Clik Valve technology eliminates the threaded valve core that makes traditional Presta inflation a two-handed operation. Instead of unscrewing a tiny brass tip, holding it open, and trying to seat a pump head simultaneously, Clik valves use a spring-loaded mechanism that opens automatically when the pump chuck connects and seals when it's removed. The Lezyne Clik Drive HP pairs this valve system with a compact high-pressure hand pump designed specifically for road and triathlon tires that need to reach 100+ psi from a portable tool.

The pump connects via a flexible hose rather than directly threading onto the valve stem. This flex hose approach puts distance between the pump body and your wheel, which means you can brace the pump against your thigh or the ground and generate full-stroke power without putting lateral stress on the valve. A bleed valve integrated into the hose lets you fine-tune pressure after inflation—if you overshoot your target, you can release small amounts of air without disconnecting and reconnecting.

Maximum pressure reaches 160 psi, which covers road tires with room to spare. The HP designation indicates high pressure optimization, meaning the pump cylinder diameter is sized for pressure rather than volume. Each stroke moves less air but generates more compression, which is what you need when pushing past 80 psi where larger-diameter pumps start requiring excessive force. For gravel or mountain bike tires that run lower pressures and higher volumes, Lezyne makes a separate HV (high volume) version in the same Clik Drive lineup.... Read More
