    I wonder what the average number of installed spokes is before someone throws the whole thing out a window.

    This is exactly why I've never even considered building one of these I think for me it would be 1, maybe 2.

    (Tape is so easy to install and adds negligible weight, so I'll always choose that option rather than a wheel that is a pain to build or, heaven forbid, repair.)

    I wonder if you could do the same thing as in this video (at 2:46):

    I think you can, yeah. That video does make it look easy. Probably the second time I accidentally lost the nipple in there after removing the magnet I'd be kicking myself, though.

    (Honestly, I have never understood why people go through the hassle of putting in sealant through the valve stem.)

    Lezyne has a new design hose that no longer backs out valves. It is compatability with all the older pumps.

    I put sealant through valve stems every month in every tire. Why? Some tires are so hard to seat and sealant dries up in a few weeks.

    On their portable/hand pumps? I've tried a few Lezyne heads on floor pumps; the more traditional double-barelled head actually works well, but their other push on or "half-twist" heads worked terribly for me.

    I use the Silca push-on head on my Lezyne dirt drive now.

    For me sealant lasts closer to a few months, though it probably depends on a number of factors (?)
