LEZYNE ABS-1 Pro Chuck Bicycle Valve Head, Presta & Schrader Compatible, High Performance, Bike Valve

A little over a month ago, I replaced an ABS-2 pump head with an ABS-1. So far I am quite pleased. There is a great deal of contrast between the two designs. The ABS-2 is a marvel of engineering that somehow just doesn't work well. If I pay that much for something, I want it to work and to last for a long time. It did neither. The concept was just overly complicated for its pricepoint. The ABS-1, on the other hand, is brilliant in its simplicity and the quality of construction on my sample is excellent. It works!I spent over 45 years in manufacturing, starting as a tool and die apprentice, earning a journeyman's certification, working in design, quality control, and teaching. If a simple design does the job well, I'm all for it. The ABS-1 should outlast me.

I have a cheapy Blackburn pump from years ago and the pump head met its end. My pump works pretty decent so I took a gamble and bought this HV pump head. First, without opening the package, I found a bolt with a similar size as the end of the pump head. I forced the bolt into the open end of my Blackburn pump hose. It fit. So, I opened the package and tried the pump head. Nope. So, I used the tip of some pliers to stretch the hose (picture). Then I put a drop of hand soap on the new pump head...with some work I got it to go on. Now my old Blackburn has a sweet Lezyne pump head! And, this pump head is nice! It's slower to use than slip on / clamp on style of universal head... but there is a reason I replaced that head! The Lezyne screws on tight, has a bleed valve and even has a presta tool on the back of the head. NICE! If you are going to do the same thing, I'd estimate that if you can squeeze your hose on something 9mm or about 3/8 of an inch, you can use this Lezyne pump head.

I purchased this as a replacement for an old pump head. It's a little trickier to use than a standard head but worth it in my option. It works perfectly for a shrader valve but there no way to bleed off tire pressure while attached to a presta valve. The little button on the side bleeds pressure between the pump and the head, not the valve. Other than that, it's a win for me

High quality and one of the few valves for a bike pump that screws onto the tire valve, making it easy to pump a tire by yourself, including high pressure tires. No more fiddling with the rubber seal that never works right, no more air releasing as the hose pulls to the side, no more air release as you pull the valve off and no more banging your hands on the tire trying to pull it off quickly. It has a button to release the pressure in the hose before you take it off, so it unscrews easily and without releasing any air. All the details are right, including clear labels for the Presta and Schrader sides.A few things to know:- Not all pump hoses are the same size, some hoses are larger than this is expecting, but you can shave down the hose with a knife and get it to fit.- This valve does not push down the release on a presta valve, so if the tire is already near full pressure you have to push very hard at first to get a higher pressure than inside the tire.

While the Lezyne abs-1 pro chuck looks well designed but for one main failure that precludes its use for standard pumps - the design does not allow fitting to standard industry pump tubing, only proprietary Lezyne pump tubing.The compression nut inner diameter spacing for 8.7mm OD pressure hose tubing, while industry standard Park Tool, Topeak use 9.8mm OD tubing. Another reviewer had to scrape / cut their standard pump tubing narrower to fit the compression nut.Response from Lenzyne:"While there are "common" sizes, there is no standard size of pump hose. We only design our parts to work with our products, and do not support modification or universal use."Interestingly the "Lezyne Abs Floor Pump Hose, Gold/Hi Gloss" states: "Compatible with all standard pressure floor pumps"

I have had the Lezyne steel floor pump for several years and it is a workhorse. I have had many floor pumps over the years looking for something that would be as durable and reliable as my old Silca - which gave up the ghost after a decode+ of use and abuse. Sure, this is not a 'quick release' chuck, but every pump I have had with one of those wears out. The upgrade with the angled chuck versus the straight chuck that came with the pump is a very nice to have. It is easier to attach, take a couple of seconds to spin on and there is a tight connection to the valve. Plus it works on presta and shraeder(sp?) valves with no problem. So far this chuck and the floor pump are exactly what I wanted. Great engineering and ergonomics.

Like one of the other reviews have said, it can take the Presta valve core with it, causing catastrophic failure. See my picture. I only used it once before, and then the second time this happened with a great explosion of air.To prevent this, you must use the black button to release some of the air stuck between areas of the device before starting to twist and remove.
