I needed to buy a high pressure pump for air forks & SFS air clamps. This Neken air suspension pump was reasonably priced & looked good on the Rocky Mountain site, so I ordered it. I was very pleased when I got it. It's very well made, excellent quality and works very well. 100% satisfied! P.s. This is not intended to fill tires, but could in a pinch.
I bought this with out doing any research to compliment my Tubliss tire set up (AWESOME!!!), which requires up to 110 psi.
This pump handles that with ease. However,
It's a weird size. Kinda too big for a pack, yet too small to move a lot of air.
On the inner bladder, you don't need much air to maintain the 100-110 required. No problem there. The threaded nozzle is on a hose that could be an inch longer, but at least the threads are such that you lose almost no air when removing the chuck. This is important for the Tubliss set up, since you need high pressure in a small volume space.
But it would be a pain to pump up a regular tire. This pump hits high pressures a tiny bit at a time.
Because the gauge reads up to 300 psi, you can forget about accurate readings at dirt bike psi. 18 wouldn't even budge the needle.
The body and handle of the pump are beautiful and have a nice feel. The gauge seems flimsy and fragile by comparison. The pump action is smooth.
This pump is quirky, which I like (Michelin shrader tire gauges, anyone?), but it's usefulness is a bit narrow. I've come to realize that this pump is probably meant for suspension tuning, not for inflating tires. It's also OK for maintaining the Tubliss system, but a conventional HP bicycle pump would be at least as good and better able to handle large air volumes.
