On an empty tire it works great. At 10psi it gets tough to use. At 20psi it took all my strength to work the pump. I tapped out at about 25psi. No where near enough to be useful for inflating tires on the road. 90psi stated has to be aspirational for the World's Strongest Man competition. I used my floor pump to check the pressures alternating with this pump as I tested it before mounting it on the bike. I'm probably average strength for athletically oriented middle-aged men.

Lightweight and compact high volume pump

Familiarity:

I've put it through the wringer

The CNC aluminum construction keeps the weight low on this pump. I bought the medium size and it fits well in a backpack or hip pack. The small size is small enough to be carried in a jersey pocket. The barrel is actually pretty large so it inflates tires quicker than other portable pumps I've tried. The hose is nice for on-trail repairs because you have a little room to move the pump around vs. a design where the pump head attaches directly to the valve. Integrated storage for the hose keeps things clean. This is a high volume design so it works well with mountain bike and gravel tires, but may not be able to inflate road tires to high enough pressures. No issues with durability so far.

As with most Lezyne frame pumps, this one is equally as good. with the high volume chamber, pumping up regular mountain bike tires up to fat sizing is a breeze. With the added ease of the flexible hose, I don't have to worry about air escaping through the connection between the valve and hose, as well as, ripping off the valve to the tube.

Not Compatible with Tubeless Tires

Familiarity:

I've used it several times

This pump pulls the threaded inner part of tubeless valves out when used with tubeless tires. It's incredibly frustrating to need to pump on the side of a trail and then have it repeatedly pull tubeless valves apart. It may be a good option for high volume tubes, but look elsewhere for a pump that works with tubeless tires.

I always keep a spare tube and this pump in my pack! The pump is great because it is lightweight and pretty small. I always buy Lezyne products because you can purchase replacement parts for their pumps. The HV pump is perfect for pumping up mountain bike tires quickly. I would recommend this pump to anyone!

I was up in a mountain and noticed that the back tire was a little low on air, I was glad I carried this pump to avoid issues during the return.

reviewing again because I bought 2. These are amazing - the other day I got a small sidewear tear that the stans wouldnt repair, and this thing had enough juice to inflate it faster that it would deflate to let me ride out the last mile of trail (with a couple inflation stops)

Mount this under my water bottle cage, it's a really solid connection even with abuse on my mtb. It's a high volume pump, much easier to inflate 29" tires than other pumps I've had. Seems really high quality and I like the detachable hose, makes it a really easy process. I now have one for each bike

Perfect!

I bought this as a backup- I usually use C02- and its perfect. Its light, fits perfect into the Osprey Tool Roll, and pumps up tires. The hose is also a plus because you don't wreck your valve stem when you are pumping. Sweet!

Perfect size!

Fits in the back of your jersey perfectly. Easy to use, highly recommended.

Sweet Design

This unique design works very well. It is compact sitting in the mounting bracket, and delivers good pressure when hooked up to the extendible hose. The hose also provides some nice flexibility, so you are less likely to break a tube anywhere around the valve.

Great design

This isn't like your traditional pump and you have to screw in the hose. After buying a pump online and having the pump be worthless I was hesitant as I didn't want the same experience. However, this pump works like a champ and comes apart for easy storage in your pack, definitely recommend.

This thing will get you home. Supporting both a cartridge and a manual pump is key for days when the air just won't stay in the tire.

light and compact. i like how it uses a hose which makes it easy to use and can also store inside for saving space. Pumps my tubes pretty quick and efficiently

Good design

I've had quite a few mini-pumps before - some good and many bad. I've gotten to be very picky when it comes to buying a pump. So far I am very please with this one. Its small size belies its appreciable output. The ABS hose also impresses. The hose makes it much easier to quickly and securely connect the pump to a valve stem.

Works great

I bought the small size from backcountry a few weeks ago on a killer 50% off deal. I wanted a compact, reliable pump as a backup to CO2. I used it for the first time last weekend on the trail. I came across someone trying to add air to their tire. Her pump was broken, so we used this one. No problems at all. It takes up minimal space in a hydration pack & works on Presta & Schrader valves.

Valve stems need not fear.

Love this pump for its portability and compact design. It is the first pump I've owned that uses a hose to attach to the valve stem which prevents damage and stress on it that usually leads to failure. This thing is barely noticed in my pack and always there when I need it. I can get my tires pumped up and ready to roll in a few minutes until I get to a floor pump at my house.

Does this come with or is a cage mount available?
