I'd be interested in hearing from anyone who had this problem with carry-on. The only reference on the TSA website is under "bicycle tire pump" where it states this item is okay as carry on or checked. They can't be referring to small hand held pumps because they also suggest checking with airline to ensure it fits under seat or in above bin......which it will if its inside your carry on bag. Again, appreciate hearing any feedback from those who have taken pumps as carry on. I also ordered the same pump and plan to carry on with my next trip in August.

I just found this:

Check or Carry-on
You may transport this items in carry-on or checked baggage. For items you wish to carry on, you should check with the airline to ensure that the item will fit in the overhead bin or underneath the seat of the airplane.
To help officers get a clear look at your bag and reduce the need for additional screening, we suggest you pack your bag in neat layers (layer of clothes, layer of electronics, layer of clothes, layer of shoes, etc.) and wrap cords tightly around electronics items.

Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with TSA on whether to allow any items on the plane.

Great, even though it is allowed, it can be rejected. I'm glad we got that cleared up!

''Sweeney - you can both crush your AG *and* cruise in dead last!! 😂 '' Murphy's Law

I got the Lezyne Travel Pump on Thursday and just used it to pump up two bicycles, 4 tires. I'm 6'0 so it feels really low when I'm pumping but it pumped up just about the same as my full size Lezyne. This pump will fit nicely in the bike case with my wife's size 52 bike. The screw on chuck is no big deal. I couldn't get in on my H3 but I do have a crack pipe so I just have to make an adaptor to get it to fit.

All around I'd say it's a win For short trips i can skip the checked bag and for longer trips it won't take up as much room as the full size pump.

Does the Lezyne chuck thread onto a Presta valve and fit inside a Zipp disc cut-out with a 51mm valve stem (common for latex tubes)? I'm looking for a solution where I don't need three hands to pump.

I could get it to lock on to a 48mm valve stem in a Zipp disc. pumped up my own tires in transition.

Get outside!

I've replaced the Lezyne chuck with one of these:

This allows me to bend the valve very slightly on the disc (I have a 2009 Zipp with a dremelled cut out, so very small) and screw on the hose. It also screws on to the valve extender on my 808 front. Works perfectly for me. I found the standard Lezyne chuck wouldn't do my disc, and nor would the speed chuck.

Haha - Good one! I can't believe 8 years either. I watched her cross the finish line then!

The Lithium-Ion battery is fantastic. Used 3-5x a week, the charge lasts 2-2.5 months.

Interesting option. I already have several Craftsman C3 tools and 5 Li batteries. That pump + battery would definitely be heavier than a small manual travel pump but in my bike bag I guess a pound or two really doesn't matter. I'll check it out but I'm leaning towards the Leyzene if I can work out a good thread-on solution that fits my Zipp Super9 disc.

i'm a big fan of my Lezyne Travel Pump for race day applications. It can pump to high pressure, has a pressure guage, and overall excellent fit & finish. It's biggest downside is it looks like an expensive pump, so when I loaned it to my GF last year for 70.3 Worlds and she loaned it to someone in transition, that a-hole decided to abscond with it. I hope he flatted and DNF'ed!!

But I bought another as proof that its a great pump. And I no longer allow anyone to walk off with my pump. If they're too lazy to bring their own to transition, they can bring their bike to my rack.

I have the Lenzye compact pump as well and it works great. But if you want to go REALLY SMALL, I use this:

Lenzyne Micro Drive HP Pump (with guage)

I swapped the heads for both of the lenzyne pumps with a Top Peak Smarthead.

TopPeak Smarthead

The TopPeak head add some extra hose and more bulk to the pumps but they work flawlessly and with any kind of valve.

The micro drive is a little harder to pump than the compact but its much much smaller and i'm pretty sure it's carry on friendly.

CO2 doesn't work with latex tubes
