While they aren’t officially launched just yet, Lezyne are showing a couple of new pumps at the Taipei Bike Show right now, and gave us the okay to give you a sneaky first look. Prices and launch dates are TBC, but expect to hear soon.
First up, the Pressure Overdrive has a large volume air chamber that you can charge up, then suddenly release to seat a tubeless tyre. It has the ABS2 chuck, which is the new push-on Lezyne chuck, rather than the screw on ones their pumps have had before.
The Micro Floor Driver XL is in the same range as the Lezyne Micro Floor Drive that won our recent mini-pump grouptest. The XL is aimed at people with plus and fat tyres though, and because of its large volume comes without a frame mount, the idea being you’d carry it in a pack.

Does the Micro still have that screw-on chuck that everyone commented on after the Group Test? Seemed to pretty much rule it out as a usable piece of equipment.
It does appear to have the old style Lezyne chuck in those photos, but I’ve got three pumps with the same chuck and find it absolutely fine if my valves are properly tightened.
One thing I really like about it is that it’s much less prone to bending the tips of valve cores than a hamfisted attempt with a push on chuck.
I have never bent a valve with any pump but my lezyne has removed several cores for me. I haven’t tried the depressurising method yet (never thought of it) but for now I’m not at the front of the queue for another pump from lezyne that’s for sure.
If a particular design unscrews valves, and no other quality design does, blaming the operator is ridiculous. Lezyne had one previous attempt at fixing this issue, albeit they failed,but that’s pretty much an admission that there’s an issue. Replaced mine with a truflo that cost half as much and worked better, sorted.
Though I do like that XL
What?! people have an issue with the screw on chuck?
So it unscrews valves that weren’t done up tight? Yes I’ve had this happen on a newly fitted valve, I just did the valve up properly
For me the leyzyne chuck is one of the main reasons I went for it. The screw on is far easier to use than all the other push on and lock types that always seem to bent valves and/or wear out and leak
The old style Lezyne chuck is obviously even more divisive than a white and gold stripy dress.
Given that I’ve never had any problems with any other style of chuck I think I’ll avoid the possibility and stick to what I know 😉
No issues here – tighten your valve cores…pretty normal procedure in our household.
“Tighten your valve core” is solid advice, as is “always make sure you’re carrying a valve-core tool to tighten up your valve core on the trail in case your pump unscrews the valve core and dumps all of the air out of your tyre when you were just trying to firm it up a little bit in the middle of a long ride”. I’ve learnt the hard way to do both things.
But I can understand the appeal of a pump that doesn’t create the issue in the first place… 😉
But it’s black and gold coloured…….
Doesn’t anyone read instructions anymore!!?
The black button on the side of the ABS chuck releases the pressure in the hose (not the tyre!) which makes it easier to remove the chuck and stops the valve internal from unscrewing. So all the comments regarding valves unscrewing are because they weren’t using the chuck correctly.
To be fair, anyone who unscrews the valve core more than once with a Lezyne pump, well, Darwin had a theory about that…
I have a micro floor drive and a small road type Lezyne and have never had a problem with unscrewing valves. In fact on group rides where there is a puncture they all wait for me to use the screw on chuck rather than their core bendy mini pumps. This mainly applies to the tiny pumps that roadies carry in jersey pockets. I find the larger pumps mtbers carry are not as prone to bending valve cores but it does happen!
I’m liking the ‘chuckgate’ tag.
that is all.
Jellybike – older Lezyne pumps didn’t have that, only been added on the newer ones. Simplest solution is to remove the head and replace it with a head of your choice. I like Hirame…
“always make sure you’re carrying a valve-core tool to tighten up your valve core on the trail”
Or pliers
Or do them up when you worked on the bike?
Where can I get tubeless valves that don’t come apart in the middle? Like the ones (most) tubes have
@James – cut them out of dead normal tubes? Why would you not want removable cores though?
