The pump is tiny and stays on my bike. The "G" in its TLA stands for Gauge,pressure. Mine hasn't read higher than 50% of the tire's pressure (which may be fine when recovering from a flat). I rode a 40 mi "race" with it on my seat tube. I tried it out before that ride: it attaches and detaches to/from my presta valve stems w/o leaking any air. Pro tip: attach the valve end to the pump base then pull the hose onto the handle. Don't try to attach it while tensioning the hose.
The Lezyne Micro Floor Drive is an excellent pump! The gauge is accurate as cross referenced to my standard large floor pumps. The gauge is any easy read.
Inflation is a breeze up to full PSI, with not very much effort with his handy little floor pump.
This pump is so reliable, accurate and easy to use, that I have one in each frame bag of three different bikes that I have used on very long bike tours.
Quality to be expected from Lezyne. Light weight and sturdy, great for traveling either on or with your bike. Small handle and foot stabilizer make this pump a great tool for getting those last few 'difficult' pumps in if you're looking for high PSI/kp for your smooth roads.
Only (small) negative is the foot stabilzer is a little short and a bit challenging to 'grab' with road shoes on and sometimes feel a bit unstable as if about to bend. Pumping with focused patience needed (i.e., don't rush).
This is a fabulous travel pump. I usually use CO2 when I'm riding around my home town, but I take two or three cycling trips a year and since you can't fly with CO2 and I can't count on getting any where I'm going, I use this every time I travel. It is surprisingly effective pumping up road tires to good pressure. In fact, it can easily pump the tire to considerably higher pressure than is optimal.
Since it's got a nice long hose and a little tab to put your foot on, it's easy to pump up the tire without worrying about damaging the value (which is a common problem with most frame mounted pumps).
And it's amazingly light. It's easy to through in your bag, and even if you're a weight weanie, you can easily carry this pump on your bike without feeling like you're lugging a lot of extra weight.
Highly recommended.
This works like a mini-floor pump so you won't wear out your arms pumping up a 4 tire. I was pleasantly surprised how well the on-bike mount worked. After 100 miles of gravel road the pump hadn't slipped down at all. The only negative is that I have to store the angle attachment in my seat bag because of the way everything screws together to stow the hose.
Purchased this for our GDMBR trip this summer, which has since been cancelled. I did a "test" pump here at home and everything seemed to work fine. Great looking product.
Works great , compact, easy to vary as spare pump in car - even pumped up the car tire in a pinch!
Product seemed well made, but I didn't use it. It was larger and heavier than desired. Probably a good replacement for a frame pump, but overkill for my backcountry needs.
