New Pump Head - Kickstarter
I saw this mentioned on another site. Looks interesting. I have no financial interest in it, but would consider getting one.
Any comments, for and/or against??

Nice. It looks like the future, if you ask me.

Very interesting. Not to be critical, according to the site, the head is rated to 120 psi and the pump to 160 psi. While 120 psi is sufficient for most riders, shouldn't all parts of a unit be consistent and compatible?

Then it's a solution to the more difficult ones. I have a Giant pump that fits both valves without swapping parts, but seems the rubber is starting to leak when used with Presta. And it hasn't been used that much.

There are two problems with the usual heads:
1) the rubber wears out because they must be pulled off with some force even when the head is disengaged
2) eventually the valve stem pulls out of the tube due to problem 1)
My question would be: does this head solve those problems? No way to know without a few years experience with one.

The other thing I wonder about is how much stem you need to have exposed to engage this pump head. That's one problem I sometimes have with traditional pump heads. On the videos it seems like this pump head needs a lot of exposed stem.

Actually if these things ever go retail for $25, I'd be tempted. I dunno if I wanna spend $25 for a 50/50 chance of getting a pump head, though.

That was my concern as well. Not a problem on my own bikes, but when our club does our supported ride I provide SAG support and end up putting tubes in lots of different rims and some have pretty minimal exposed stems. But the concept looked good - seems like they do a more complete compression/relaxation of the pump rubber so the head goes on easier and comes off without need for much force at all.

My pump is a Lezyne with a threaded chuck. I don't see this as an improvement. I explicitly bought a pump with a threaded chuck because the rubber gasket variety just dont hold up.

Stick one of those puppies on my silca floor pump and get rid of the beastly large and incomprehensibly difficult to use pump head it came with and it might just be heaven on earth.
It does look like it requires quite a bit of valve sticking up above the rim... hm.

I read about this on probably the same other forum, think he said needs 15mm exposed. Not sure my tubeless valves have that much. They are close with my current pump head, which happens to work just fine.

The problem that I have with shorter valves is mostly because because of the force required to push the valve in to the chuck (particularly bad with uninflated/severely underinflated tubes). It's hard to say, based solely upon these videos, but it looks like this pump head might open up wider than the rubber gasket variety and require less force to insert the valve in to it. If so, I'd say that that's a win.

Ever since I broke the valve head on my floor pump (I have a set up for my air compressor) I have been looking for something that would easy to use and I won't break as easily. This may be the ticket. I backed it.

Decent replacement heads go for about $8. I don't see any reason to spend $29 on this.

The thing that I don't like about the Lezyne threaded chuck is that it can lefty-loosey the valve body right out of the tube (which is a huge pain in the ass when it happens). I suppose that the ABS probably mitigates this problem, but I haven't upgraded the tube on my mini pump.

Not much to it, I guess - the pump head screws on to the valve body in the same direction that the valve body screws in to the stem on the tube; which ever of those two junctions is less tight is the one that unscrews when you start loosening. I'm guessing that a build up of pressure in the pump tube contributes to a tighter connection between the head and valve body, and in that case the bleed system would help considerably, but I don't know for sure.
