Problems so no longer use
The first chuck broke with the screw top coming off when inflating the tyre. Wiggle sent a replacement but similar problems. So I switched to the traditional pump connection - a screw on. Nice concept but probably best just on low pressures and not the 90-120 psi on road/race bikes I use.

Poor quality, breaks easily, that's two I wasted my money on

I'd love some speed, chuck!
Chuck is a term of endearment in Britain's industrial north. Hence: "I'd love some speed, chuck!" (said in a Lancashire accent). This is an important addendum to the Lezyne pump, except the Lezyne pump itself leaves a lot to be desired.

Works as quick alternative to the screw thread
Let's face it, one of the big selling points of the leyzene pumps is the screw on heads.
But there are times when you don't want to spend the time steering the nozzle on to presta valves, or you might have a dodgy valve that unscrews completely.
This is for those times, it turns the screw on into a push on.
It also turns the head 90 degrees meaning it's a bit easier to fit into small wheels.

a must if you use a lezyne pump for a disc wheel
a definite must have if you use a disc wheel.
It''s a push fit onto the valve, so must be held on when pumping upto big pressures.
Can be left on the pump, but is so small it's easily lost!!

Simple and easy inflation for tri-spokes and discs
Not much to say other than it works well with the appropriate Lezyne pump to inflate my tri-spoke and disc. Fits easily into the cut-out of my HED D3 disc and H3 tri-spoke. Even bought a second so I keep one in each wheel bag.

Not up to much
I got this for my Zipp valve extensions as the screw on type of adapter does not fit on.
This just pops off the valve as soon as you try and inflate over 40psi so you have to hold it on by hand and pump at the same time, not ideal.
its a bit rubbish really.

I have used this a track pump that was getting a bit boring screwing it on and off valves when using it and it is great save much faff. I have only used it on MTB so far so don't know about higher pressures of road bikes.
Really it would be great if the pumps just came with it

Good piece of kit but wears quickly
Just press on to the inner tube valve and inflate - couldn't be easier.
Works perfectly until the thread that connects it to the hose wears.
When this happens the high pressure on road bike tubes constantly pops the connection rendering it useless. My last one lasted a year. By all means buy it but be aware you may need another after a few months.

bought this because it seemed easier to use than the normal chuck that comes with lezyne pumps. the problem i found was that if you want to inflate your tyres above 90psi then the chuck blows off the valve. maybe i am not using it correctly but seems a bit of a waste of money really.

Too big for older zipp discs like the 909
This is a plastic adapter, not very well made, and also a bit big if you like me have a disc wheel with a small hole and a "long" valve (40 mm on my Continental sprinter tire). It fits on the valve when I have an empty tube, but when it's filled, the speed chuck will be stuck in the disc since it's too big to remove.
I ended up using the "Zipp Disc Wheel Track Pump Adapter" together with a small presta-schrader adepter I had for my Lezyne pump. The difference in height is about 8 mm, this one is 25 mm in height, and that's a big deal when it comes to small disc wheel cutouts.
I'm sure this will work for you if you have a bigger cutout then I have. Check before you buy it.

Ideal for valve extenders !
An essential bit of kit if you own a Lezyne track pump and need to rapidly inflate any presta valve, be that traditional threaded type or thread-less types typical used on valve extenders for deep section rims.
Note, if you own an older Lezyne pump that does not have the
ABS pressure release valve, you will need to get this as well.
