PrestaCycle Prestaflator Digital Multipurpose Bicycle Inflation Tool

Product No. pc-77091

The new Prestaflator Digital is made possible by our new Rapid Response™ Digital Gauge. During inflation, the gauge is capable of showing immediate changes in pressure, enabling fast inflation -- now with supreme accuracy. The gauge uses highly accurate, non-wearing circuitry for pressure readings, so it does not wear-out or loose accuracy like traditional Dial gauges. Highly accurate readings are across the whole range, making this tool excellent for Fat Tire, Cyclocross, MTB as well as Road Bikes. Easy Tool-less replacement of the two CR2032 batteries (included).

Excellent Air Flow control.

The Prestaflator is designed with a long-throw trigger valve. Use a light squeeze or brief, rapid shots to gently inflate Bike tires to your desired pressure over a few seconds. A full squeeze on the trigger provides maximum pressure for seating tubeless tires. Designed for MTB & Road tires with a wide range of pressure requirements.

Quick-Click2™ Head for Tubeless & removable cores.

The Prestaflator Head includes a removable cap with our new Quick-Click2™ push/pull head. Quick-Click2™ is the fastest and easiest Presta valve connection. Our original Quick-Click™ and our new Quick-Click2™ heads should be used with all Tubeless applications and any tubes with removable valve cores.

1way / 2way Presta Inflation Head inside.

Inside the Prestaflator head is our 1 way / 2 way Spin-on Presta design for inflating and deflating tires with traditional Presta valves. A few quick turns secures the head to the cap threads on the Presta valve and provides an air-tight seal. It has an internal sliding-action. Push the hose towards the head to push the Presta valve air release button without removing the head. This allows the Prestaflator to take a tire pressure reading without being connected to an Air Compressor. It can also let air out of the tire by simultaneously pushing the hose and pressing the air release button on the side of the Prestaflator handle. When you inflate or take a pressure reading, the head automatically slides back away from the Presta button. This returns the Presta valve to it’s natural one-way operation. This means there’s absolutely NO pressure loss when you disconnect the head from the tire.

Quick-Click2™ has the best seal plus the easiest installation & removal of any Disc head. Smallest head – fits ALL Disc wheels. Works so well it’s an everyday-use Presta head. Right-angle design is great for tight areas with Standard Schrader air valves. Firm spring clip holds at high pressures. Low profile design fits Kids bikes, Scooters and Motorcycles. The Big Quick-Click™ push/pull Tubeless Presta head works with or without the valve core removed for high flow tire seating. Shop duty for long-life Presta inflation. Prestacycle 1/4″ I/M 6061-T6 Alloy Quick Coupler Kit upgrades all your air tools to Prestacycle quality. 1/3 the weight of Steel or Brass, makes your air hose easier to handle.


Prestaflator is engineered specifically for the needs of bicycles and bicyclists. Only top quality materials are used for it’s components. We start with a cast Aluminum body and give it a bead blasted finish. Next we use 6061-T6 Alloy, Chrome and Stainless Steel components for all connectors and moving parts. The hose is made of reinforced polyurethane. It’s 3X more flexible than our original Black hose and is rated for 300 PSI of continuous use. Smooth alloy clamps on the hose are more comfortable for use of the spinner head and are corrosion resistant.

Prestaflator’s unique variable-rate trigger plunger is long and narrow. Behind the trigger is a high-force spring. This allows the user to more easily regulate very small amounts of air to reach the exact pressure desired in even the smallest racing tires.


Prestaflator is designed to offer years of reliable service. The body has a ¼” male threaded adapter so you can install many types of connectors. It comes with the most commonly-used ¼” I/M Quick Coupler in the box and ready to install with no tape or glue needed.

The hose, trigger and pressure release mechanisms are all threaded and installed using #7 O-Rings. They can all be removed and serviced with a 14 mm wrench. We offer rebuild kits so you can service and maintain your Prestaflator anytime.

The Presta / Schrader heads and couplers are made of 6061-T6 Alloy. They’re as strong as Brass, but only 1/3 the weight. This is no place for plastic. Drop your hose on the concrete with plastic pump heads and they could break. The Presta head connects to your tire valve with our new improved easy-on easy-off “Urethane pump head gasket”. Replacements are available on our website or through any cycling supply source.

Automotive Inflators

Automotive inflators are not the same as Prestaflator and may not be safe at bicycle pressures. They use lower quality materials throughout, one-time glue assembly and low grade plastic pressure gauges to bring down the quality and price. Don’t let a gauge with a high pressure range fool you ... inside the package are safety warnings. Even one with a 230 PSI gauge may only be rated for 70 PSI maximum use. Use one of those on a bike and the weaker seams on the body may crack, the air hose could burst or the connector could blast off the wheel. As soon as one seam or glued seal fails you get no reading from the pressure gauge. Failure and disposal of automotive inflators is common.
