    Did you two use the small or the medium version of this pump? Actually I’m a little confused because Amazon appears to list four sizes, small, medium, 166, and 214 mm.

    I’d like to get one to use with our Bromptons and other bikes, but I’m not sure what size to order.

    +1 on Lezyne quality and flex hose. I bought a Pressure Drive model way back when I liked high pressure tires. Today I would choose an Alloy for fewer strokes.

  • I used to have trouble with stems being torn off by a pump till I learned to just hold the pump and wheel together with one hand while pumping with the other. THis way any moving of the pump moves the wheel with it and the valve stem takes minimal twisting or bending. Still if this is a problem for you I guess you have found a solution. I found the more joints you have in a pumping system the more leaks you get over time.

  • David,
    It’s good to have proper pumping technique. What’s nice about the hose is that it makes it almost stupid proof, which comes in handy when you are tired or fatigued and aren’t thinking particularly straight (or if you’ve got the last 16 inch tube for thousands of miles around).

    I just ordered mine. It’ll go well with my Brompton which got here last Friday.

    Cool little pump. I like the flexible hose. Is there a version with the quick release that is normal on many bike pumps?

    Good reviews look forward to more . I agree the brompton pump is just incase only . Just brought a dahon bike for my wife , this has a biologic seatpost pump . It would be great if brompton did one like it , works and very clever design .

    +1 on Lezyne pumps. The flex hose and screw-on schraeder connection are godsends, especially on folding bikes as well as baby joggers, Chariot trailers, etc. As my older, crappier bike pumps wear out or get lost, I’ll be adding multiple Lezynes to the lineup for various bikes in various uses. I currently use the “M” version sold by Velo-Orange for my road bike and couldn’t be happier. It fits in randonneur handlebar bags.

    One caution – some high end presta tubes such as the ultralight ones sold by WallBike have two-piece presta fittings which screw together. When you repeatedly use the Lezyne screw-on hose on those valves, over time the valve stems unexpectedly unscrew bit by bit with the hose…

    I can confirm they work great on presta values too love that pump and really like the water bottle mounted pump holder but could easily fit in my jersey pocket, very pleased with this product

    Its a great little pump, but ditto what JD said.

    The lezyne pump WILL unscrew the valve cores of your presta tubes. And on tour you may not have the option of purchasing tubes with the “right” kind of valves.

    Any tricks to stopping the valve from screwing off. Using it on high pressure valves near ever time taking off the pump also separates the valve. A very limiting factor.

    After a few disasters with these Lezyne screw-on fittings I always undow the valve core when purchased and put a little Araldite (epoxy resin) on the thread. This prevents the problem.
