The Speed Chuck is a great add-on to Lezyne floor pumps. It screws onto the Flip-Chuck head at a right angle to make it easy to fit in a disc wheel's valve cavity. It uses washers so you can just press on the chuck without fiddling with screwing on threads. And because it's added beyond the Flip-Chuck, you still have use of the bleeder valve.
While the Speed Chuck comes standard with all current Lezyne floor pumps, it can be lost. And older pumps didn't come with it, so it's a nice upgrade if you've had your Lezyne for a while.
The Lezyne Speed Chuck is a Presta-only Slip-Fit System adapter designed for fast valve engagement. The 90-degree bend is compatible with disc wheels. The 2-piece Composite Matrix design makes replacing O-ring seals quick and easy. It is compatible with all ABS Flip-Thread Chucks and available on all Flip-Thread Chuck equipped pumps, and the color is Black.

Worthless for road bikes. Good luck getting it to stay on more than 5% of the time with anything over 70psi. Mine is going in the trash before I toss the entire pump.

Thanks for this
I have two older Lezyne pumps (floor and mini-floor for riding with). They did not come with the speed chuck and I subsequently ended up with some VERY frustrating moments when my valve stem cores came unscrewed inside the pump's chuck. So thank goodness they made the speed chuck adapter, I love it. I loved everything else about my Lezyne pumps and I didn't want to replace them. This is a great solution. You may need to hold it in place for the first few pumps, but it's a minor inconvenience compared to pulling out the core and losing ALL the air you just pumped in, AND needing to replace that core...

Spare or Replace
Lost your speed chuck on your new Lezyne Pump? No need to fear, the replacement chuck is here! Nice little design feature of lezyne with the speed chuck. Quick and easy for a quick pump.

Have a pancake motor on the front wheel of my hybrid bike. Have just under 1/2 inch clearance between edge of motor and top of fill valve. Will this chuck fit in that space? Also, what is the thread size of the air inlet?
