FLO Air Gage Info

The FLO Locking Chuck is a specially designed device that locks on to a Presta valve to prevent air loss during inflation. The FLO Locking Chuck features an innovative dial design that creates a precision lock and a unique trigger grip allowing for a quick release without air loss.

The FLO Locking Chuck is plastic free and made from a combination of steel, aluminum and rubber.

Thread the FLO Locking Chuck onto any Schrader style pump to make inflation a breeze.

Why We Made This:
We designed the FLO Locking Chuck due to many frustrations with existing chucks when developing the FLO Air Gauge.

Getting Started

To learn how to use your FLO Locking Chuck please watch the video below.

Maintenance

Check the FLO Locking Chuck for seal wear every 6 months. All parts are replaceable.

Optimize your tire pressure for your weight, riding surface, tire casing width, and internal rim width by using the tire pressure recommendation table below. The pressures listed are starting recommendations. We suggest experimenting with your tire pressure to find what is the fastest for you and the roads you ride. Remember, being slightly lower is better than being slightly higher.

Follow these steps to use the table:

Weigh yourself and your bike together.
Find your wheel model.
Determine your riding surface. This will be a pavement or gravel variant.
Measure the width of your inflated tire on your rim.
Find your tire width under your road surface type.
Match your riding surface and tire width to your bike and rider weight.
Use this pressure (psi) and enjoy your ride!
