Lezyne Alloy Drive

This is a high-volume pump, which is specifically engineered for mountain and gravel bikes. It moves a large amount of air quickly to inflate wider, lower-pressure tires, rather than trying to reach the very high pressures required for skinny road tires.

Yes, the included ABS Flex Hose is compatible with both Presta and Schrader valves. You simply flip the internal fitting inside the hose to switch between the two valve types.

The flexible hose is a significant advantage because it prevents you from accidentally bending or snapping the valve stem while pumping. It allows you to hold the pump comfortably in one hand while the hose absorbs the movement, reducing stress on the valve.

Yes, the tool is built into the hose and is designed to help you tighten or remove a loose valve core. It is a handy feature to have if your valve core vibrates loose while riding, which can cause air to leak unexpectedly.

The small version weighs 114g and the medium weighs 130.7g. Because it mounts securely to your frame using the included Composite Matrix bracket, the weight is negligible and keeps your pockets or pack free for other essentials.
