Finally, an easy way to pump your bike tires!

No Pushing No Pulling

SLIDES On | Thanks to the Diametral seal design the Zilch pump head slides on and off. That's because unlike all other pump heads, the Zilch head’s internal seals never touch the tire valve until you lock them closed.

Zero Air Loss

Tired of losing air every time you remove your pump head?
With the Zilch head you lose nothing, nada, zilch.
Zero loss, every time, no matter your skill level.

Quick Secure Docking

Take it easy on your back with a high placement handle dock. The auto centering handle assures the dock is always waiting for you in the right position. Super secure and fast one-handed docking
(also patented).

One Hand

A one-handed auto-locking lever so clever, it was also awarded a utility patent. The Zilch head was designed from the start to make attaching and removing the pump head to the tire entirely and completely one handed.
It's sized and shaped to be easy and comfortable to hold

Your Pump For Life

The Zilch head is fully user rebuildable and comes with a LIFETIME warranty. Our floor pumps have user replaceable parts.

Less Squinting

High mounted precision pressure gauge.
Easy to read.
Easy on your back

Less Tipping

Large steady base. Some say it's art.

Less Damage

If you succeed at knocking it over, the rubber ends on the handle protect your floors (and handle too).

FAQ

Is there really no force required to attach the Zilch head to my tire valve?

Its true! That was one of our three design requirements of the Zilch head. Only made possible by the opposing Diametral Seals which never touch the valve as you slide the Zilch head on/off the valve. All other pump head seals make contact/interference while you push the head on/off the valve.

How is there zero air loss when you release the Zilch head?

The Zilch head allows the tire valve to close BEFORE you unlock the opposing Diametral seals. This results in ZERO air loss every time. No matter your skill level.

Does Zilch work on Presta valves?

Yes, Zilch works natively on Presta valves. And you don't need to change your valve core like some other pump heads require.

Does Zilch work on Schrader valves?

Yes, with the included converter that stays on the tire. You screw it on once by hand on each tire and leave it. Now even your kids can fill their tires easily!

Does Zilch work on Dunlop valves?

Yes, with the included converter that stays on the tire. You screw it on once by hand on each tire and leave it.

Does Zilch work on Italian (Regina) valves?

Yes, Zilch works natively on Italian/Regina valves

What is included?

2X Schrader to Presta converter, 1X Ball needle adaptor. Stored in the floor pump handle storage and shop inflator wall dock

Does the floor pump have storage in the handle?

Yes. Roomy enough to store the included 2X Schrader to Presta converter, 1X Ball needle adaptor.

What is the puff of air I hear when unlocking the Zilch head from the tire valve?

That sweet puff of air sound is the air being released from the hose of the pump itself. No air is released from your tire.

Can I buy replacement parts?

Yes. We designed the Zilch head to be your last. All parts are user replaceable.

I already have a floor pump, can I just buy the Zilch head?

No. We decided not to offer the Zilch head as a stand alone item for two reasons. 1. The one handed ergonomic dock positioned high on the pump handle is part of the overall experience of using the Zilch head. 2. The larger share of the cyclists market is not comfortable with the somewhat complicated process of replacing the head on their existing pump.

When will it ship?

July.

The Zilch Head is ready to enter the beginning stages of mass-production. We expect most of production to occur during the months of May & June, and during that time we should have batches of shipments headed to our US operation via sea freight, for assembly and US Fulfillment. EU backer's rewards ship from our EU warehouse partner.

How will my products ship and will I get tracking?

If you're in the US, we'll be shipping your package from our Florida operation using a ground service (FedEx depending on destination and shipment size). These packages will have tracking information that will work within the US.

INTERNATIONAL:
Non-US orders will ship from one of our EU warehouse located in the Ireland. In order to provide a better fulfillment experience (and in some cases reduce duties that customers have to pay), Radian USA is going to be importing all of our products into the EU prior to shipping them to you. This means that your shipments:

1. Won't require duties to be collected on delivery in UK, EU, (other countries may have applicable duties, please check with your customs office for specific details. Customers are responsible for paying local sales tax / VAT/GST, which will be calculated and charged when you fill out your fulfillment survey and enter in your shipping information.)
2. Will arrive quickly and not get held up in customs.
3. Will have tracking.
