High-quality floor pump. The valve holder (during inflation) is a real advantage for every cyclist. No more bent valve stems. High-quality material and a clear, practical design.

Works with ease and fits both of my bike with different pin attachments.

The attachment is wonderful, and it's paired with a nice digital display and air compressor attachment. I also absolutely love that it came with a wall mount. I think that shows an extra level of caring by the company and I appreciate that! I have it hanging proudly on my wall.

So glad someone took on making pumps simpler. I coach a youth triathlon program, and the few times I've tried to teach kids to pump up their tires it was failure at some level. I gave up on it. But, these guys decided to make things easier and they succeeded! Anyone can use it and that gives the kids more ownership of their equipment and gives me more time. And, I also love using the pump for myself. The attachment is the headliner for sure, but the pump itself is among the I've ever had.

I ordered the CHAINLIFT V2 because the last time I had to change a rear tire it was a pain to get the wheel off and on easily. I have a Shimano and SRAM derailleur, so I use two of the provided pins. I needed a new rear tire on my Shimano so I used the CHAINLIFT for the first time. I had to tinker with the rubber frame position but it was simple. I was surprised at how easily the system worked to disengage the chain and allow the wheel to drop out. I hope I don't have to use the CHAINLIFT too often, tires aren't free, but when I do need a rear tire change I know it will be an easy task. Great job on this system.

Better than the park tool shop inflator. Precise as well

I love it! Easy to put on and off without any air loss. With the digital meter, there’s no guessing. Beautiful piece of engineering.

The ChainLift is a game changer for me!! The good old flip the bike upside down and fight with the chain & derailleur is in the rear view forever now. I dragged my feet for months haggling on the cost but I must confess it is worth EVERY PENNY!!!!

This pump simply makes airing up bike tires enjoyable. I might actually look forward to losing air in my tires now.

I’m impressed. I’ve owned a few good quality pumps over the last 40 years. Some were even worth the expense to replace the head and keep them in service. That time came again and I decided to give this pump a try. Hands down the easiest to use. Great job.

Best pump I've owned -- great presta valve attachment

Love the pump, especially the ease at which the trigger settles down on the valve stem, also love the great locking lever that holds in in place!!

Pump is easy to use and the release is great! I bought the schrader conversion valves and they work great

The overall design change for airing up my presta tires is exactly what we needed! I have always felt other pumps worked backwards from what my common sence would think! My only complaint is it feels a little to plastic. The pump handle feels flimsy when you push down. The little orange end caps flex under load. I think a one piece pump handle would makefeel more solid. Other than that it works perfect and I have no reason to go back to my old pumps what so ever!

Once again, Radian/Chainlift has created an awesome product!! The floor pump with Zilch is now my go-to floor pump. It allows for one-handed connection that adequately locks it to the valve. It stays connected until you intend to disconnect it. No air loss when disconnecting. The digital gauge is also spot-on. I checked the air with a separate tire gauge and it reads exactly as the digital pump gauge. The pump is very well constructed...well worth the price. Makes pumping my bike tires fun again!!

There is nothing like this. Very easy to use - does exactly what they promised. Great product!

This pump is a game changer! It works Exactly as advertised. The pump head drops right in the valve, fills very quickly, and releases with NO air loss. There is no torque on the valve stem which was always an issue with all other pumps. The attention to detail is amazing. It is better than I envisioned.

I have only used the pump about six times, but so far it has worked flawlessly. The head works as advertised. There is no loss of air when I remove it, and it is so easy to install on the inner tube valve stem. I also love the magnet that holds the head in place. Time will tell if the pump will last as long as I hope.

A wonderful piece of equipment. A bike pump completely reimagined. With my old Airquip pump I would lose half the pressure in the tire just trying to get the pump head to attach to the valve. This Radian pump is foolproof

The pump head is the game changer with this pump. I have 3 other floor pumps, with different heads, for my bicycles. This pump's head and digital pressure gauge allows me to easily put the pump head on any of my, presta valve, tires and get an accurate pressure read. I have arthritis in both hands and this pump head is so much easier to put on and seal over the valve than any of my other floor pump's heads.

It took a while, but the floor pump finally arrived. The first time I used it. It worked perfectly. It seated on the valve stem without any leaking and the digital readout provided me with accurate pounds per square inch. It works as advertised. It is probably the best pump that I have ever used because of the ease of applying the pump to the valve stem and the way it locks and the way it releases.

Easy to use. Clicks onto the stem and holds securely. Tire pumps with the first pump action. No need to start pumping and then disconnecting , blowing air out of the tire and trying again as with most pumps and Presta stems. The gauge is large, at the top of the pump, not the bottom, and easy to read. The magnetic storage of the pump head on the of the pump handle is brilliant. Easy to grab and even easier to put away.

So tired of the old style air chuck

It works Great, I love the positive attachment so smooth and effortless, great job, thanks.

Awesome tool. Works great for cleaning your chain with the wheel removed (pedal backwards). Make sure you fully understand how to move the arms. For example one of them ratchets one direction but you have to pull out on it to move it back.
