Lezyne Alloy Drive

Yes, the Lezyne Alloy Drive features a reversible head design that allows you to switch between Presta and Schrader valves quickly and easily.

The pump weighs 126 grams and measures 166 mm in length. Its compact size makes it small enough to fit comfortably in most standard jersey pockets or a small saddle bag.

The Alloy Drive is rated for a maximum pressure of 90 PSI. It is specifically designed for high-volume tires, making it better suited for mountain or gravel bikes rather than high-pressure road tires.

The flexible hose is stored inside the pump barrel when not in use. When you need to inflate a tire, you simply unscrew the cap, pull the hose out, and thread it onto the valve, which helps prevent strain on the valve stem while pumping.

No, the Lezyne Alloy Drive does not have a built-in pressure gauge. You will need to rely on feel or a separate tire pressure gauge to determine when your tire is properly inflated.

The built-in air bleed system allows you to release excess air pressure from the hose before disconnecting it from the valve. This helps protect your valve cores from damage and makes it easier to remove the pump head after inflation.
