Shazam(!) LET it work using the 3 steps.

I took in the instructions and did what I thought was the suggested way, but it took dropping back and beginning all new by simply using the exact “3quick steps” and shazam! The steps shown on the site were a bit better than on the box for me to get the hint. I had it 80% there but not 100% and stress free until letting those 3steps dictate. Heed the diagram’s lift arm rotations. Get it on with the CORRECT pin and hand rotate your derailleur as it says. It will simplify at that point.
If you want it to work, LET it work. Even in my initial attempts I did not touch the chain once. Now that I know the easy and QUICK way I will not ever want to even loosen my cinch cam without this guy. Will be perfect for transport without wheels in the trunk of my Camry. Completely clears my cassette and things should drop in and out quickly without any chain interference or attention needed to align things.

Easy as advertised!!! This thing just makes sense

Easy as advertised!!! This thing just makes sense. Easy on and easy off with no loss of tire presseure. Solid and rebuildable... This thing should outlast me!

Best pump ever!

Works the advertised! Made out of great materials! No tire pressure loss! The trigger release is so smart!

I have had several pumps that

I have had several pumps that, at best, were ok. This Zilch Floor Pump is awesome. I like the digital readout and its location on the pump. I also like how easy the pump head attaches to the Presta valves. The conversion to the Schrader valve is one of the easiest I've ever worked with. Overall, this pump is everything as advertised and I would highly recommend it.

If you struggle to take the rear wheel off & on like I do then this is the perfect tool to use. It's so much easier with Chainlift.
