where I've ripped the valve from the tube, I blame the POS design of a clamp-on pump where you are forced to torque against the valve to achieve rideable PSI. Opinions vary. I think this review by chaz is unwarranted.

The better solution is to use Michelin or Vittoria tubes with non-removable value cores! The Vittoria tubes are about the best on the market. The Michelin A1 Airstop Tube holds air the longest. Now you can leave your pliers at home. BTW broken value stems often result from having too long of a value stem in the first place. Pick a shorter length stem to avoid this problem.

i too have had valve stems come out....easy fix use the the brass schrader adapter, works way better no air loss when unscrewing the hose, should have one on bike for gas station fills anyway...

You might have over-tightened the hose onto the valve stem and permanently smashed or cut the little red "O" ring to the point where it no longer functions properly. Replace the "O" ring, and your pulling-cores problem should go away.

Many of my training partners ride with Lezyne pumps, and we never have problems pulling cores. I personally ride with just the hose (purchased as a replacement part, sans pump) and some CO2 cartridges. It works great.

I bought a Pressure Drive CFH pump for my 12 year old Boy Scout so he could pass his Cycling Merit Badge. He was able to inflate the tires on his Trek to 110 psi by himself using both the pump, and the CO2, both without pulling cores. Did I mention he is twelve?
